Concrete

 
 

Application Method:

Power wash and remove any loose concrete, remove the previous epoxy from the sump containment well. Concrete was pH tested prior to application of material. Followed the IFU for Belzona 5811 as to cure and overcoat time. Belzona 5811 was applied in two coats with a roller and brush system.

 
 

Belzona Facts:

Adhesion and protection from sodium hypochlorate was the princial reason Belzona 5811 was selected. The customer had a previous coating on the sump well floor and sides that delaminated and failed due to poor adhesion.
