Editor's note: In each issue, we will feature sponsors of the Concrete in Artistry demonstrations at World of Concrete 2010. This month, we look at Concrete Solutions. Watch the demonstration video atwww.concreteconstruction.net.
Resurfacing can be an attractive, cost-effective alternative to removing and replacing cracked or stained concrete. Representatives from San Diego-based Concrete Solutions Inc. demonstrated several resurfacing techniques using texture and color: spray texture, color flake, and stamping.
Each technique requires a bond coat and a texture coat. The bond coat must be dry for spray texture and color flake applications, but wet for stamping.
To create a spray texture, Concrete Solutions used polymer coating with added sand, cement, and silica. They used a hopper gun sprayer to coat the concrete surface with nickel- and dime-sized drops.
For a color flake finish, they first applied an epoxy primer and let it dry overnight. They added a urethane coat and broadcast the color flakes by hand.
The stamping finish was the most dramatic. The contractors spread concrete over a fresh bond coat, stressing the importance of leaving enough material at the edges for stamping. After adding a liquid release agent, they stamped the fresh concrete with rubber forms. Another colored release agent created a blended look on top.
