Surface Preparation
All surfaces must be clean, dry, free of dirt, dust, grease, oil, loose paint, wallpaper, and residues of old adhesive, or any foreign matter which might impair adhesion where TEC® Skill SetTM Premium Tile Adhesive is spread. Painted enameled walls and floors must be thoroughly scored or sanded to insure a bond to the original base wall or floor. Do not sand any floors or adhesives that are known or suspected to contain asbestos. Installations where concrete is damp or the concrete is subject to moisture vapor emissions can fail.

The adhesive, tile, and room should be maintained at a minimum temperature of 60°F for 24 hours prior to installation. The minimum 60°F temperature must be maintained during the entire installation, and for a minimum of 48 hours following. Use a 3/16” x 5/32” V- notched trowel for installation of tile up to 6” x 6”. For tiles larger than 6” x 6”, use a 1/4” x 1/4” x 1/4” square-notched trowel. For tiles 12” x 12” to 20” x 20”, use a 1/4” x 3/8” x 1/4” square-notched trowel.

Only apply the amount of adhesive to surface that can be tiled over in 15 minutes. DO NOT SET TILE IF SKIN HAS FORMED ON THE ADHESIVE. This time will vary with the temperature, humidity, and the substrate. Apply the adhesive to the substrate first with the flat side of the trowel. Then comb with the notched side of the trowel in one direction. Firmly press tiles into the adhesive and move them perpendicularly across the ridges. Do not slide tiles against each other. Periodically remove and check a tile to assure complete coverage.

Cure times will vary with size and porosity of tile and porosity of floor (porcelain tiles take considerably longer to cure), humidity and temperature (cooler temperatures will extend set times). Typical floor installations take longer to cure. No traffic is permitted on tiles prior to curing. Grouting may begin once adhesive is firmly set up. Up to 6” x 6” wall tiles require wait time of 6 hours or longer. Over 6” x 6” tile or any floor tile application requires a least 12-24 hours. Check to determine readiness by trying to twist the tile and see if it moves. If it does, additional cure time is required. If the tile won’t twist but you hear a wet suction sound when the tile is stepped on, additional cure time is also required. The use of TEC® Skill Set™ brand grouts is highly recommended.

Full cure takes at least 48-72 hours depending on conditions.

For glass tile, refer to manufacturer's specifications. For marble and granite installations, test in an inconspicuous area as discoloration may occur. Most discoloration disappears after 30 days. For proper curing, do no abut the marble tiles together.

While adhesive is still fresh, clean tools, hands, and excess material from face of tile with warm soapy water. If adhesive has dried, use acetone or mineral spirits to remove.
