Direct Bond lining systems are suitable for most level, masonry substrates. The substrate must be clean and dust free with all loose material removed. Substrates with a high suction rate should be treated prior to bonding with a PVAC agent.

Walls with higher risk of moisture ingress, such as solid masonry external walls, can only be bonded to once appropriately treated. Refer to our drywall manual for full details of the direct bond system.
