Belzona Facts

The existing paint was insufficient to protect the joint areas as it didn't have the edge retention to get good coverage of the complex geometry in this area. Due to the movement in the substrate, traditional protection systems were not suitable as these may crack in service. An added benefit for the customer is the ability to inspect the bolts at a later date easily.
