INSTALLATION INSTRUCTIONS

DIRECTIONS:
Refer to acoustical tile manufacturer’s specific recommendations. Condition the area to be installed, adhesive and ceiling tile at 65°F (18°C) or above for 48 hours before, during and 48 hours after installation. Test painted surfaces to assure compatibility by adhering 3 or 4 tiles to painted surface. Wait 48 hours. If the paint softens and/or releases from the substrate or the tile does not adhere to the paint, the paint must be removed before beginning installation. We cannot assume responsibility for failures related to paint releasing from the substrate or adhesive releasing cleanly from the paint.

  • Stir any liquid on the surface into the adhesive.
  • Adhesive will not properly adhere to tile with dusty backs, and a failure may occur. To assure a good bond, prime all tile with this adhesive before daubs of adhesive are placed on the tile.
  • Use a pointing trowel or putty knife to apply daubs of adhesive, each about walnut size (approximately 25 grams/weight), about 3" in from the corners of tile. As shown under Trowels/Coverage”, apply four daubs to 12"x12" tile and six daubs to 12"x24" tile.
  • Place tile against substrate applying even pressure with both hands. Press tile into place immediately, with a vibrating back and forth motion, exerting uniform pressure on each daub.
  • When tile is in position, daubs should be 2-3/4" to 3" in diameter and 1/8" to 3/16" thick. Too much or too little adhesive will reduce the initial strength of the adhesive, and a failure may occur.
  • When installing tongue and groove tile, take special care to avoid disturbing daubs of adhesive on tile already installed. Place tile in approximate position, and slide back and forth slightly with uniform pressure of the hands to obtain good adhesive contact. When joints are at same level, slide tile into position. Do not put tongue in groove first, then push up opposite side of new tile, as this will release adhesive on tile already in place.
  • Once the tile is in place, do not pull down or bend it to place in the next tile. The “spring load” will cause the adhesive to release.
