How to Apply

1. Prepare the surface: Ensure the substrate is clean, dry, and free from dust, grease, and loose material. For porous surfaces, a bitumen primer may improve adhesion.
2. Cut to length: Measure and cut the required length of flash band using scissors or a utility knife.
3. Peel the backing: Remove the release liner from the adhesive side.
4. Apply firmly: Press the tape onto the surface, working from one end and smoothing out air bubbles as you go.
5. Seal the edges: Use a roller or the back of a spoon to firmly press down the edges for a complete watertight seal.

For best results on cold or dusty surfaces, clean with a damp cloth and allow to dry fully before application.
