The Types of Concrete Stains and How They Work
When you go shopping for concrete stain, you’ll find two types of products. Each one colors concrete differently and offers a different look.
Example of an acid-stained floor
A traditional acid-based concrete stain reacts chemically with the concrete surface to produce variegated, translucent color tones and attractive marbling effects. A true acid-based concrete stain contains metallic salts that react with the concrete's lime content. Once the chemical reaction takes place, the stain forms a permanent bond with the concrete and won't chip off or peel away.
Water-based stain in ocean blue
A newer category of concrete stains are water-based acrylics. These products don't rely on a chemical reaction to impart color. Instead, they work more like a paint by depositing their pigment particles in the pores of the concrete. These stains come in a much broader palette of colors than acid stains, and they are easier to apply. But their color effects tend to be more opaque and more uniform.
