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.

Pre-Installation

General considerations:  Area to be installed, temperature and humidity must be brought to normal living conditions for at least 48 hours before installation and maintained at this level during and after installation.  Flooring and all supplies should be allowed to acclimate on site for 48 hours before installation.  The bamboo should be unpacked and stacked in small piles during this time.  There should be no more than a 3% difference between the sub floor moisture content and the bamboo flooring.  The wood subfloor moisture level must not exceed 12%.  If 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. 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.  A MOISTURE TEST MUST BE PERFORMED AND RECORDED FOR WARRANTY.

 Floor Layout:  Decide which way to lay the flooring: gluing method or nailing method.

The flooring may be nailed or glued down over wood sub floors, or glued directly to a concrete floor.

 Preparation

The sub floor surface must be smooth, dry and clean of all dirt, wax oil, paint, curing agents, and any other contaminants that would interfere with the adhesive bond.  Wood sub floors must be sanded level prior to new installation.  Concrete sub floors must have all crack and holes filled with a cement-based patching material.

Installation

Nail down method:

Planks should be started square with a room and parallel to its longest dimension.  The beginning three rows should be marked with a chalk line leaving 5/8 inch(thickness of one board) expansion space away from all walls and obstacles.  Ensure starter rows are firmly in place by wedging or face nailing.  Once initial rows are secure, forth and further rows shall be blind nailed directly above tongue at a 45-50 degree angle to the face.  Nails should be spaced at 10-12 inch intervals with a minimum of 2 per piece, 3 per full length.

 Glue down method:

We require  using a 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.  Once the rows are cut and test laid, apply the adhesive in a wet-lay method.

Apply adhesive to the sub floor with the adhesive manufactures recommended trowel size. Follow the glue manufactures instructions for drying times.  Remove all excess adhesive as you install,  you will not be able to remove it once it has dried.  Do not use water to remove the wet adhesive.
