Learn about concrete stains and the advantages and limitations of each type, from water-based acrylics to acid-based chemical stains, and what to consider before choosing… For many years, decorative concrete contractors have been using acid-based chemical concrete stains to achieve rich, earth-toned color schemes resembling natural stone, marble, wood, or even leather. But today, contractors are no longer limited to earthy shades. And in some cases, these newer stain products are easier and safer to apply.
Concrete stains become a permanent part of the concrete. They're known for their durability and long-lasting color because concrete stains will not fade, chip, or peel off.
Concrete stains are also known for their translucent color. Because of the various conditions of concrete surfaces, concrete stains react differently creating one-of-a-kind color and patterning.
Because they penetrate the concrete surface, most acid- and water-based stains have excellent UV stability and wear resistance, permitting you to use them on both interior and exterior concrete slabs. However, makers of some dyes do not recommend their products for exterior use because the color can fade when exposed to direct sunlight. If you are considering using a dye for an outdoor project, be sure to check its suitability for exterior applications. Most manufacturers also recommend applying a clear sealer to newly stained or dyed concrete for additional protection from abrasion, chemicals, and UV exposure.
