Hillyard, Concrete Defense® Repel® Penetrating Seal, 1 gal Bottle

A unique, non-silicone formula that provides a durable, subsurface, transparent protective barrier against water and oil on porous surfaces such as concrete and stone. In colder climates, when water penetrates concrete and stone surfaces, it freezes and expands, creating the environment for chipping and cracking. Water and stains that would normally penetrate deep into porous surfaces are now kept close to the surface reducing the chance for water damage and stains. Treating concrete and stone installations with Repel ensures that surfaces are kept to a high standard of appearance with reduced maintenance efforts.
