Modified bitumen roof 77568 is applied through a multi-step process that involves heating and blending. Initially, the base bitumen is heated to a specific temperature to enhance its flow properties. Then, modifiers such as SBS (styrene-butadiene-styrene) or APP (atactic polypropylene) are added to improve elasticity and durability. The modified bitumen is then applied using torching, hot mopping, or self-adhesive methods, ensuring a strong bond to the substrate and optimal waterproofing performance.
