Description & Uses
Bitumen Primer is a low viscosity, high penetration, cold applied bituminous solution designed to prime and seal porous roof surfaces prior to the application of bituminous materials. It seals porous substrates and promotes the adhesion of bituminous waterproofing systems and sheet coverings.
May be applied to a range of surfaces:
• Concrete
• Asbestos cement
• Metals – mild steel, zinc & lead
• Slate, lightweight concrete screeds
Coverage Rates
The coverage per litre is dependent upon the porosity of the surface:
• Metal surfaces: 6-12m2 per litre
• Concrete: 6-8m2 per litre
• Lightweight concrete screeds and asbestos cement:
3.5-5m2 per litre.
Method of Application
Bitumen Primer should be applied by brush ensuring an even coat with no pooling, or applied evenly by airless spray.
