App Membrane Primer

APP Primer is a high-quality bituminous primer specially formulated for preparing surfaces before the application of APP (Atactic Polypropylene) modified bitumen membranes. It enhances adhesion between the substrate and waterproofing membranes, ensuring a strong, durable, and leak-proof bond. The primer is easy to apply by brush, roller, or spray and penetrates deeply into porous surfaces such as concrete, masonry, and metal. It also helps seal dust and small pores, creating a smooth, uniform base for waterproofing works. Key features: Improves adhesion of APP membranes Quick-drying and easy to apply Suitable for concrete, brick, stone, and metal surfaces Enhances durability of waterproofing systems
