Technical review pending. This reference record is awaiting verification against current manufacturer documentation. Confirm numerical values, product suitability and installation requirements before specification or use.
Overview
MC1 asphalt primer is a medium-curing liquid asphalt-based material used as a primer or bonding agent before applying asphalt layers or waterproofing membranes. It penetrates concrete and masonry surfaces, enhancing adhesion for subsequent layers of asphalt or bitumen-based systems.
Main Uses
- Surface primer before applying asphalt layers
- Bonding agent for waterproofing membranes
- Used in road works before tack coat application
- Enhances adhesion of bituminous layers on concrete
- Suitable for bridges, parking lots, and building foundations
