Installations should not be below grade level.

The flooring should be inspected by the installer or contractor for defects prior to installation. Carefully examine the flooring boards for color, finish and quality using reasonable selectivity. Hold out or cut off pieces with glaring defects, whatever the cause. Flooring that is installed is presumed to have been accepted.

Flooring boards can either be nailed or glued onto the sub floor. The sub floor must be smooth and flat and free of dirt. The moisture content of the sub floor must not exceed 14% and be more than 4% above or below the moisture content of the flooring to be installed. While installing pre-finished bamboo flooring, you should nail it at a 45 or 50 degree angle; you should make a hole beforehand if the nail size is too big because it may crack the tongue; you should use a oil based glue or a glue with low water content to glue the floor. If you use high water based glue, it may make the flooring swell because the floor absorbs the water from the glue.

The flooring should be “racked out” so as to distribute color variations randomly (or otherwise, to the client's satisfaction) within the room. The flooring is a natural product and color variations are to be expected. Samples of particular flooring products are available upon request.

Make certain that sufficient expansion space is left at the perimeter of the installation. In climate areas where the humidity of the room varies seasonally very little, a minimum expansion space of ?” is recommended. In areas where humidity variation is high from season to season an expansion space of ?” is recommended. Bamboo hardwood flooring behaves in a fashion similar to hardwoods; your local professional installer will be your best guide as to climatic variations common in your area.

Flooring should be installed in conditions representative of conditions expected during occupancy of the space. Flooring should be unpacked and allowed to acclimate in such conditions for a minimum of 72 hours with a preferred recommendation of one week to ten days.
