KingCoat A®
One component water based acrylic elastomeric protective anti carbonation coating system.
Overview
KingCoat A is a high build elastomeric, microporous coating exhibiting excellent resistance to attack from carbon dioxide, airborne chlorides and acid rain, with exceptional weathering resistance. KingCoat A has excellent crack bridging properties, yet provides a smooth protective, decorative coating for concrete and other masonry surfaces. For effective anti- carbonation protection a two-coat treatment is recommended after the application of the silane siloxane based impregnating primer. The product is formulated to give a tough flexible and coloured coating which will give a waterproofing coating to a wide variety of substrates. A textured finish may be obtained if required.
Applications
- Bridge abutments
- External concrete surfaces of storage tank and masonry surfaces
- Multistory building and villas
- Where a high external tough coating is required
- Concrete cladding
Advantages
- High build elastomeric, microporous coating
- Excellent resistance to carbon dioxide, airborne, chlorides and water borne
- Exceptional weathering resistance
- Excellent crack bridging properties
- Protective and decorative coating
- Excellent waterproofing characteristics
- STANDARDS KingCoat A complies with the requirements of EN 1504-2 Surface Protection Systems Principles 1.3, 2.2 and 8.2
