Recommended Substrates

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

  • Structurally sound, dry and smooth wall surfaces
  • Wood, plywood
  • Plaster
  • Dry concrete and concrete block
  • Brick
  • Gypsum drywall (Sheetrock)
  • Plastic laminate
  • Fiberglass paneling which has been lightly sanded
  • Metal and glazed surfaces that have been abraded
  • Cured and well-bonded paint on walls (paint must be cured for 30 days)


  • Vinyl wall coverings
  • Alcohol-resin adhesive residue

Application Instructions

INSTALLATION TIPS: Refer to Wall Base Installation System.

  • Condition area to be installed, materials, and adhesive at 65° F (18° C) or above for 48 hours before and 48 hours after installation.
  • Substrate must be smooth, sound, dry, clean, and free of dirt, wax, polish, loose paint, and all other foreign matter which may interfere in a good bond, including curing agents and sealers.
  • Glossy surfaces must be abraded for a proper bond.
  • Stir any liquid on the surface into the adhesive.
  • Use recommended trowel notching to spread adhesive on the back of cove base or directly to the substrate. Stay 1/8″ away from the top of the base to prevent adhesive oozing. (When using cartridges, apply beads uniformly spaced on the back of the cove base: two 1/8″ beads to the back of 2-1/2″ base, three beads to 4″ base, and five beads to 6″ base.)
  • Install cove base immediately.
  • Press firmly to the wall. To assure a tight fit, roll the cove base toward previously installed section.
  • Remove wet adhesive residue with a clean, white cloth dampened with soapy water. Use mineral spirits for dried adhesive residue carefully following warnings on container.
