Acrylic Concrete Stains and
Soy: An Alternative to Acid Stain

Concrete acrylic stains can be used to create accents or glazing effects like faux marble or stone. When contractor and instructor Bob Harris was in Italy this year, he took inspiration from some of the historic Venetian floors, which he recreated with the color-upon-color process that is a large part of his decorative concrete business. This layering is possible only with water-based stains, Harris says.

Many applicators like to work with acrylic stains simply to avoid using acid stains, which generally give off more odor, require more cleanup, and provide less margin for error. Another factor on the plus side for acrylics is color selection, according to many contractors and dealers, including Doug Bannister, owner of The Stamp Store in Oklahoma City, which produces a line called SS Rainbow Stain System. When acid staining, color selection is limited by the concrete canvas you have to work with, Bannister says.

Another attractive feature of these stains is cost. They generally cost less to buy and apply than acid stains. The cost, combined with simple application methods and a forgiving nature, make acrylics a popular alternative to acid staining. Experts in acrylics say this is all true. But if you are looking to cut corners, don't do it on prep, sealing or maintenance. "You almost need to be an extremist when it comes to preparation," Harris says.

Like any topical coating, stains require a properly profiled concrete surface. If the surface isn't mechanically and chemically ready to receive, the coating is likely to fail, says Chuck Brunner of Smith Paint Products.
