Epoxy.com Product #845 Epoxy Penetrant & Prime Coatis designed for less than ideal surface preparations.
However, performance will be improved as surface preparation improves. All oil/grease, contaminants, loose rust, loose scale and unsecured old paint must be removed. Remove all contaminants by means of low/high pressure water blasting. Concrete surfaces new or free from contaminants should be brush blasted to remove surface laitance.
Combine (2) two parts "A" to (1) one part "B" by volume in the quantity desired and mix with a low speed drill for 3-5 minutes. Scrape sides and bottom to ensure thorough mixing. Do not thin the Epoxy.com Product #845.
Epoxy.com Product #845is a two component product supplied in 3 gallon and 15 gallon kits. The pot life of the mixed material is 3 hours at 77° F (25° C) . Higher temperatures will reduce working life of the coating; lower temperatures will increase it.
Epoxy.com Product #845 Epoxy Penetrant & Prime Coatcan be applied by conventional air spray, brush or roller. Epoxy.com is designed to be applied in one coat at 1.0 to 1.5 mils .
A Graco #700 or #800 air spray gun with suitable needle/nozzle and air cap combinations will work best. To minimize over spray, use low air pressure and pot pressure, 5 to 10 psi (0.3 to 0.7 bars) Airless pump application is not recommended.
Epoxy.com Product #845 is low in viscosity. It should be applied in one thin, wet coat sufficient to completely cover and penetrate to the steel surface. Do not apply heavy coats. Clean up application equipment withappropriate solvent MEK xylene Acetone.
Apply one coat of Epoxy.com Product #845 at 1.0 to 1.5 mils - allow overnight cure. An additional coat may be required for very porous surfaces. After overnight cure, Epoxy.com Product #845 may be coated if still tacky. Epoxy.com Product #845 may be top coated with a wide range of top coating systems.
