AC 137

Water Repellent for Concrete / Cement Surfaces and Cracks

AC137 is a water repellant effective when applied on minineral oxide surfaces, such as, silica, cement, concrete, granite and most natural stones, etc  It is not a coating.  It is colorless and is not film forming.  It repels water by lowering the surface tension of the treated surface or cracks.  It can prevents water infitration through cracks on walls or floors.
