Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet TCC-1. Angle iron was bonded with Belzona® 1211 to the tank to support fabricated steel bands during application. Belzona® 1121 was used in conjunction with self tapping screws to bond the band to the tank wall. The interior of the tank was coated with Belzona® 5811 and the exterior painted.

 
 

Belzona Facts:

Alternative options included either replacing the entire tank or at least the top third. The Belzona option including coating the interior with Belzona® 5811 was 1/3 the cost of a new top and 1/10 the cost of a new tank.
