Products:

Substrate:

Carbon Steel

 
 

Application Method:

The crane roof was grit blasted to SP 10 with a minimum anchor profile of 3 mils. The repair area was cleaned and degreased with Belzona 9111. All through/thin wall defects were repaired with the Belzona Plate Bonding System using Belzona 1121 to adhere plates. Belzona 3921 was installed by brush and allowed to cure. A two layer system of Belzona 3111 was installed, incorporating Belzona 9311 in the first layer.

 
 

Belzona Facts:

Due to the severe deterioration of the roof, the crane operators were no longer protected from the weather when operating. Replacement of the crane cab was very expensive plus a great deal of downtime. Restoration of the crane roof using the Belzona system was less than US $3,000 for materials and labor with no downtime.
