The MARSHALLTOWN Flat Out Countertop Mix was designed for quick production and pre-casting of countertops, concrete panels, and other architectural precast shapes and pieces. The dry mix is packaged in 55-pound bags and liquid polymer is packaged in 5-gallon pails. One pail of polymer yields enough material for approximately 6 bags of countertop mix. One bag of countertop mix requires 3.25 quarts of polymer to yield 0.42 cubic feet or approximately 5 square feet at 1" thick. The mix can be de-molded in as little as 3 hours and polished within 8 hours of pouring. Color this product by adding Uni-Mix® color packs, sold separately. This product is Made in the USA with Global Materials.
