Recommended Substrates

Will bond to all substrates listed below but refer to flooring installation system for specific installation recommendations:

DO NOT USE OVER: Concrete with excessive moisture and/or alkali; existing cushion-backed resilient flooring; substrates treated with fire-retardant chemicals, fungicides, preservatives, release agents, adhesive removers, sealers, curing compounds or other incompatible treatments

Application Instructions

  • Condition area to be installed, adhesive, and tile at 65° F (18° C) or above for 48 hours before, during, and for 48 hours after installation.
  • Subfloor must be smooth, sound, dry, clean, and free of dirt, wax, polish, paint, and all other foreign matter which may interfere in a good bond, including curing agents and sealers.
  • Moisture testing must be performed on all concrete slabs regardless of their age or grade level including areas where resilient flooring has already been installed. Moisture testing should be conducted with the area or building at service conditions, i.e. fully enclosed, weather-tight and with permanent or temporary HVAC in operation. In general, moisture testing should be conducted on concrete surfaces that exhibit the final prepared stage before the installation of the flooring material and before installation of smoothing or leveling compounds.
  • Stir any liquid on the surface into the adhesive and full spread using the recommended trowel notching.
  • Allow adhesive to set open until dry to the touch, approximately 30 to 90 minutes. When dry to the touch, the adhesive will be tacky with no transfer to fingers.
  • Install and fit all tile within 24 hours. Working time will vary based on job conditions, substrate, temperature and humidity.
  • Most resilient commercial tile does not need to be rolled upon completion of the installation. However, residential tile and certain specialty tile must be rolled – refer to Tile Installation System for recommendations.
  • Remove wet adhesive residue using a clean, white cloth dampened with soapy water. Use mineral spirits for dried adhesive residue carefully following warnings on container.
  • Do not wet wash or strip tile for at least five days after installation.
