Defy Split-Face Block Water Repellent

DEFY Split Face Block Water Repellent is a waterborne block sealer that causes water to shed, and significantly reduces water penetration into a wall system. It is specifically designed for lightweight, split face and fluted block. This product is a silane/siloxane blend with acrylic elastomers that penetrate small pores and reduces the size of larger ones. This combination gives DEFY Split Face Block Water Repellent the advantages of both a film forming coating and a hydrophobic silane/siloxane water repellent.

This UV stable product allows for penetration of up to 3/4 of an inch or more depending on porosity of the concrete masonry unit. This creates a deep, long-lasting waterproof zone within the surface while producing only a minimal glossy look.

Coverage Rate:
40 - 125 sq. ft. per gallon, depending on surface porosity
