MEMBRAPOL 250 W/I is an elastic waterproofing membrane formulated with acrylic resins modified with elastomeric polyurethane resins in water dispersion, containing calibrated mineral fillers with a barrier effect, giving the product excellent impermeability, mechanical, chemical, thermal and UV UV.

MEMBRAPOL 250 W/I can be cold applied with a brush, roller or airless without mechanical fixings, it hardens directly on the substrate and forms a continuous waterproof coating, which efficiently protects old and new structures in the long term. Versatile product applicable on different types of support such as concrete, bituminous sheaths, metal, wood and fiber cement.

MEMBRAPOL 250 W/I is indicated as waterproofing for balconies and terraces exposed to both UV rays and to be tiled, for commercial and industrial roofing.
