How to use

Surface Preparation

The surface shall be cleaned thoroughly of all contaminants
like dust, traces of curing compound, oil, grease. Light
mechanical grinding/grit blasting/high pressure water jet
may be used to clean the surface of all the contaminants
depending on the degree of contamination on the surface
to be coated


It is highly recommended to apply a priming coat prior
to the application of the Polycoat RBE 5 coating on the
substrate. The primer can be prepared in the site by diluting
Polycoat RBE 5 with 20% water. Apply the rubberized bitumen coating
@1–4m²/L/coat. On vertical areas, it is recommended
to apply the coating in multiple layers 


Care shall be taken to ensure that the first coat is not punctured during the application of the second coat. However, if the coating is damaged, the area can be readily over coated provided the surface preparation is done properly
