Application Method
Application was carried out in accordance with Belzona Know-How System Leaflet VPF-11. To provide an initial seal to the crack, the fast-setting Belzona 1211 was deployed, stopping the leak and eliminating the risk of explosion. This allowed the surface to be prepared, and the substrate was ground to achieve the optimum surface profile. Belzona 1111 was then applied in two layers incorporating Belzona 9341.
