SP-11 is a black, single-component epoxy primer incorporating state-of-the-art water-based technology to produce an extremely versatile product that penetrates and seals porous substrates. It is effective at increasing the bond of silicone topcoats to a variety of surfaces and will also help to “solidify” punky or chalky surfaces.
