Application Guidelines

Suitable Substrates:
Refer to the flooring manufacturer’s specific recommendations for suitable substrates. Porous: Concrete, well-bonded cementitious underlayments, APA grade underlayment plywood (untreated) and radiant-heated subfloors where temperatures do not exceed 85°F (29.4°C) on all grade levels. Also can be used over well-bonded, properly primed gypsum underlayments (above-grade only). Non-porous: Ceramic tile, terrazzo, marble, certain epoxy coatings and existing well-bonded resilient flooring (not perimeter bonded or cushion-backed). Please note that all substrates must be sound, solid and well-bonded.
Subfloor Preparation:
All substrates must be clean, dry, structurally sound, properly cured and free of dirt, oil, paint, old adhesive, wax, sealers and curing agents. General scouring with 20 grit or #3 1/2 open-coat sandpaper will remove most compounds. All loose materials must be vacuumed from the surface after scouring. The subfloor must be flat to a tolerance of 3/16” in a 10’ radius. Grinding concrete floors is preferred over the use of filling compounds. If filling/flattening compounds are used, they must be Portland-based cementitious material and have a compressive strength equal to or greater than 3000 psi when cured. Moisture level in concrete subfloor will fluctuate. Any cementitious material used must be rated for the highest moisture content possible. Consult the cementitious material manufacturer’s application directions. Use of adhesive over lightweight concrete and all gypsum-based materials requires the use of an approved concrete primer prior to application of adhesive.
Floor Covering Recommendations:
Vinyl composition tile (VCT), foam backed hardwood parquet.
Installation Recommendations:
Franklin 920 may be applied by roller, brush, trowel or airless adhesive gun. On smooth surfaces, use a 1/32" U-notch trowel at the rate of 250 square feet per gallon. On rougher surfaces, use a 1/16" square-notch trowel at the rate of 150 square feet per gallon. By roller, brush or spray, apply at the rate of 135 square feet per gallon on smooth surfaces and apply heavier on rough surfaces. Minimum open time is 20 minutes, or until adhesive becomes nearly clear and no longer transfers to the finger when lightly touched. Set tiles in place carefully because they will not slide. Roll within 12 hours with a heavy linoleum roller. Restrict heavy traffic for 24 hours.
Cleanup:
Allow adhesive to dry well before exposing installation to cleaning. Use water to remove adhesive spots and clean tools.
Limitations:
SUBFLOOR MOISTURE CHECK & ALKALI Concrete subfloors should be tested for moisture prior to installation. Moisture levels cannot be greater than 7 lbs./1000 sq.ft./24 hours on a Calcium Chloride Test (ASTM F1869), or relative humidity (RH) of 90% or less when tested with an in situ probe (ASTM F2170). Alkali needs to be checked and should be in the range of 5-9. When installing directly over wood subfloors the moisture content of the subfloor should be 13% or less.

Do not use over high alkaline concrete (over 9.0 pH). Do not use over or under solid vinyl tile or sheets goods. Do not store below freezing. Use in well-ventilated area. Warranty covers subfloor moisture resistance but does not cover damage from flooding or other surface moisture contamination.

CAUTION: Do not sand, scour or abrade any material that is suspected of containing asbestos fibers. Asbestos is known to cause cancer. Federal law requires that asbestos be handled by a licensed and certified hazardous materials contractor.
