HEY’DI K-11 Gray is a brush or spray applied portland cement based system for waterproofing concrete and masonry through the crystallization process. HEY’DI K-11 waterproofs the positive side or the negative side of the substrate. Following proper application active water pressures force the crystal forming chemicals deeper into the substrate capillaries and pores to form a monolithic bond and become an integral part of the structure. Use with HEY’DI SB bonding agent in 1’s and 5’s.
