A premium co-polymer bonding compound designed for adhesion, improving flexibility, durability, and waterproofing. KA-Bond SBR can be added to mortar, screeds, or renders to provide these enhanced properties. It also serves as a strong adhesive primer for surfaces before applying tanking slurry for damp proofing. Mix the required amount of SBR with water at a ratio of 2:1, apply to the areas, allow to become 'tacky', and then apply your tanking for complete protection and added adhesion.
