Active & Reactive Acid & Water Base Stains | Petra Guard Coatings

Acid and Water Base Stains

We offer both acid and water base stains. Reactive and nonreactive are the two categories that concrete stain falls under. Reactive Stains (Acid Base) are acidic pigment solutions that react with the concretes lime content, forming a permanent bond with the concrete. Non-reactive stains (Water Base) are a water based acrylic stain which are formulated to penetrate the substrate surface and deposit their pigment in the open pores of the concrete. The stain is then sealed with an epoxy or urethane coating to help ensure that the stain does not get washed out and remains vibrant for years to come.
