Sika Sikagard 570

Sikagard 570 is an elastomeric, UV curing, crack-bridging, anti-carbonation, fully reinforceable, acrylic protective coating. Sikagard 570 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 570 will not act as a vapor barrier and will enhance the appearance of the structure.

Sikagard 570 is cured by exposure to UV radiation present in sunlight, which aids in the development of a surface skin which is relatively harder than the bulk of the coating beneath. This leads to a more durable surface and reduced dirt pickup. Similarly, as the coating does eventually begin to wear, the exposed material will maintain its hardened surface.

Where to Use
Protective, crack-bridging coating for concrete, mortar, stucco, masonry, and exterior finishing systems subject to cracking/dynamic movement. For use on building and civil engineering structures subject to cracking or as the top coat in complete repair and protection systems.
