Due to the density of strand woven bamboo flooring, we recommend only using a high PSI, high quality 18 gauge pneumatic nailer, such as a Primatech Q550 ALR or Powernail 50P Flex. These nail guns require an air compressor. You must use an 18 gauge cleat, as larger cleats will cause dimpling. Staple guns will not work on strand woven floors. When nailing down a floor we typically recommend you first lay 15 lb felt paper.
For moldings installation we recommend a Bostich Porter 23 gauge micro nailer or similar gun.
For all nailers, make sure cleats and nails are set properly before continuing to the next row, as failure to do so may result in goosebumps/dimpling. You may need to try several pressure/PSI settings before finding a setting that will work – test on sacrificial planks. Ensure the connector hose, seal, and air compressor are fully functional and have no tears or defects.
If you do not use the correct nail gun or cleat size, you may get dimpling in your floors. Read this important document about goosebumps and dimpling in strand woven bamboo.
NAIL GUN PRESSURE TOO HIGH: ALWAYS practice on a few planks to ensure the correct PSI setting on the nail gun. If the pressure is too high the nail will split the plank. When using the mallet always use small, light taps - as opposed to large, forceful taps – this is the best to get a snug fit.
NAIL GUN PRESSURE TOO LOW: If the PSI is too low you will end up with dimpling (“goosebumps”) on the face of the floor. Always inspect for dimpling from a low angle and with backlighting after installing the first two rows, because it’s difficult to see when standing directly over the area. It is the responsibility of the installer to check each row after it has been nailed down to ensure all cleats are sufficiently embedded in the planks so they don't cause dimpling in the finished floor upon fastening successive rows.
NAIL GUN PRESSURE JUST RIGHT: You will know that the pressure is just right when the cleat is flush or slightly below the surface of the tongue.
Tongues are slightly splitting – that is okay!
When nailing down extremely dense hardwoods like strand bamboo and eucalyptus there is a chance that the tongue on the planks will crack or split when the cleat is driven in. As long as less than 30% of the cleats have splitting around them, and the splitting is minor, this is perfectly normal and is not considered a defect (your floor will still be covered under the warranty if this happens) as the cleat is still firmly driven into the rest of the board keeping it securely in place. When splitting is happening try to use less force when striking the nailer with the mallet. Below is an image showing acceptable splitting, if occurring on less than 30% of the planks.
