High-Performance Solvent-Based App Primer

APP Primer is a high-performance, solvent-based bituminous primer formulated with oxidized asphalt and fast-evaporating solvents for rapid drying and superior penetration. Designed to enhance adhesion between concrete, metal, or masonry substrates and APP-modified bitumen membranes, it creates a tacky, dust-free surface that ensures optimal bonding. Ideal for both torch-on and cold-adhesive applications, APP Primer is resistant to water, alkalis, and mild acids. It comes ready-to-use, with a coverage rate of 4–6 m2/L, and dries within 30–60 minutes, depending on ambient conditions.
