Material should be thoroughly inspected prior to installation.  Any materials installed with obvious defects will not be warranted.  Note: Color variation is not considered a defect.  This is a natural product.

 Installing bamboo over concrete:

• When installing on a concrete slab, the slab must be at least 60 days old. 

• The moisture content of the concrete slab must not exceed 3 pounds per 1000 square feet in a 24 hour period. A Tramex reading of 3 or more always means a calcium chloride test must be used to determine moisture content.

• Use a calcium chloride test is the only affirmative way to test.  Refer to the National Wood Flooring Associations hand book if you need further information on procedures to test floors for moisture. 

• Press wood into adhesive. Occasionally check the back of a board for adequate adhesive transfer.

• Avoid foot traffic for 24 hours after installation.

• Do not cover floor for 48 hours.

• Write down and keep the moisture test results for future reference. 

 Glue down method:

We require using moisture cured urethane adhesive.  Follow the recommended trowel size for bamboo from the glue manufacturer.  Planks should be started square with the room and parallel to its longest dimension.  Leave at least a 5/8  inch around the walls and obstacles for expansion.  Use a chalk line to mark the initial 3 rows.   Ensure starter rows are firmly in space by wedging or face nailing. 

 
Confirm the area to be installed, adhesive and flooring are at 65°F (18°C) or above for 48 hours before, during and 48 hours after installation. Subfloors must be flat within 3/16. in 10 ft. or 1/8. in 6 ft. Fill low spots with a Portland cement-based leveling compound with a minimum compressive strength of 3000 psi and allow to dry. For commercial applications, the compressive strength should be a minimum of 3500 psi. Subfloor must be smooth, sound, dry, clean and free of excessive moisture and/or alkali. Remove dirt, wax, polish, paint, and all other foreign matter which may interfere in a good bond, including curing agents and sealers. All loose subfloor boards must be renailed or properly bonded to create a sound subfloor. Moisture test results must not exceed 3 pounds/1000 sq ft/24 hours. A Tramex reading of 3 or more mean a calcium chloride test must be used to determine moisture content.
