INSTALLATION INSTRUCTIONS

DIRECTIONS:
Refer to flooring manufacturer’s specific recommendations. Condition the area to be installed, adhesive and flooring at 65°F (18°C) or above for 48 hours before, during and 48 hours after installation. Floor must be sound, smooth, dry, clean and free of excessive moisture or alkali. Remove dirt, wax, loose paint and all other foreign matter that would interfere with a good bond such as curing agents and sealers.

  • Stir any liquid on the surface into the adhesive.
  • Full spread adhesive using recommended trowel. NOTE: Recommended trowel sizes are guidelines only, and are minimum requirements. Rough, porous concrete and heavily textured carpet backings may require deeper notches. A 100% transfer of adhesive into the carpet backing, while maintaining full coverage of the substrate, must be obtained.
  • No open time required over concrete. For all other substrates, allow adhesive to set open for 10-20 minutes. Do not let adhesive skin over.
  • After appropriate open time, install floor. Within 40 minutes, cut, fit and reposition as recommended by the flooring manufacturer.
  • Roll floor in both directions with a 75-100 lb. roller and seal seams as recommended by the flooring manufacturer. Stiff carpets should be rolled again after 2 hours. Restrict heavy traffic over carpet for 24-48 hours.
  • Protect carpet from exposure to water from cleaning and other sources for a minimum of 30 days after installation.
