Sikagard 570 is an exceptionally elastomeric, high build, waterborne coating designed to accommodate movement and cracking in structures. The coating is cured by exposure to the UV radiation present in sunlight, developing a surface skin which is relatively harder than the bulk of the coating beneath. Thus, it has a hard wearing surface but the underlying coating is comparatively mobile, tolerating pronounced movement without cracking or splitting. Similarly, as more material is gradually exposed due to natural erosion, the hard surface is maintained. The coating dries rapidly to a matte finish, and retains its elasticity both at very low temperatures and in extremes of heat, protecting substrates against weathering, water ingress and aggressive atmospheric chemicals. In addition it also provides an effective barrier to carbonation when applied over reinforced concrete. Sikagard 570 exhibits excellent color retention, has a dirt resistant surface, is capable of very high moisture vapor transmission and has excellent low temperature crack bridging properties.
Sikagard® 550 W Elastocolor
Elastomeric, crack-bridging, anti-carbonation, acrylic protective coating. Sikagard 550W Elastocolor provides protection to reinforced concrete from the ingress of carbon dioxide and other aggressive gasses. It offers high resistance to chlorides and other waterborne salts and excellent UV light resistance. Sikagard 550W Elastocolor will not act as vapor barrier and will enhance the aesthetic appearance of the structure.
UseProtective, crack-bridging coating for concrete, mortar, stucco, masonry, and exterior finishing systems subject to cracking/dynamic movement. On building and civil engineering structures subject to cracking. As the top coat in complete repair and protection systems.
