AMERLOCK SEALER CURE 1-GA|Amercoat's Amerlock Sealer is a penetrating sealer for marginally prepared steel and aged coatings. Its low viscosity and excellent wetting properties allow it to penetrate rust and discontinuities in existing coatings, which in turn improves adhesion of subsequent topcoats. It has excellent resistance to corrosive environments. Amerlock Sealer can also be used as a concrete primer/sealer, and as a concrete curing compound. It must be applied either immediately after pouring and finishing, or as soon as the forms are removed, and the concrete must cure at least 14 days before topcoating. Amerlock Sealer is a 100% solids epoxy sealer.
