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.
Applications
- Roofs and inverted roofs
- Balconies, channels, fountains, and water tanks
- Bridges and buried walls
- Planters and damp areas in bathrooms and kitchens (under tiles)
