Waterproofing

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.
