Preparation
Preparation is essential; if not completed correctly, it can cause further problems in the future. Ensure the surface on which you intend to apply this is stable, clean, dry, and free from contaminants such as dirt, grease, oil, etc. Also, note that this product creates stress during movement, so ensure it's applied appropriately. You can enhance the adhesion of this product using the appropriate primer/propriety to clean the surface before application.
Application
- Cut the tape to the required length and release the film.
- Place it into place, pressing firmly, using a hard-wheeled roller or another suitable tool to ensure no air is trapped.
- You can enhance adhesion further by heating it whilst it's on the surface.
- Any overlaps must be at least ≥ 50 mm.
