Self-adhesive modified bitumen is typically applied using a torch or hot air method to ensure proper adhesion to the substrate. The surface must be clean and dry before application. The material is unrolled and pressed onto the surface, allowing the adhesive properties to activate upon contact. For optimal performance, it is essential to follow manufacturer guidelines regarding temperature and installation techniques, ensuring a seamless bond that enhances waterproofing and durability in asphalt or bitumen modification processes.
