HEY’DI K-11 becomes an integral part of the wall and waterproofs the negative or positive side through a crystallization process. HEY’DI SB is the bonding agent used with HEY’DI K-11. It improves adhesion, flexibility and the permeability resistance of the system. HEY’DI K-11 must be allowed to cure before applying a finishing floor system.
