It is a waterproofing elastomeric resin coating, based on modified acrylic resins. Resistant to even aggressive atmospheres, waterproof but permeable to water vapour. Specifically used for water-proofing mortar coverings with crack bridging capacity, on the surface of concrete load-bearing structures subjected to bending and compression, already cracked or at risk of cracking. It can be used for protection, anti-carbonization, and weather proofing concrete, both during pouring and prefabrication of bridges, viaducts, and similar roadworks structures Suitable for the protection of solar slabs, terraces, flat roofs under paving and, specifically, over Manti Ceramic nanotechnological insulation. It is also suitable for coating concrete structures such as piezometric towers, evaporation towers, the outside of purification tanks, even in aggressive industrial atmospheres. Featuring excellent direct adhesion on clean and dry cementitious substrates.
