How to Nail-Down Solid Strand Bamboo Flooring | Trinity Bamboo

How to Nail-Down Solid Strand Bamboo Flooring | Trinity Bamboo

If you have a plywood or OSB subfloor on or above grade (ground level), a nail-down installation of your new Trinity Bamboo Solid Strand Bamboo flooring provides one of the most cost-effective and resilient installation methods available. 

With all brands of Strand Bamboo, there are two primary considerations to take into account as you prepare to nail-down your new flooring:

  1. All Solid Strand bamboo flooring is very hard and very dense
  2. Not all nailers and fasteners work with all brands of Solid Strand Bamboo flooring

First, let’s talk about hardness and density.  Trinity Bamboo’s Strand bamboo is both really hard and really dense.  How hard is it?  For perspective, Red Oak has a Janka Hardness rating of about 1290.  Trinity Bamboo’s Strand bamboo, on the other hand, has an average Janka Hardness rating of about 3700 which means that it is 186% harder than Red Oak!  Why is this a great thing?  Like other super-hard and dense tropical hardwoods, Trinity Bamboo’s Strand Bamboo is very difficult to dent and, as such, you may never need to sand out dents from its surface.  This is great!  Why do you need to take density into consideration when nailing-down a Solid Strand Bamboo floor?  My favorite analogy is that of a glass of water.  If you put your finger into a glass of water, the level of the water will rise around your finger because the water is dense to the point where it is non-compressible.   Strand bamboo is not so different.  If you use a traditional 15 gauge flooring cleat nail (this is the size nail used since the 1950's to install classic site-finished 3/4" oak etc.) the Strand Bamboo will rise around the nail forming a slightly raised area known as a dimple.  This is bad.  The solution?  Use an 18 gauge cleat nail which is thinner and has less mass than a 15 gauge cleat nail.  The bottom line is that an 18 Gauge Cleat Nail has enough strength that it will pass through the super dense Strand Bamboo but not so much mass that it will cause dimpling.  It is the perfect solution.

Can I use 18 gauge staples?  I’m glad you asked.  No.  Please don’t.  If you try using staples more than likely you'll just waste your time and damage a bunch of planks.  18 gauge staples are just not as strong as cleats and many of the staples will crumple and fold when they are shot into the flooring.  Staples are also more likely to damage the plank’s tongue.  Stick with 18 gauge cleats - it is a proven solution.

What type of nail gun should I use?  The reality is there are probably a number of brands of 18 gauge cleat nail guns which will get the job done.  Having said that, the last thing you want to do is to buy a nail gun only to find that it doesn't work as well as you wish it did.  To help Trinity Bamboo's flooring customers find a reliable solution, we worked with Powernail to test their American-Made Cleat Nailers with our Tongue and Groove flooring to ensure we can provide our customers with a tested and proven nailing solution. The following images and their associated comments were provided to Trinity Bamboo by Powernail as part of a report documenting their testing program.  Thank you Powernail!

Powernail 50F 18 Gauge Nailer

If you are a professional flooring installer and you are nailing-down Strand Bamboo flooring day in and day out, try the Powernail 50P Flex nailer.  If, on the other hand, you want a nailer that is a bit easier to use and costs less money, try the Powernail 50F. In my opinion the Powernail 50F is the PERFECT nailer for Contractors and DIY types and the price is competitive with some much lower-quality brands available out there on the web.  Most importantly, both the 50P and the 50F cleat nailers have been tested with Trinity Bamboo flooring and will get the job done, each and every time.

What length nail to use?  Try the 1 ½” HD Cleat Nails from Powernail.  The patented head of the Powernail 18 gauge HD cleat is unique in its shape and is designed to reduce tongue splitting.  This length of nail is optimal for a nominal ½” thick flooring plank and will not over-penetrate typical ¾” Plywood sheathing.  

Powernail 18 Gauge 1.5 Inch Cleat Nails

Communicate with your installer: Last and not least, even though your installer should read the installation guidelines and know to use an 18 gauge cleat nailer when installing Solid Strand Bamboo, it never hurts to remind them. Remember, most installers will have a 15 gauge nailer in their truck and that is the tool they will turn to unless told otherwise.  Don't let that happen.  Protect your investment by agreeing to an installation plan with your installer before they start the job.  That installation plan should definitely include the use of an 18 gauge cleat nailer.

As always, if you have any questions, please call the Trinity Bamboo team at 1-888-248-6538.  We'd love to help!

Complete Guide to Strand Bamboo Floor Maintenance | Trinity Bamboo

Complete Guide to Strand Bamboo Floor Maintenance | Trinity Bamboo

So, you’ve chosen a beautiful new floor and you had it professionally installed or, you even installed it yourself.  Well done.  The hard part is now behind you. Thankfully, unlike most other things in life, flooring maintenance is quite simple: In short: Keep your floor dry and clean up grit whenever and wherever it is present and all will be well.   Having said that, a floor is a FLOOR and it is, by its very nature, subject to the worst of what our kids, animals, and the world will throw, shed, drop, drip, and or spill on it.  Floors will age a bit over time – there is no way around it, so relax into it, and as the old saying goes, just do your best!

Now, here is how to keep your bamboo floor looking as beautiful as possible: 

  1. Try to keep your home’s relative humidity (RH) as close to your Installation Average RH as possible.  This will prevent the problems associated with very dry or very humid environments.  For further information on acclimation read this article: Why you need to acclimate your new floors. 
  2. Clean up spills as soon as they happen.  Like other natural materials, if bamboo flooring is exposed to liquid for a prolonged period it can be damaged.
  3. Use a walk-off mat (also called an entry mat) at exterior doors to prevent dirt and grit from being tracked in.
  4. Vacuum (without the beater bar turned on) to remove dust/grit/dirt or use a microfiber mop system both for removal of dust/grit/dirt and for damp mopping the floor.
  5. Damp mop your floor using microfiber mop.  You can use Bona Hardwood Floor Cleaner if you wish – mostly I just use water.  The key is to use as little liquid as possible.  I wring out my microfiber mop until it is almost dry.
    • Note: If you want to use soap use a liquid dish detergent such as Lemon Fresh Joy.  Just a few drops in a gallon of warm water changes the whole equation.  What we don’t want is soap residue on the floor.  Don’t use soap every time you mop…just use it as needed.  Let me say it again, you want your mop to be almost dry.
  6. Spot clean greasy or other really dirty spots with a sponge or rag and soap water.  Once the spot is clean, rinse the area with a damp and soap-free towel and then use a dry towel to dry the floor.  Note: never use the “scrubby” side of a sponge as it may lightly abrade the floor surface and change the gloss level.
  7. Never use Oil Soaps as they may leave an oily film on the surface of your floor.  Let me repeat this: NEVER use oil soaps.  Never.  No.
  8. Never use floor polish or “refresher” products.  These will likely leave a coating or film on top of your floor and can “dull” the finish.
  9. Scratches:  Because a scratch physically changes the floor the goal is not to “repair” the scratch but to “minimize” its undesirable appearance.   If your floor is scratched, consider one of the following options:
    • If the scratch is only in the coating and hasn't reached the bamboo underneath the coating, drop by your local “health-food” store and get a tiny bottle of Jojoba Oil.  Rub this oil into the scratch, wipe up any excess, and then buff the area with a clean, dry towel.  Due to the waxes present within Jojoba oil its use really diminishes the visual impact of the scratch (it makes the scratch less-white).  Don’t smear Jojoba oil everywhere, just apply it to the scratch.
    • If the scratch is deeper (into the bamboo), use a brown or color appropriate dry-erase marker.  Really rub it over the scratch and let the ink dry.  Then, use a clean cloth to wipe the excess pigment off the surface of the surrounding plank.  Note, if you need more assertive coloration try using a Sharpie but be careful – it can leave ink on the surface of a plank.  Try rubbing it off the surface of the plank immediately after application using a towel or your thumb. Darker colors applied to a scratch typically are less visible than lighter colors (for example, if you have a brown floor try dark brown ink).
    • Mandatory: when applying ink to a scratch (whether you are using a Dry Erase marker or a Sharpie), test your repair on an extra piece of flooring FIRST.   If you don’t have any extra flooring sitting around just give us a call – we’ll send you a scrap to do your test on.
  10. Make sure that you have furniture pads on the legs of all chairs and furniture.  I’ve had great success with the pads that “nail in” to the chair leg (I find that the pads which rely on adhesive work well for objects which rarely move but not for chairs).
  • Note: If you can get away with it, these cat paw socks do a great job at protecting your floor from your chairs!! My kids and I love them, my wife...not so much.  I had to sneak them on while she was out of the house.

  1. Use rug pads if desired:
    • Polyvinyl-Based (PVC): Many inexpensive pads have a PVC composition and may emit VOC’s (volatile organic compounds such as formaldehyde etc.)  These budget pads may also react with the polyurethane coatings used on flooring which could cause discoloration.  The word on the street is to stay away from PVC rug pads.
    • 100% Natural or Synthetic Rubber Pads: 100% rubber pads provide an effective non-stick grip to the flooring surface.  Ensure that the pads contain no fillers (such as clay) as some of these fillers can abrade the surface of the polyurethane and dull their surface.
    • Felt/ Rubber Hybrid Pad: This is a great way to go as the hybrid pad provides both cushioning as well as the gripping attributes of the rubber. Again, make sure there are no fillers.
  2. Move and rotate rugs and furniture to prevent sun exposure lines.  If you have a room which receives direct sunlight or is lit with powerful lamps, be aware that many materials (wood, fabric, bamboo) are sensitive to light and can darken or lighten with exposure to sunlight or powerful indoor lights.
  3. If your floor’s coating ever becomes damaged to the point where you want to refinish it, consider this option: Sandless Recoating.  Rather than sand down your floor to the raw wood/bamboo prior to recoating, the surface is deeply cleaned and lightly abraded.  Then, a new coating is applied directly to the freshly cleaned and abraded surface.  The benefits of Sandless Recoating systems are as follows:
    • Fast (can take as little as a day)
    • May cost less than traditional sand and recoat processes
    • Maintains the integrity and color of your floor (no bamboo is sanded away giving your floor an unlimited life-span)
    • Note: with softer woods where folks are trying to sand-away dents, Sandless Recoating may not be an effective restoration method.  With Strand Bamboo which is very resistant to denting, Sandless Recoating works GREAT.
  4. That’s it!!  As always, if you need help or have any questions whatsoever, feel free to call the Trinity Bamboo team at 1-888-248-6538.

gb&d: Everything You Never Knew About Strand Bamboo

gb&d: Everything You Never Knew About Strand Bamboo
By Kate Griffith for Green Building and Design Magazine

Trinity Bamboo delivers a durable, beautiful, sustainable option for your floors.

Tom Goodham’s career as a leader in sustainably derived hardwood flooring started with a fascination for unusual solutions. “I was captivated by the idea that there were options for hardwood flooring that didn’t have anything to do with traditional hardwoods, that people were making this product out of fast-growing bamboo,” says Goodham, president of Trinity Bamboo and former vice president of manufacturing and operations for Teragren Bamboo. That product was traditional bamboo flooring, and it was the only style of bamboo flooring available from approximately 1995 when the industry started until 2005 when Strand Bamboo hit the market.

Unlike traditional bamboo flooring in almost every way, strand bamboo combined the durability and dimensional stability of tropical hardwoods with the green credentials of traditional bamboo flooring products. “The first time I saw strand bamboo I knew it was going to revolutionize the world of flooring,” he says.

Durability & Hardness

Few traditional hardwoods offer the performance characteristics of premium strand bamboo flooring. With an average Janka rating of 3500 (Janka measures the force required to embed a .444-inch diameter steel ball halfway into a sample of wood)—strand bamboo is 141% harder than North American hard maple. “Strand bamboo is very difficult to dent, and, thanks to the screen and recoat refinishing process, has an almost unlimited life span in typical commercial or residential spaces,” Goodham says.


Having a dimensional change coefficient of .0014, strand bamboo flooring is one of the most dimensionally stable natural materials used in construction today. “To find a hardwood as hard and as dimensionally stable as strand bamboo you’d have to go to quarter-sawn teak or mahogany,” Goodham says. But these tropical hardwoods are mostly harvested from rainforests, increasing stressors on already struggling ecosystems.

Sustainable Sourcing

Rapidly renewable, Moso bamboo’s cultivation and harvest does not result in damage to its forests. Grown on lush mountainsides in China, this perennial grass is cut by hand by villagers who lease the harvest rights from their local government. Its rapid regrowth means bamboo forests sequester more carbon than typical hardwood forests. “These are largely naturalized strands of bamboo that require no irrigation or pesticides,” Goodham says. “Because bamboo culms are harvested and transported off the mountain by hand, the soil and ground cover is not disturbed, which reduces or eliminates human-caused soil erosion.”


Bamboo is naturally a light maple color and, like many hardwoods, is often sanded until it is perfectly smooth. Like other hardwoods, strand bamboo takes well to texturing and staining. “Strand bamboo is a chameleon in that, as a manufacturer, I can make it look like any species of hardwood I want,” Goodham says.

In addition to color options, wire brushing and hand-scraping treatments give Trinity Bamboo’s strand bamboo a natural-looking grain that Goodham says helps to hide the reality all flooring experiences—dirt, scrapes, and scratches. When he started Trinity Bamboo in 2016, he wanted to sell flooring products with an authentic texture. “Our culture is attentive to changes that mar a perfect finish—think of the first scrape on your new car’s bumper—but floors are floors. You walk on them. We run, play, slide, hop, entertain friends, feed dogs, roll Hot Wheels, and otherwise live life to the fullest on our floors,” he says. “A floor is like a human—a bit of character hides the wear and tear of daily life. Aren’t we all happier that way?”

Who is Tom Goodham?

Tom Goodham’s entrance into sustainable flooring started when he joined Teragren Bamboo in 2003. “We were sustainability activists, riding the crest of the green wave and carrying with us the enthusiasm and fervor of those who had figured out it’s possible to have fun and succeed in business by taking care of the planet, our workers, and our customers,” he says.

During his 13 years at Teragren, Goodham learned the ins and outs of manufacturing, logistics, and sourcing from operations in China. “I learned how to manufacture the best flooring. I learned who the craftspeople were. And most importantly, I learned how to do business in China without cutting corners—ever.” In 2016 he decided to start his own company, Trinity Bamboo, and apply everything he learned with the goal of bringing the highest quality flooring product possible direct to builders, developers, and end-consumers. “Trinity Bamboo is built on three core principles: quality, integrity, and value, none of which are optional,” he says. Trinity Bamboo’s flooring is also FloorScore Certified and Clean Air Verified.

Did You Know?

Dimensional change coefficient measures the expansion and contraction of a material in environments with shifting temperature and humidity levels. The more a material expands and contracts, the more difficult it can be to use in dry and humid climates. “To me the greatest attributes of strand bamboo are its hardness and dimensional stability,” says David Keegan, president of Seattle-based manufacturer Bamboo Hardwoods and a longtime industry colleague of Goodham. “There are simply no other flooring options that exhibit such durability and stability.

Acclimation: How to Acclimate your Trinity Bamboo Floor

Acclimation: How to Acclimate your Trinity Bamboo Floor

A question that all folks should be asking is “do I need to acclimate my new floor before I install it, and if so, for how long?”  What makes this topic a bit difficult is the number of variables involved.  Let’s get a few terms out of the way so that we are all speaking the same language.

Relative Humidity:  Roughly speaking, relative humidity (RH) is the amount of water vapor present in air as a percentage of how much water vapor the air can potentially hold at a given temperature.  Warmer air, for example, can hold more moisture vapor than colder air.  So, air with 70% RH at 80 degrees Fahrenheit will have more actual moisture in it than air at 70% RH at 20 degrees Fahrenheit (even though the reading at both temperatures would be 70% RH).  Technical explanations aside, if your house has a high relative humidity it has more moisture in the air than your house does when it has a low relative humidity.  Muggy versus dry air.  Hawaii versus Mojave Desert. 

Moisture Content:  The moisture content of the wood/bamboo in your home is determined by two factors: Your home’s temperature and your home’s relative humidity.  If you increase the temperature and relative humidity level in your home, the moisture content of all the wood/bamboo in your home will rise and the wood/bamboo will expand.  If you decrease the temperature and relative humidity level in your home, the moisture content of all the wood/bamboo in your home will decrease and the wood/bamboo will shrink. 

Acclimation: Bamboo and wood flooring interact with the surrounding environment (subfloor, air, dogs, etc.) and take on moisture or give off moisture until a state of equilibrium is reached with the environment. Acclimation is the art (and the science) of preparing your new floor for installation by allowing it to reach a moisture content level in equilibrium with the average air temperature and relative humidity levels inside your home.  Your new floor should be acclimated prior to installation.

The following chart shows the approximate moisture content of wood/bamboo when it has reached equilibrium with (is acclimated to) air at a specific temperature and relative humidity level:

To put the above chart into practical terms, if you remove a flooring plank from a new box of flooring and it has a moisture content of 8.5% at 70 degrees, it will not expand or contract when placed into a 70-degree house which has a relative humidity content of 45% (known as 45% RH). See the purple areas in the above chart.  To put it another way, a plank at 8.5% moisture content is in equilibrium with air at a temperature of 70 degree at 45% RH.

What happens if we install the same plank into a house with an interior relative humidity of 60% RH at 70 degrees?  The moisture content of the plank will rise until it reaches equilibrium with the environment.  This means that your plank will swell until its moisture content reaches 11%.  If you install this same plank into a house with an interior relative humidity of 30% RH at 70 degrees, your plank will shrink until its moisture content reaches 6.2%.  This swelling and shrinking of wood/bamboo is totally normal and happens around us all the time.  The key here is that we want most of the swelling or shrinking to occur before you install your new floor to avoid problems such as buckling (from excessive swelling) or gapping (from excessive shrinking).  How do we avoid these problems?  Acclimate prior to installation.

Your mission is to acclimate your flooring at, and install it into, a temperature and relative humidity controlled environment representing the average environment you expect to be present in your home year-round.  Again, we don’t want to acclimate and install into an abnormally cold and dry house nor do we want to acclimate and install into an abnormally humid and hot house.  We want to acclimate and install your floor into the average environment (temperature and relative humidity) your house will be maintained at year-round.  How does a person know the average temperature and relative humidity levels inside their house?  One option is to keep records of your house’s average temperature and relative humidity levels.  Thankfully, this is easy (and fun!).  Purchase a low-cost digital Thermometer and Hygrometer (around $15.00) and then take notes.  If you don’t have a year to monitor readings in your house see if any of your neighbors have a weather station and see what their indoor environment is like over the course of a year.  A call to your local HVAC specialist might provide you with some excellent insight as well.  Bear in mind that your house (with your heating and cooling system) will assuredly be a bit different than your neighbors’ house.

If you can’t get any local data, take a look at the following chart created by The USDA Forest Products Laboratory.  It lists the average moisture content of wood in interior environments across all the states in North America. 

United States Department of Agriculture, Forest Products Laboratory FPL–GTR–190

How would you use the above chart?  Example: You live in North Dakota.  The chart shows an average moisture content for wood at 8%.  You keep your house at 70 degrees year-round.  You should, ideally, acclimate your floor at a relative humidity level between 40% and 45%.

How to Acclimate your new Floor:

Once all “wet-work” has been complete (plaster, painting, etc.) make sure your Heating/Cooling system is operating and set to the average temperature and relative humidity your house will be maintained at year-round.  Next, remove all the planks from the boxes and sticker stack them off the floor so that the planks are adequately exposed to the air in the installation environment.

Sticker Stacking in real-life brought to you by Robert Rosser and his excellent team in Florida: Note that every layer is separated by cardboard (cut from the box) to allow for air-flow between planks.

How long will acclimation take? A good rule of thumb is to acclimate your Strand Bamboo floor (engineered or solid) for about 7 days per every percentage point of projected change in moisture content.  Because Trinity Bamboo flooring will be delivered to you having an average moisture content of 8.5%, I would suggest the following acclimation schedule:

  • Acclimate (out of the box and sticker-stacked) for an absolute minimum of 72 hours (for perfect environments) or 7 days per desired 1 point change in moisture content:
    • Example: If your house has an interior average relative humidity level of 35% at 70 degrees you will need to acclimate your floor to a target moisture content of 6.9% prior to installation. To do this, you will need to acclimate your flooring for about 11 days.  Here’s the math:
      • 5% - 6.9% = 1.6 points change
      • Multiply 1.6 x 7 days = 11.2 days acclimation
    • If you live in coastal Florida where your house has an interior average relative humidity level of 65% at 70 degrees, you will need to reach a target moisture content of 12% prior to installation. To achieve this, acclimate for about 25 days.  Here’s the math:
      • 12% - 8.5% = 3.5 points change
      • Multiply 3.5 x 7 days = 24.5 days acclimation

Use a moisture meter to confirm your flooring is acclimated to the environment.  How will you know when acclimation is complete?  The moisture content of your floor will no longer change (or will change very slowly).  When in doubt, more acclimation is better, as long as you are acclimating your flooring to the average annual relative humidity and temperature range for your house.  Again, never acclimate to an extreme environment.  Always acclimate to your household average relative humidity and temperature.

How to measure moisture content (MC):  In truth, it is difficult to know the exact moisture content of any natural flooring, bamboo or wood.  Why?  Because moisture meters (by necessity) make a lot of assumptions about the density and composition of the material they are measuring.  If the density of the material being tested is different than the standard, guess what?  It will measure a bit high or a bit low.  Just like any other natural material, all Strand Bamboo flooring has varying degrees of density from batch to batch and even from plank to plank.  Well then, how then do you know if your flooring is acclimated to an environment?  It’s moisture content will stop changing.  This is where the moisture meter really comes into play.  Rather than test flooring planks to obtain an exact moisture content, test planks to understand when their moisture content is no longer changing.  The good news is that almost any moisture meter can do this.

As always, every situation is a bit different.  This is why it is sometimes important to hire a professional to perform your flooring installation.  Don’t cut corners and don’t hire someone who will.  If you have any questions give us a call at 1-888-248-6538.  We’ll gladly spend as much time working with you as you need.  Free technical support from kind people – we’re Trinity Bamboo.

Solid or Engineered Flooring - How to Choose | Trinity Bamboo

Solid or Engineered Flooring - How to Choose | Trinity Bamboo

Congratulations!  You’ve found the perfect Trinity Bamboo Floor: The price is just-right, the color matches your dogs, the texture matches your lifestyle, and now you are sitting in your living room showing your flooring samples to your installer.  Your installer smiles, nods encouragingly, and asks you whether you are purchasing a Solid or an Engineered Floor.  This is the moment you’ve been waiting for.  Without skipping a beat, you confidently answer the question and you even up the ante by suggesting an installation method.  The installer looks at you with admiration because you are clearly smarter and wiser than most customers.  This is one of life’s sweet moments…savor it.

In the following article, you will learn the difference between a Trinity Bamboo Solid Strand Bamboo Floor and a Trinity Bamboo Engineered Strand Bamboo Floor, why to choose one product over the other, and which installation method to use to install it. 

Trinity Bamboo Solid Strand Bamboo Flooring: 

Trinity Bamboo’s Solid Strand Bamboo flooring is made of one material, Strand Bamboo, through and through.  Other than having a premium urethane coating on both the top and bottom surfaces, there are no layers or plies; it is one homogeneous material with the grain running the length of the plank. 

Trinity Bamboo's Solid Strand Bamboo Flooring has a Tongue and Groove milling profile on all 4 edges and is designed to be nailed-down to a wooden subfloor on or above grade (ground level) or glued-down to a cement or wooden subfloor on or above grade.  Trinity Bamboo Solid Strand Bamboo Flooring should not be installed below grade (below ground level).  Trinity Bamboo's Solid Strand Bamboo Flooring may be installed over Radiant Heating systems (on or above grade) using the nail-down method following NWFA Radiant Heat Installation Guidelines. Trinity Bamboo's Solid Strand Bamboo Floors, when nailed-down or glued-down, can wrap through doorways, flow into nooks, and be installed under cabinets and appliances, providing customers with a classic vision of a hardwood floor; smooth, monolithic, and uninterrupted by transition moldings in doorways.  With a well installed Trinity Bamboo Solid Strand Bamboo Floor, there will be no movement or bounce as the planks are firmly attached directly to the subfloor. 

Historically, solid hardwood flooring has been installed using 15 Gauge Cleat Nails.  Why not use 15 Gauge Cleat Nails with Solid Strand Bamboo Flooring?  15 Gauge Cleat Nails are too big.  Think of Strand Bamboo as water.  If you put your finger in a glass of water, the water will rise around your finger, it won’t compress and make room for your finger.  The same is largely true for very dense tropical hardwoods and Strand Bamboo.  If you try to nail Solid Strand Bamboo Flooring with a 15 Gauge Cleat Nail, the bamboo will likely rise around the cleat forming a slightly raised surface called a dimple.  This is less than desirable.  Over the last decade, we have tested many options and found that using an 18 Gauge Cleat Nail solves this problem.  Why?  The 18 gauge cleat provides the perfect balance of nail size and holding power.  The nail size is small enough that dimples are not formed yet the nail is strong enough to provide holding power in almost any wooden substrate.  To correctly use an 18 Gauge Cleat Nail, place your nail gun against the tongue edge of the plank at a 45-50 degree angle ensuring that the head of the freshly fired Cleat Nail rests cleanly in the nail pocket.  If you must use 18 Gauge Staples, be forewarned that, depending on the quality of the steel used by the manufacturer of your staples, many of your staples may “curl” due to the density of the Strand Bamboo.

Trinity Bamboo Engineered Strand Bamboo Flooring: 

Trinity Bamboo’s Engineered flooring is constructed of three visually distinct layers: Strand Bamboo, High Density Fiberboard (HDF) made from Poplar, and a Poplar balance layer.  When combined, the three layers form a durable and highly dimensionally stable flooring plank designed to be floated over (rest on top of) or glued-down to almost any kind of level subfloor.  Our Engineered Flooring Planks are milled with the UNICLIC® L2C Locking System. Plank side-joints are milled with a Fold-Down Lock System and plank end-joints are milled with an Overlap to Lock system for easy Floating installations above, on, or below grade (ground level), and easy Glue-Down installations above or on grade.  Trinity Bamboo's Engineered Strand Bamboo Flooring may be installed over Radiant Heating systems (above, on, or below grade) using the floating method following NWFA Radiant Heat Installation Guidelines

Engineered Floors were designed to handle challenging installation situations such as “below-grade” (below ground-level) installations and installations over radiant heating systems.  How is this magic possible?  These floors are designed from the ground-up to be dimensionally stable.  In other words, when exposed to dry (below 35% Relative Humidity) or moist climates (above 55% Relative Humidity), a typical Engineered Floor will expand and contract less than a Solid Hardwood Floor will.  (Interesting Note: Unlike traditional hardwoods, Solid Strand Bamboo has an almost identical dimensional change coefficient as its Engineered counterpart.  What does this mean?  It means that when exposed to dry or moist climates Trinity Bamboo Engineered Flooring will expand and contract the same amount as Trinity Bamboo's Solid Strand Bamboo Flooring).  It is important to note that because Trinity Bamboo's Engineered Flooring planks are locked to each other (literally), when one plank moves it will end up pulling or pushing every plank directly or indirectly attached to it.  To understand these forces, imagine the following experiment: Tape three sheets of paper together at the corners.  Now pretend that each piece of paper is a room with an engineered floating floor installed into it.  Each room is joined to the next room in the doorways via the floor’s locking system.  Ok – here we go: pull on one piece of paper.  Did all three pieces of paper move?  Yes.  Now, push on the first piece of paper.  Did the first piece of paper begin folding because it was pushing against the weight of all the other two pieces?  Yes.  Now, put a cup of coffee on the third piece of paper and pull on the first. Where do the pieces of paper break apart?  The taped joint.  The problem you just discovered with the pieces of paper is EXACTLY what will happen if you install an Engineered Floating Floor using the floating method without separating each room from the next one using an expansion / contraction joint such as a T-Mold.  I will say it here once and for all: When installed as a floating floor, Trinity Bamboo's Engineered Flooring must be installed into rooms with each room separated by an expansion joint.  THIS is the secret to successfully installing flooring using the Floating method.

Why to Choose Solid or Engineered Flooring:

Trinity Bamboo Solid Strand Bamboo Flooring - Why to Choose:

  • You want to Nail Down your floor to an OSB or Plywood Subfloor on or above grade (ground level)
  • You want to Glue-Down your floor to a Cement, Particle Board, OSB, or Plywood Subfloor on or above grade (ground level)
  • You want your installation to wrap through doorways and between rooms without needing to install transition moldings in doorways or between spaces

Trinity Bamboo Engineered Strand Bamboo Flooring – Why to Choose:

  • You want a Floating Floor
  • You have a radiant heating system and you want to Float your new floor over the top of it
  • You want to easily (and inexpensively) isolate your flooring from the subfloor to ensure that moisture never migrates into your floor
  • You want to install your floor below grade (ground level)

    • Basements (because they are below ground) are very likely to expose a floor to moisture vapor at some point during the life of the floor. The best way to prevent the transfer of moisture from the subfloor into your Trinity Bamboo Flooring is with an absolute Moisture Barrier such as 10 mil polyethylene sheeting.  Make sure your subfloor is level, roll down your polyethylene sheeting running it up the wall to allow moisture to wick to the sides, tape the seams, and roll your 1/8” pad on top of the polyethylene.  Then, install your floating floor over the pad separating all rooms with a transition molding to allow each room to expand and contract at its own rate.

On or above grade installations (concrete subfloors):

  • Product Required: Trinity Bamboo Engineered Strand Bamboo Flooring or Solid Strand Bamboo Flooring
  • Installation Methods: Floating (Engineered Strand Bamboo Only) or Glue-Down Installation (Solid or Engineered Strand Bamboo Flooring)
    • Floating Engineered Strand Bamboo flooring over a concrete subfloor works beautifully. Really, this is one of the primary reasons why Engineered flooring exists. To protect the flooring from potential moisture, simply install an impermeable moisture vapor barrier such as 10 mil polyethylene sheeting over the concrete and then place a 1/8” pad over it. Lay your flooring over the top and you are DONE.
    • Gluing down Engineered or Solid Strand Bamboo flooring onto concrete works great as long as you use a 2 part moisture vapor barrier or a combined moisture vapor barrier/adhesive.  If using a combined moisture vapor barrier/adhesive, please ensure that the system has a perm rating of less than or equal to .183 perm. This is really important. Think of concrete as a sponge.  Eventually, during a particularly wet winter for example, there is a good chance that this concrete will allow some moisture to pass through it.  When that occurs, if there is not an impermeable moisture barrier over the concrete, moisture will enter your flooring and will likely damage it.  Note: when working with adhesive be very careful not to contaminate the surface of the flooring planks with the glue as it may change the gloss level of the plank.

On or above grade installations (wooden subfloors):

  • Product Required: Trinity Bamboo Engineered Strand Bamboo or Solid Strand Bamboo Flooring
  • Installation Methods: Floating, Glue-Down Installation, or Nail-Down Installation method
    • To float a Trinity Bamboo Engineered Strand Bamboo floor over a wooden subfloor, simply roll down a vapor retarder such as Fortifiber Aquabar B, place a 1/8” pad over it, and install your floor over the pad.  Alternatively, install a combination vapor retarder and pad such as the Eco Ultimate Silencer™ and install your floor over it.  Remember, it is very important that adjacent rooms be separated from one another by a transition molding to allow each room to expand or contract independently.
    • To glue-down Engineered or Solid Strand Bamboo Flooring onto a wooden subfloor, apply a premium quality flooring adhesive such as Titebond 771-Step with an integrated vapor retarder.  If you don't use Titebond 771-Step, read the adhesive specifications carefully to ensure that the adhesive is compatible with Strand Bamboo Flooring.  When working with adhesive be very careful not to contaminate the surface of the flooring planks with the adhesive.  No matter how hard you try to remove the adhesive there will likely still be residue which will change the gloss level of the plank.
    • To Nail-down Solid Strand Bamboo flooring onto a wooden subfloor, lay down a moisture vapor retarder such as Fortifiber Aquabar B or the Eco Ultimate Silencer™ and then nail your flooring down using an 18 gauge cleat nailer.  In a pinch, you can use an 18 gauge stapler but, depending on the quality of the steel, you may have more staples "curl" than you would prefer to deal with.  Do NOT use a 15 gauge cleat or staple.  Trust me.

Chock another one up to the goal of Clean Air in your home.

It was announced on January 5th, 2017, that the FloorScore® Certification program has been officially recognized by the U.S. Environmental Protection Agency (EPA) in its Recommendations of Specifications, Standards and Ecolabels, to federal purchasers.  The fact that the EPA is encouraging Federal purchasers to seek out FloorScore® certified products is yet another strong indicator of how important environmental certifications such as FloorScore® should be to all American Consumers.  Why?  Because the air we breathe should be clean.  Is this really so much to ask?

FloorScore® Certification means the following:

    • Note: The standard CREL (Chronic Reference Exposure Level) listed for formaldehyde (reference B) is 9µg/m3 which equals .0073 ppm or Parts Per Million.
  • Audited Factories: The factory where these Certified products are produced is routinely audited by U.S. based Scientific Certification Systems Global Services.  The audits confirm that the materials the factory says they are using are, in fact, being used.

Trinity Bamboo’s Premium Solid and Engineered Flooring products are FloorScore® certified to the following Standard:  SCS-EC10.3-2014 v3.0 and conform to the CDPH/EHLB Standard Method v1.1-2010 (California Section 01350), effective January 1, 2012, for the school classroom and private office parameters when modeled as Flooring.

Trinity Bamboo’s products are also Clean Air Verified®.  Rather than trust that the testing performed by others is always correct, just to be sure, Trinity Bamboo gathers and submits samples from random production runs directly to International Accreditation Service (IAS) Certified Labs in the U.S., for Formaldehyde Emissions testing.

What are VOC’s anyway?  Volatile Organic Compounds are organic molecules which easily evaporate into the air. We are surrounded by VOC’s: some are dangerous and many are not. Whether they are dangerous or not often has a lot to do with concentration.

This brings us to our nemesis: Formaldehyde.  Recently, there has been substantial attention paid to a particular VOC known as Formaldehyde. Why? Formaldehyde is very common because it is emitted from both manufactured and natural materials. In other words, like it or not, it is everywhere.

Where does formaldehyde come from? Formaldehyde is emitted by many things including you, your dog, many composite wood products, trees, some paints, many fruits, adhesives, and wait—almost everything.

Why is formaldehyde bad? In high concentrations, formaldehyde is an irritant and long-term irritation to the human body can be very harmful.  Formaldehyde is considered by the Environmental Protection Agency to be a "probable human carcinogen".

How much formaldehyde is already in the air around you?  The Agency for Toxic Studies and Disease Registry states that the following are common concentrations of formaldehyde:

    0.0002-0.006 parts per million (ppm) in rural and suburban outdoor air

    0.0015-0.047 ppm in urban outdoor air

    0.020-.04 ppm in indoor air

How much formaldehyde does Trinity Bamboo’s flooring emit?  Because Trinity Bamboo is FloorScore® certified, it cannot have Formaldehyde emissions exceeding 0.0073 parts per million (ppm).

As with all Trinity Bamboo testing, you can view and download all of our test results here.

How do I keep formaldehyde levels low in my house?  Remember the “one dog” rule: One dog will smell like one dog.  Two dogs will double that smell…at least. Make smart decisions about everything you purchase.  Every building material used in your home should have documented low-VOC emissions or there is a possibility that their combined emissions will raise the total VOC content in your house above acceptable standards.

You get what you pay for.  It’s true – you know it is.  The fact is, sustainably produced Strand Bamboo flooring is expensive to manufacture.  Any flooring costing less than a product sold by Trinity Bamboo costs less for a reason.  Choose wisely.  Choose Trinity Bamboo.

Seeking Perfection with Strand Bamboo: Quality, Integrity & Value

Seeking Perfection with Strand Bamboo: Quality, Integrity & Value

Let us examine a commonly held assumption about the inevitable wear and tear of all hardwood flooring.  The truth is, many of us expect a new floor to retain the shine and gloss level of a new car even though we are going to walk, run, play, skid, drop sausages, slide, hop, entertain friends, feed dogs, roll Hot Wheels, and otherwise live life to the fullest on our floor.  This is as it should be.  So, how do we avoid denting and scratching our floor?  Should we even try?

In the old days, our industry used to sell a lot of Traditional Bamboo flooring (slats glued together in a Flat Grain and Vertical grain format).  This beautiful flooring was sanded until it was very smooth and then factory coated with multiple layers of UV cured polyurethane.  The result?  A really-smooth floor which reflected light like polished stone.  The problem?  Even though most of this flooring was (still is) about 45% harder than Red Oak, just like oak, it was easily dented by common household activities.  I can’t tell you how many times I heard folks say “I’ve had oak floors for years and they still look beautiful – this traditional Bamboo floor shows every dent!”.  The truth is these customers were right about the denting of their traditional Bamboo floors but NOT about their oak floors.  If they had gotten down on their hands and knees and looked carefully at their Oak floor they would have seen that their Oak floor was likely one unending mass of dents.  However, because of the natural grain patterns and texture of Oak, the dents on their Oak flooring went unnoticed.  In summary, both the Traditional Bamboo and the Oak floors dented, you just couldn’t easily see the dents in the Oak flooring and they were all too easy to see on the smooth Traditional Bamboo flooring.

When I decided to start my own Bamboo flooring company I promised myself that I would sell flooring that had just enough grain and surface texture that folks wouldn’t see most of the common dings and scratches that occur on a daily basis to all floors in any home (yes, your home too). How did I propose to accomplish this? 

First of all, I started with premium Strand Bamboo.  Trinity Bamboo’s Strand Bamboo flooring uses some of the hardest Strand Bamboo in the world.  In November 2016 we received updated ASTM D1037-12 Janka Test Results from Benchmark International, a lab in Eugene, OR, specializing in the testing of Wood, Concrete, and Steel products. If you’d like to read the original report yourself, you can download it from the Downloads section of at testing measures the force required to push a .444" steel ball .222" (half-way) into a sample. The greater the force required to push the ball in half-way, the higher the Janka rating. For perspective, Northern Red Oak has an average Janka rating of 1290 and North American Hard Maple has an average Janka rating of 1450. Trinity Bamboo performed six tests on our Natural Solid Strand Bamboo flooring and six tests on our Carbonized Solid Strand Bamboo flooring (If you are comparing Trinity Bamboo to our competitors, note how many tests some of our competitors performed (if you can even download or view them).  Trinity Bamboo's Strand Bamboo received the following average results: Natural Solid Strand Bamboo Janka average of 3780 and Carbonized Solid Strand Bamboo Janka average of 3646. These are really-high average values.  What this means to you is that, no matter what, your Trinity Bamboo Flooring will be exceptionally difficult to dent. 

Secondly, to help folks not see the inevitable scratches and dents, rather than sand Trinity Bamboo's flooring until it is mirror-smooth, I have chosen to highlight Strand Bamboo’s natural textures by hand-scraping and wire-brushing the flooring’s surface to create a sophisticated and predictable “antiqued” appearance.  The result of this treatment to the floor is a rare depth of richness and beauty, consistent and elegant, yet possessing the grain patterns and texture of old barn wood; used, loved, and lived on. 

Thirdly, to help prevent scratching and premature coating wear-through, Trinity Bamboo’s Strand Bamboo flooring is coated with premium UV Cured anti-scratch coatings and high-performance aluminum oxide barrier layers which help protect against coating wear-through.

When you combine the exceptional hardness of Trinity Bamboo’s Strand Bamboo with the antiqued surface finished with premium coatings, you have a floor that allows you to instantly start living on it.  No fears.  No worries.  Release the hounds, schedule a party, and enjoy your floor.

Greetings!  Thank you for taking a moment to visit Trinity Bamboo’s blog.  My name is Tom Goodham and I am the owner of Trinity Bamboo.  I will be updating this site frequently with a mixture of technical and whimsical musings, all (or mostly all) pertaining to Strand Bamboo Flooring and other bamboo products. 

Today, I would like to take a moment to talk about the Bamboo Flooring industry as a whole; why I’m in it, where it’s been, and where its heading. 

For more than a decade I have been part of a movement which believes that we can do things better; building premium Bamboo Flooring in a sustainable manner while providing our customers with some of the finest flooring (of any material) the world has to offer.  The missing link?  Price.  The fact is that in the world of premium flooring there are just too many people between the manufacturing side and the retail side of the industry. Walk into any flooring retailer, see what is available, look at the pricing for this material, and make your own decision.  I think that all people should be able to afford premium Strand Bamboo Flooring, and to make this possible, I started Trinity Bamboo.

I began my flooring career with Teragren Fine Bamboo in 2003, entering into the world of bamboo flooring straight from the world of coffee at Starbucks’ corporate office in Seattle.  It was a super exciting evolution from a global scale corporation to an environment where a small group of us were writing our game plan every day and our decisions had an immediate impact on the industry.  We were sustainability activists, riding the crest of the “Green” wave and carrying with us the enthusiasm and fervor of those who had figured out that it was possible to have fun and succeed in business by taking care of the planet, our workers, and our customers. 

Right around 2005 Strand Bamboo Flooring exploded onto the market and began to rule the world.  Why?  It is one tough product that is dimensionally stable, almost impossible to dent, and can be stained to look like almost any specie of hardwood.  How is it made?  Bamboo culms (the big green stalks) are cut down by hand, carried down a mountain, and then cut into six foot lengths.  These six foot sections are then split into small, slightly curved wedges, using a tool very similar in appearance to an apple slicer.  These bamboo wedges then have their outer green skin and inner paper-like lining removed.  The now roughly rectangular slats are crushed and dried before being immersed in a bath of phenolic resin (the adhesive).  This adhesive coated fiber is then removed from the adhesive bath, dried, and set aside for pressing.  Next, large platens (hot press method) or large rectangular molds (cold press method), are filled by weight with the adhesive coated fiber.  The molds are then heated under tremendous pressure, fusing the bamboo into a solid block.  This solid block is cooled, sliced to a working thickness, and then moisture balanced for many weeks until a moisture content of 7-10% is achieved. 

Is all Strand Bamboo of equivalent quality?  No. Why?  There is such intense market pressure to keep costs down that some manufactures use inferior glue, poorly prepared raw materials, and they do not moisture-balance the Strand Bamboo blocks for a long enough period of time.  As we have all learned at one point or another, you get what you pay for.

Where is this industry going?  Strand Bamboo is not going away any time soon.  We just keep making it better without significantly increasing the cost.  For those of us willing to pay for it, Strand Bamboo made using today's premium adhesives is absolutely amazing as evidenced by the formaldehyde emission verification test results Trinity Bamboo received from Berkeley Analytical.  For both Trinity Bamboo’s FloorScore® Certified Engineered and Solid Strand Bamboo flooring, the testing found our products' formaldehyde emission levels to be undetectable.  You can see the original reports here.  I have kids too…I get the importance of this.

So…what next?  How do you protect yourself as a consumer?  How do you make a wise purchasing decision?  Buy your Strand Bamboo flooring from a company such as Trinity Bamboo that prioritizes Quality, Integrity, and Value.
