Duratop Primer WB

Duratop Primer WB is a water-based epoxy primer that treats and seals surfaces in preparation for later waterproofing. It can be used on both damp and dry surfaces and is especially effective for priming new concrete as it penetrates the surface, forming a strong, waterproof bond and allowing for easy overcoating. Duratop Primer WB is a twin pack, water-based epoxy primer of brushable consistency for clean cementitious surfaces.
