A water based, multi-purpose, liquid copolymer specifically designed to improve the performance of cement patches and repairs. Mix directly into the repair material to increase adhesion, bond strength, tensile and flexural strength, and water and chemical resistance. Or apply as a bonding agent to substrate to increase adhesive strength of repairs, patches and coatings. For vertical, horizontal or overhead applications, interior or exterior use, above or below grade surfaces. Exceeds ASTM C-1059 Type I and II and ASTM C-932 requirements.
