SOLID STRIP BAMBOO FLOOR INSTALLATION

PREPARATION

Prefinished solid strip flooring is best applied by nailing, stapling, or gluing planks to a wood subfloor. Gluing directly to a concrete slab may be done at or above grade. Do not install below grade. Flooring may also be applied over radiant floor heating systems. Flooring should be allowed to acclimate on the job site three (3) days. The acclimation period should be at expected normal room temperature and humidity levels before and after installation. Damp or cold conditions before installation should be avoided. The maximum difference in moisture content between the subfloor and the flooring material should be no more than 3 percent. The amount of movement depends upon the temperature, moisture content of the flooring and subflooring (wood moves as moisture content rises and falls) and the dimensional stability of the material. Gaps in the floor may come and go seasonally or due to temperature changes. Humidity levels should remain between 40% and 60%.

Because bamboo is a natural fiber, variations in color naturally occur. Each box should be inspected for differences in color and staggered throughout the floor.

SUB FLOORS

Wood sub-flooring surfaces must be clean, dry, and if gluing the flooring, free of contaminants that would interfere with an adhesive bond. Sub-floor or underlayment nailing surface also must be level and smooth prior to installation of flooring. For optimal installation, we recommend 3/4 inch CDX plywood as nailing substrate or for a glue application. Or use 5/8" CDX ply for 12 inch on center and 16 inch on center floors and 3/4 inch CDX ply for 24 inch on center floors. Optimum sub-floor is 1-1/8" plywood over joists at 16 inches on center. Concrete sub-floors must be tested for moisture and a vapor retarder such as 6 mil polyethylene film should be placed in crawl spaces. We recommend using the Calcium Chloride Test Method. Flooring must not be installed if vapor pressure exceeds 3 lbs. per 1000 square feet in 24 hours. Concrete should be checked for flatness prior to installation and low spots and voids filled to a minimum of 3/16" in a 10 foot radius or 1/8" in a 6 foot radius, and high spots ground to surface. Surface must be smooth and free of debris, oils, grease and solvents. Slabs younger than 60 days are generally too wet for flooring installations

NAIL OR STAPLE DOWN

Flooring should be square with the space and perpendicular to the joists. Leave 1/2 inch expansion space from base plate or wall. Starter rows should be held firmly in place by wedging or blind nailing. Once starter rows are secure, additional rows should be blind nailed directly above the tongue at a 45-50 degree angle to the face. Fasteners should be spaced at 10 to 12 inch intervals per plank. Nails or cleats should not be placed closer than 6 inches from the end of planks to prevent splitting

GLUE DOWN

If the glue down application is the method chosen, we recommend using a premium wood flooring adhesive. Flooring should be square with the space and run perpendicular to the joists. Leave 1/2 inch expansion space from base plate or wall. Starter rows should be held firmly in place by wedging or blind nailing. Once starter rows are secure, use adhesive in a Wet-Lay or Walk-on-Work method of installation. If gluing down to Gyp-Crete, follow Maxxon® Corporation instructions at www.maxxon.com.

Wet Lay Method: Apply adhesive to substrate with suitable trowel. Immediately place flooring onto "wet" adhesive.

Walk-on-Work Method: Apply adhesive to substrate with suitable trowel and allow it to develop tack (may take an hour or more depending on temperature and humidity). Install flooring onto "tacky" adhesive. Immediately roll finished installation with 150# roller. Room, flooring and adhesive should be conditioned at room temperature for 72 hours before and after installation.

ON FLOORS WIDER THAN 20' TO MINIMIZE EXPANSION

On floors wider than 20 feet, to minimize expansion, more or less spacing may be needed depending on geographical area, interior climate control and time of the year. In some areas, additional spacing may not be necessary. Where spacing is required, use a washer or removable spacer to leave additional space every few rows and/or start in center of room and work out to both sides."

RADIANT FLOOR

A radiant floor should not produce temperatures over 85 degrees Farenheit. The radiant heat system should remain in operation after installation. It should be noted any wood flooring, as well as bamboo flooring, will expand and contract due to temperature changes. The maximum difference in moisture content between the subfloor and the flooring material should be no more than 3 percent. The amount of movement depends upon the temperature, moisture content of the flooring and subflooring (wood moves as moisture content rises and falls) and the dimensional stability of the material. Gaps in the floor may come and go seasonally or due to temperature changes. When choosing an installer for application over radiant heat, look for members of the Radiant Panel Association.
