Directions for use

The surface must be clean, dry, and free of contaminants that affect adhesion (max. humidity 5%). Fresh concrete structures must dry for at least 28 days. Mechanically remove old membranes, dirt, grease, oils, and dust. Do not clean with water. Do not apply on surfaces treated with siloxane, silane, silicone, or water repellents. Joint and crack treatment: clean, locally prime, and let dry for 2-3 hours. Fill joints and cracks with Juntanet and let dry. Prime non-absorbent surfaces (ceramics) with TILE-PRIMER. Pour the membrane onto the surface and spread with a roller or notched trowel. After 12-18 hours, apply a second coat. A third coat provides better results. Do not apply with a thickness greater than 1 mm per layer. Application temperature 5 °C to 35 °C.

Sealpul 250

Waterproof polyurethane membrane

Elastic liquid-applied polyurethane membrane. Once applied, it creates a membrane that seals, protects, and waterproofs surfaces, providing long-lasting waterproofing as it cannot be dissolved in water. It has very high elasticity and is not affected by sunlight. It is used to achieve a perfect seal in contact with water and can be walked on after 24 hours.
