High-Performance Mixes

Some prepackaged mixes are formulated to produce countertops with exceptional performance features, such as high strengths of 5500 psi or greater, minimal cracking and shrinking, lighter weights, faster setting times, greater workability and the ability to be poured into thinner slabs. These qualities can enhance the durability of your countertops, help prevent damage during shipping and installation, and improve productivity.

The Stamp Store's enCounter mix blends white limestone rock, well-graded aggregates, cement, and performance-enhancing admixtures to minimize shrinkage and cracking, improve finishability, and achieve strengths topping 8000 psi after 28 days. Stamp Store owner Doug Bannister says enCounter is more flexible and structurally stronger than other countertop materials, which allows the material to take any shape and be cast in long unsupported spans, making it ideal for cantilevered countertops (see Bending the Rules in Concrete Countertop Mix Design). Packaged in 50 pound bags, the mix is available in white or gray and can be integrally colored with a choice of nine liquid pigments. For additional decorative effect, the surface can be polished after it cures to expose the white limestone rock.

Counter Weight from Decosup is touted as a lightweight countertop mix with both the structural strength and workability of regular concrete. It weighs up to 33% less than other standard concrete mixes, according to the company, reducing the load on the countertop base and allowing installers to haul around bigger pieces. Counter Weight achieves strengths of 5500 psi within 28 days and it sets quickly, permitting diamond polishing, staining or dying the day after placement. The mix is light in color and tintable, resulting in brighter color tones.

As the name implies, Xtreme Countertop from SureCrete achieves super-high compressive strengths exceeding 10,500 psi and flexural strengths greater than 1,400 psi. The cementitious composite material is suitable for both cast-in-place or precast projects and permits you to pour countertops as thin as ½ inch with no rebar and wire mesh. The mix is also fast setting and can be removed from the mold after 4 hours and polished with diamond abrasives after 8 hours. The product is packaged in 50-pound bags to which you add a gallon of liquid modifier and SureCrete's Color Pack for an integral tint, if desired.
