Butterfield Color has released its Pro Pack Countertop Admixture, the latest addition to its line of decorative concrete countertop mixes. The pre-measured admixture combines with most standard concrete bag mixes and water to create a high-performance concrete countertop mix. The Pro Pack Countertop admixture reportedly increases strength, reduces shrinkage, improves finishing characteristics, accelerates set time and allows decreased water-cement ratio. The mix may be colored with Butterfield Color Uni-Mix Color Packs (two color packs per unit are required), which are available in 24 standard colors. Mixes containing Pro Pack Countertop Admixture may be stained with Perma-Cast Sierra Stain or Elements Transparent Concrete Stain.
