How to Apply WP7-301 Roofing Waterproof

For a successful and lasting repair, please follow these steps:

1. Surface Preparation: Ensure the surface is clean, stable, and free from ice or snow. If necessary, clean the area, remove any loose material and hardened bitumen, and dry the surface without direct heating. For blisters, cut them open in a cross shape to release trapped air or moisture.
2. Reinforcement: For major repairs or large cracks, reinforce the area by embedding a piece of roofing felt or fiberglass tape into the first layer of paste.
3. Application: Apply the product directly from the cartridge with a caulking gun, or use a brush or spatula for larger areas from a pot. Aim for an even layer thickness of 2mm. If you are finishing with a slate stroke for UV protection, a 1mm thickness is sufficient.
4. Finishing & Cleanup: Smooth the paste as needed. Clean tools and any excess product immediately with Tec7 Cleaner.
