5 litre Primer to suit Tanking Membrane

Description
A cold applied solvent based bituminous solution designed to penetrate seal porous surfaces prior to the application of covering materials. Conforms to BS code of practice 144, part 3.

Uses
Seals porous substrates and encourages the adhesion of bituminous waterproofing systems and sheet coverings. It may be applied successfully to a wide range of surfaces:

Metal - mild steel, zinc, lead
Concrete
Asbestos Cement
Slate
Lightweight Concrete Screeds

Methods of Use
Apply by brush or spray

Surfaces should be clean, ie free from all oil, grease, dirt, dust and loose debris. On metal surfaces all loose rust should be removed using wire bristled brush and where advanced signs of corrosion are evident these areas should initially be treated with a rust inhibitor such as red lead. Surfaces should preferably be dry although general purpose primer will adhere to damp but not wet surfaces. General purpose primer should be applied evenly across the surface in one generous coating. It is resistant to rainfall within 2-30 minutes of its application.
