Application Guidelines
- Surface Preparation: Ensure the surface is clean, dry, and free from contaminants such as lichen, moss, grease, oil, and dirt. High-pressure water cleaning (greater than 2000 psi) is strongly advised. Do not use acid or caustic cleaning products.
- Priming: Apply Nutech Hypo cleaner at least 2 hours before pressure washing to kill all moss, mould, lichen, and fungus.
- Application: Apply two coats of Terraglaze using a brush, roller, or spray equipment. Allow sufficient drying time between coats.
- Curing: Full curing is achieved after 7 days under normal conditions.
Note: Before application, test the surface with water droplets to ensure penetration. If water beads on the surface and is not absorbed, the surface is likely vitrified, and Terraglaze is not recommended.
