Uses
The Bitumen Primer by Cromar is an excellent product that improves the adhesion of bitumen products onto a surface.

Preparation
Preparing the surface is vital to achieving optimal adhesion. Start by checking the surface, ensuring it's sound, stable and free from contaminants, including dirt, dust, grease, oil and organic growth. The best way to remove these is using a stiff brush; with the organic growth, using a fungicide is vital as it eradicates the spores, preventing them from returning. Any signs of rust need to be treated with a rust inhibitor.
