Bitumen Primer

Bitumen primer is applied to any surface that bitumen needs to adhere to. The primer provides a key, and seals any porous surfaces that the bitumen products need to adhere to and can be applied to most of surfaces including concrete, brick work, metal materials and existing bitumen surfaces.

By definition, a primer comes first and serves as a base for what should follow — whether it’s attending the primary grades at the beginning of school, priming an engine to start or using a primer coat applied prior to painting a wall. Similarly in commercial roofing, a primer is used as the first step in the application of a roof coating or membrane to aid in the proper bonding of the product to the surface.

Bitumen Primer is bitumen based primer for the surface conditioning of concrete and timber substrates prior to the application of heat fused APP and SBS modified bitumen membranes. Bituminous primers and black bituminous paints produced with oxidised bitumen and selected pure solvents. Black bituminous paints are used to anchor bituminous membranes, coat pipes, protect concrete and metal structures; they can also be applied on wet surfaces. Suitable for anchoring “hot” applied bituminous coatings on metal surfaces (oil and gas pipelines, aqueducts, etc.).

They are also suitable for sealing the porosity of concrete substrates as well as for preparing a valid binding primer for multiple bituminous waterproofing coats and bituminous membranes. The product has a fast curing time, excellent penetration and adhesion to the substrate and absence of superficial tackiness.

 

Features of Primer

  • Improves the bond of bituminous materials
  • Binder for dust particles
  • Surface dressing to masonry and metal surfaces
  • Water-resistant.
  • Corrosion and chemical resistant.
  • Penetrates and seals porous surfaces.
  • Fast-drying.
  • Cost-effective, no heating, thinning or mixing.
  • Compatible with various substrates and structures.

TYPES OF PRIMERS

Solvent Based Bitumen Primers

Geflow  is a premium quality, quick-drying solvent-based bitumen primer. It acts as a primer and sealer coat for masonry and concrete to improve the bonding of bituminous materials. When dry, the product forms an odourless and seamless free bitumen film suitable for the protection of metals, concrete roofing felt, fiber cement, corrugated iron, asphalt and wood against water attack.

PROPERTIES

  • Versatile bituminous primer for porous and non-porous surfaces.
  • Cold applies, does not require heating. Rapid drying. Seamless/ joint free.
  • Can be applied on vertical and horizontal surfaces.
  • Improves the adhesion between bitumen-based sheet membranes and coating.
  • Excellent coverage rate.
  • Strengthens surfaces, eliminating loose dust.
  • Excellent adherence to all traditional substrate.

Water Based Bitumen Primer

Geflow is an emulsified bitumen based primer designed for applications as a primer and sealer coat. Primer helps to block dust and reduces concrete porosity. The product provides good adhesion, penetration of the substrate and above all that it is formulated with water, therefore it is not flammable and is not dangerous to use. The product is odorless.

PROPERTIES

  • Thanks to its superior adhesion, the bituminous membrane can adhere on the surface excellently.
  • After evaporation of the water it contains, it forms a waterproof and water-insoluble layer.
  • Suitable for interior applications because of non-toxic and non-flammable content.
  • Water-based. Environment-friendly.
  • Adheres perfectly to all kinds of surfaces, even when the surface is moist
