Köster Bitumen Primer
Description

Köster Bitumen Primer is a cold applied, low odour, solvent-containing bitumen primer. It contains a bonding agent admixture and displays excellent penetration properties. It acts as a dustbinder and as a bonding agent for subsequent hot or cold applied liquid bitumen coatings and self-adhesive membranes.

Suited for all absorbent mineral surfaces, metal sheets, wood and bitumen roofing felt. Suited as primer for bitumen thick film sealants and cold applied self-adhesive bitumen membranes, as well as overcoating old layers of bitumen (refurbishment of old thick film sealants and bitumen coatings).
