PROPERTIES Brushable elastomeric acrylic waterproofer for roofs with long-lasting durability. It creates a white protective membrane, without seams nor joints, with excellent adhesion to various substrates. Due to its high modulus of elasticity, it can absorb intense expansions and contractions, without the necessity for additional reinforcement (mesh). It protects surfaces from moisture that can adversely affect concrete rebars. Certified by the University of Athens (Department of Physics, Division of Applied Physics), as `Cool’ material of low thermal conductivity and high reflectivity. Classified as product for surface protection of concrete surfaces per EN 1504-2. Why should I choose the DS-220 to waterproof my roof? • Distinguished for its remarkable resistance to adverse weather conditions, maintaining its properties in temperatures ranging from -30°C to +90°C. • It is resistant to the corrosive gases of the atmosphere, such as carbon dioxide, sulfur oxides, chlorides, etc. • It contains new age UV filters, contributing to its long-lasting resistance against the destructive effects of solar radiation. • It provides walkable surfaces that do not stick. • It can effectively cover substrate cracks and it is not affected by the (possible) creation of new ones on the substrate itself. • It presents excellent resistance, even to standing water. • It reduces the temperature absorption of the roof slab up to 20%, due to its reflective action (80%), resulting from its exceptional whiteness. • It reduces the indoor temperature of spaces under the roof throughout the sumTECHNICAL SPECIFICATIONS: • Form-Color: Viscous paste-White • Density: 1.40±0.05kg/lt • Elongation at break (per ASTM D 412): After 8 days of curing and at 1mm thick membrane, the elongation at break was determined at 400% • Full tightness: 7 Αtm per DIN 1048 Acrylic elastomeric waterproofer (liquid rubber)
