CONSIDERATIONS
SURFACE PREPARATIONSteel Surfaces should be blasted to an SSPC SP6 commercial gray metal blast. Immersion applications should be blasted to an SSPC SP-5 white metal. Grind flat all burrs, weld seams, round sharp edges. Freshly blasted surface can be primed with this material. Concrete surfaces should be abrasive clean to remove soft surfaces, paint, sealers, and any other contamination. Prime with Epoxy.com #12 primer or neat #636, or #637. INSTALLATIONMix 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. | |||||||||||||||||||||||||||||||||||||||||||||
