Belzona 1311 (Ceramic R-Metal)

Belzona 1321 (Ceramic S-Metal)



Steel and concrete


Application Method:

Sponge-Jet abrasive grit blasting was used to prepare the metal surface. Application was carried out in accordance with Belzona Know-How System Leaflet SHM-8. 


Belzona Facts:

Belzona provided the client with the solution to eliminate the outside environment to being able to affect the steel substrate. Due to time and the elements the pipe elbow was deteriorating. After preparation of the corroded metal surface using Sponge-Jet abrasive grit blasting, Belzona 1311 was applied and Belzona 1321 was then applied in two coats. This created a barrier and a smooth surface, and saved the client costs of having to retrofit a new pipe elbow, foundation alteration of a historic building, environmental challenges, and labor.
