Control Finish is a powered concrete finishing aid, packaged in our signature water-soluble bags. It is easily mixed into a solution that can cover up to 1,000 square feet of freshly placed concrete. Unlike other finishing admixtures, Control Finish is formulated to be worked into the surface of the concrete. So you don’t have to wait around for it to evaporate. It contains no hazardous materials and won’t delay the actual setting time of the concrete.
