Bitumen Primer Solution Low Viscosity High Penetration WaterProof 1 L

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.

Application Instructions:
         Care needs to be taken over preparation of surfaces before application. All surfaces must be free from oil, dirt, dust and loose debris. On metal surfaces all loose rust should be removed using a wire brush and where advanced signs of corrosion are evident the area be treated with a rust inhibitor.

         Surfaces should be dry for best results, although Bitumen Primer will adhere to damp but not wet surfaces. Bitumen Primer is resistant to rainfall within 20-30 minutes of application.

         Do not use in temperatures less than +5°C.
