Sikagard 570 1-Component Water Based Waterproof Anti-Carbonation Highly Elastomeric Low Dust Pick Up Coating Deep Base 5 Gallon

Sikagard 570 1-Component, Water Based, Waterproof, Anti-Carbonation, Highly Elastomeric, Low Dust Pick Up Coating, Deep Base, 5 Gallon

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 that 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.

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.

Advantages:

• UV curable top coat for a more durable wearing surface and lesser dirt pickup.
• Can bridge dynamically moving cracks
• Excellent carbonation barrier
• Vapor permeable
• Provides resistance to weathering and frost
• Crack bridging properties maintained at low temperatures
• Can be fully reinforced with Sika Flexitape or Sika Reemat Standard
• Excellent long term UV light resistance
• Can be applied by brush, roller, or airless spray
• Good color stability
• Extremely resistant to dirt pick up and mildew
• Nontoxic, nonflammable as a system
• Easily maintained silk finish
