          8.Curing: For grout mixed with acrylic latex admixture, allow grout to air cure. Protect tile installation and limit traffic until grout is completely cured.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          H.Epoxy Mortar and Grouting:
          1.Mixing: Mix with slow speed mixer at 150 RPM maximum. Do not mix at high speed or entrain air into mixture.
          a.Thoroughly mix resin component for 5 minutes minimum.
          b.Add hardener component and mix for 5 minutes minimum removing all lumps.
          ** NOTE TO SPECIFIER ** Delete if Hydroment Color-Poxy is used only as a mortar or adhesive.
          c.For colored grout applications, add colorant component to resin and hardener mixture. Mix until colorant is fully dispersed. Scrape down side and bottom of pail during process.
          ** NOTE TO SPECIFIER ** Delete if not required.
          2.Adhesive application:
          a.Apply epoxy adhesive to area no greater than can be tiled in 60 minutes.
          b.Apply thin coat of epoxy adhesive with flat edge of trowel to achieve mechanical bond to substrate. Comb adhesive with notched trowel of size recommended by manufacturer.
          c.Press or twist unit into combed epoxy adhesive.
          d.Beat unit into epoxy adhesive with rubber faced beating block to ensure maximum contact and bond.
          e.Field quality control: Periodically check back of unit for proper transfer and thickness:
          1)Interior applications: 95 percent minimum coverage.
          2)Finished mortar bed thickness: 3/32 to 1/8 inch (2 to 3 mm).
          f.Curing: Keep all traffic off installation for 24 hours minimum. Limit heavy traffic for 7 days.
          ** NOTE TO SPECIFIER ** Delete if not required
          3.Grout application:
          a.Preparation:
          1)Ensure unit is firmly bonded, clean, and free of dust and other contaminants.
          ** NOTE TO SPECIFIER ** Highly porous tiles and stone materials may require use of grout release agent or sealer to facilitate removal of grout haze. Include the following paragraph for release agent.
          2)Apply grout release agent or sealer to unit surfaces to facilitate removal of grout haze.
          3)Lightly dampen surfaces.
          4)Spread epoxy grout over unit with epoxy grout float. Work back and forth with 45 degrees angle to tile face. Completely fill joints. Remove excess grout with rubber float.
          b.Cleaning:
          1)Immediately perform initial cleaning. Lightly scour surface with a wet nylon scrub pad using circular motion. Clean grout residue from surface with damp cloth or sponge and rinse often.
          2)After epoxy grout has hardened in 8 to 16 hours, remove epoxy haze with cleaner as recommended by grout manufacturer. Wash off remaining residue with clean water. Complete final cleaning within 24 hours of installation..
