Surface must be level before application, as use of Safecoat 3 in 1 Adhesive will not substitute for a leveling compound, especially over surfaces such as concrete. All substrates to receive adhesive and overlays must be sound and intact. Any loose areas should be repaired or anchored to produce a firm footing for adhesion. All surfaces must be cleaned of any grease, oils, dust, dirt, wax, unsound prior adhesive and other foreign materials. Washing with a low odor, not toxic cleaner like SafeChoice Cleaner is recommended. Best results can be obtained if non-porous surfaces are dry and stable prior to application. Porous surfaces will benefit from a coat of Safecoat Safe Seal prior to application of 3 in 1 Adhesive (for maximum adhesion, even non-porous surfaces benefit from the application of a thin coat of Safecoat Safe Seal to the substrate and if possible the surface to be adhered – for example the back of the tile - before spreading adhesive and laying the tiles). 3 in 1 can be applied over slightly tacky SafeSeal. Use adequate ventilation. Refer to flooring manufacturer’s specific recommendations. Adjust the temperature of the area to be installed, adhesive, and flooring to at least 65°F (18°C) or above for 48 hours before, during, and 48 hours after installation.
Always have adequate ventilation. Stir any liquid on the surface into the adhesive. For carpeting, cementitious and ceramic tile, application should be made with 1/8” or larger notched trowel (commonly v- notched for walls and square notched for floors, but consult your installer). A 3/16” notched trowel should be used for wall tiles. All other applications require 1/16”, including residential felt-back rotovinyl sheet flooring. Due to rapid cure do not spread the adhesive over areas larger than 16-20 square feet.Allow adhesive to set up or “tack-up” for a few minutes (typically not more than 10-15 depending upon temperature and humidity), and then insert tiles into mastic. Maintain a wet, tacky surface during installation of the tile. Do not allow adhesive to skim over. If a film forms or adhesive skims over, or sets up so that it is no longer sticky, scrape all adhesive off the surface and reapply. Allow 24 hours for 3 in 1 Adhesive to cure out before opening to traffic or for any further surface filling. A trial application is recommended to assure proper adhesion can be obtained. Testing is particularly important for parquet and wooden floor material, which varies considerably in consistency and may have a tendency to warp. Again, seal the bottom of the material with Safecoat Safe Seal to help provide a moisture barrier. Roll flooring in both directions with a 75–100 lb. roller and seal seams as recommended by the flooring manufacturer. Stiff carpets/sheet goods should be rolled again after 2 hours. Restrict heavy traffic for 24-48 hours. Protect adhesive (specifically carpet installations) from exposure to water from cleaning and other sources for a minimum of 30 days after installation
