CHRYSO DP BONDING AGENT is a two component solvent free thixotropic epoxy resin bonding system for joining old concrete to new concrete and old concrete to old concrete
Application
Apply a thin layer of DP BONDING AGENT with brush or squeeze
to the existing surface, working well into the substrate. Place
fresh concrete/mortar while it is still tacky (2-5 hours). A second coat of CHRYSO DP BONDING AGENT may be applied after the first thin layer of the applied DP BONDING AGENT passes its tacky stage, prior to placing the freshly mixed concrete or mortar. Good concrete practice should be followed in placing, consolidation and curing of concrete. While application, the substrate temperature should be at least 5°C but not above 40°C.
