1) Thickness of coats: Verify thickness as systems vary by manufacturer; approximate range from 5 to 6 mils (0.13 to 0.15 mm) to 150 to 250 square feet per gallon (52.76 to 87.93 square meters per liter). 2. Body Coat: a. Resin: Epoxy or Urethane. b. Formulation Description: 100 percent solids. c. Application Method: Varies by manufacturer; hand or power troweled. 1) Trowel application: a) Thickness of coat: Verify thickness as systems vary by manufacturer; approximate from 3/16 inch or 1/4 inch or 3/8 inch (4.76 to either 6.35 mm or 9.5 mm). b) Number of coats: One. d. Aggregates: Verify amount per thickness as systems vary by manufacturer: 1) Marble (#1 size maximum), glass, or granite chips or, colored resilient aggregates, acrylic, or other approved materials. 3. Grout Coat: a. Resin: Epoxy. b. Formulation Description: 100 percent solids. c. Application Method: Varies by manufacturer. by red rubber squeegee or spring-steel trowel. 1) Apply to rough ground mortar coat to completely fill all voids. 2) Thickness of coat: Verify thickness as systems vary by manufacturer; approximate range from a minimum of 8 to 10 mils (0.2 to 0.25 mm) to a maximum of 400 to 500 square feet per gallon (140.65 to 175.81 square meters per liter). 4. Seal Coat/Top Coat: a. Resin: Single- or multi-component Urethane. b. Formulation Description: 100% solids. It shall have a pH factor between 7 and 10 and shall be a penetrating type specially prepared for use on terrazzo. It shall not discolor or amber the terrazzo and shall produce a slip resistant surface. Flash point of sealer shall be a minimum of 80 degrees F (26 degrees C) when tested in accordance with ASTM D 56.
