Fast and safe to apply

- Pre-treat absorbent and porous surfaces with a primer for mineral and bitumen substrates (art. no. 5991540920)
- Cut to size, peel the protective film from the liner and apply ensuring there are no creases
- To ensure proper adhesion, press the tape onto the surface and smooth with a roller or similar tool
- When the strips are connected, the overlap must be at least 100 mm
- Keep in mind that the watertight membrane has limited resistance to UV rays and its external exposure duration is limited to 8 weeks
