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!

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.

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!

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.
