Acrylic concrete stains are non-reactive, semi-transparent stains with adhesive properties for creating a bond with porous concrete.
In order for acryic stains to work properly and last, the concrete surface must open (porous). If you apply them to a super slick, hard-troweled surface, or concrete that already has a coating, they won't last. Concrete can be made more porous by grinding, sanding, or acid etching.
You can use these stains on interior and exterior surfaces including:
They are resistant to UV rays, foot traffic, heat from vehicle tires, moisture, mildew, acids and alkalis as well as mother nature.
For do-it-yourselfers, water based stains are non-toxic and easy to apply making them much more user friendly. Application can be done by rolling, brushing, spraying, sponging, etc.
These stains also come in a wide selection of colors, more than that of acid stains. You can also use blending techniques to create your own unique marbling effect or use an object such as a sponge to make patterns with accent colors. But whether you want a simple color or multiple color patterns, acrylic stains will make your dull concrete much more appealing.
You can also perform simple scoring techniques to further enhance a concrete surface. Use your imagination to create designs and patterns.
It's important to know that there are many products that claim to be "concrete stains" and, in my opinion, many are not. There's a difference between coatings and stains. Coatings lay on top of the surface whereas stains penetrate the surface. If it's not thin and can't penetrate the tiny pores of concrete, then it's not a stain.
