Bitumen Primer may be applied by brush or roller. The applied film must be allowed to dry before being over laid with any waterproofing treatment so as to avoid solvent entrapment. The primer coat is a key to good surface preparation for all waterproofing products as it makes the surface compatible with the waterproofing layer being applied above it. Our bitumen primer is the most affordable and high-quality products that give good coverage and provide strong adhesion to surface for APP membranes as well as liquid membranes. Primer is a low viscosity bituminous solution. It is highly penetrative and has good adhesion to most surfaces.
Primer consists of the bituminous black paint range used especially in industrial environments, they can be applied on both clean and dry, as well as damp surfaces, especially those in metal.
Instructions for Application
Th primer should be thoroughly stirred before use. The surface should be dry, clean and free of loose materials, dirt, soil, grease, oil or other impurities. Apply Bitumen Primer by means of a brush, roller or spray gun @ of 5-6 m²/lit into the entire coverage area of the substrate and allow drying. The drying time and coverage depend on the porosity of the substrate and the environmental conditions.
How To Use
- Thoroughly clean surface to be treated.
- Surface to be treated must be completely free of water.
- On bare metal, a rust-inhibiting product, such as a red oxide or zinc phosphate, should be applied and allowed to harden prior to application.
- Bitumen primer is supplied ready for use.
- Apply a thin coat by brush, roller spray and avoid pooling.
- The primer should extend at least 75mm beyond the area to be waterproofed.
- Leave to dry for 3-6 hours.
Most Suited For:
- Concrete roofs and floors.
- Cementitious screeds/ renders.
- Bitumen felt.
- Mastic asphalt.
- Weathered corrugated iron and steel.
- Priming of metal, timber, clay or cement bricks, and other porous and non-porous surfaces
