Technical Information
Product Description

A quick drying solvent based low viscosity bitumen primer. it is used as a primer coat on masonry and concrete substrates to improve the adhesion of bitumen based membranes and coatings. Is low in viscosity, which allows it to penetrate into the concrete pores and improve the adhesion between the membrane and the concrete surface. In addition to that, the primer also acts as a binder for dust particles which gets accumulated on the concrete surface even after cleaning.

Advantages
  • Improves the adhesion between bitumen based sheet membranes and coatings
  • Cold applied, does not require heating
  • Binder for dust particles
  • Anti corrosive & Conforms to the following standards ASTM D 41 - Asphalt primer for roofing, damp proofing and waterproofing
