As part of the Hillyard Concrete Defense® system, Concrete Primer is a safer floor prep alternative and eliminates typical steps like acid-etching, grinding and shot-blasting, making it easier to get professional results with in-house floor finish expertise. The innovative proprietary acrylic formulation maintains a slight tack to adhere to both the surface and top coat seal. Concrete Primer cures with the top coat to provide a durable, bonded protective coating system.
