Editor's note: Each issue, this space will be devoted to sponsors of the Concrete in Artistry demonstrations at World of Concrete. These sponsors had an opportunity to exhibit their products in live Contractor Clinic demonstrations throughout the week. This month, we look at The Stamp Store concrete countertop mix. VisitConcrete Construction TV to view the demonstration video.
Concrete countertops continue to gain acceptance by builders, architects, and homeowners as an up-scale design alternative to granite, topaz, and other high-end materials. The Stamp Store's enCounter Professional Countertop System is a special blend of rock, medium- and fine-graded sands, cement, and proprietary ingredients. Use it in either cast-in-place or precast applications.
The Stamp Store's Tim Frazier made a form at World of Concrete and filled it with the enCounter mix during demonstration at his booth. “ It's a very strong mix. Normally, it's a 9000 psi mix,” he said. “Water reducer reduces 20% of the water to 14,000 psi.”
A 50-pound bag covers about 3 square feet at 1.5 inches thick and 2.3 square feet at 2 inches thick. “Notice how liquefied the mix is,” says Frazier. “It is somewhat of a self-consolidating mix.” The fiber in the mix serves as reinforcement.
To polish the surface, allow the concrete to cure at least four days at normal temperatures. Consider using a liquid densifier and start polishing with a diamond cup wheel to start leveling or breaking the surface. If using dry pads, start with 100-grit and continue on to 200-, 400-, 800-, and 1500-grit pads. For more, visit www.thestampstore.com.
Women and Concrete Acid Staining
“Some people might cringe at the idea of living with concrete floors,” says Aylisa Marion. “But actually, concrete floors are surprisingly comfortable underfoot. And even better when you've done it yourself.”
Marion knows a thing or two about concrete. She and her husband Mark own Concrete Perceptions in Ardmore, Okla., and they participated in Artistry in Concrete at World of Concrete in 2009. Marion will instruct an all-day “women's only” Acid Stain class at The Stamp Store in Oklahoma City on April 17. “Women can acid stain a floor with no problem. You just need a little practice, and the right tools and products.” Telephone 888-848-0059, or visit www.thestampstore.com for more information.
