Special Effects With Concrete Stains, Coloring Concrete

ADVERTISEMENTS

Decorative concrete artists have become quite creative in using acid stains, water-based stains, dyes and paints on concrete. Acid stains offer the most earth-like, weathered and warm colors. However, because of their iron oxide base, acid stains are available only in a limited color palette — earth tones. For a virtually unlimited palette, there are water-based acrylic stains. Dyes, too, come in more or less any color, with the exception of white.

Depending on whom you talk to, however, there can be some challenges with acrylic stains and dyes. While water-based stains eliminate the problem of neutralizing acid stain residue, some contractors express concerns about acrylics peeling in some conditions. Others are concerned about the colors of dyes fading with UV exposure, even though some dye products are said to be UV-resistant. Acid stains, for their part, are known for their color permanence.

Experienced contractors wisely spend time talking to the manufacturers of different colorant products about where and how they should be applied. Even in the same product category, there are differences in products across manufacturers. And while some decorative concrete artists may prefer to use only acid stains, others mix and match products with great results.

The real fun with stains and dyes is in the creation of special effects. Just look at some of the effects shown in the photos accompanying this article.
