Mix 2 Parts Resin (A) to 1 part Hardener (B) by volume, adding the B to the A. Mix with a mixing stick or low speed drill with a mixing paddle. Do not thin.
Apply by brush, roller, or airless spray. To brush use medium to stiff bristle brush with a bristle quality that does not pull out into the coating. To roll use a 1/8 to ? inch nap roller on concrete. To plural spray use .019 - .021 tip at 2,000-2,500 P.S.I. Heat "A" component to 120 ° F. Heat "B" to 110° F. To spray by airless spray, use .019-.023 tip at 2,000-2,500 p.s.i with in line heater only (Caution: Short pot life). It is not recommended that you use conventional spray. Apply two coats at 10 mils thick each for dry applications. A third coat for a total thickness of 30 mils recommended for immersion applications.
Keep material between 55° F and 95° F. Maintain a substrate temperature between 45 and 105° F. The difference in temperature between the substrate and the coating should never exceed 10° F
For best chemical and temperature resistance force cure for 12 hours at 150° F, 6 hours at 250° F.
Application thickness should be 20 mils (.51mm) / coat. For immersion service use 2-3 coats.
