Form release agent is a cost-efficient alternative to traditional brick waxing, which can leave surfaces stained with wax residue and precast plants damaged from post-cleaning wax runoff. Brick Release reacts with lime present in concrete to create byproducts that prevent the adhesion of concrete to brick surfaces. The resulting crisp, clean release creates a finished surface devoid of concrete residue. Nox-Crete Products Group. Booth 411
