Verified by manufacturer 1 day ago
Anti-carbonation protective coating system for concrete consisting of Sikagard® 552 W Aquaprimer and Sikagard®-675 W GB ElastoColor.
Application
Concrete protection system. Can be applied over existing coatings or directly onto the concrete surfaces.
Description
Anti-carbonation protective coating system for concrete consisting of Sikagard® 552 W Aquaprimer and Sikagard®-675 W GB ElastoColor.
Sikagard®-552 W Aquaprimer:
A one-part waterborne adhesion promoting primer for water dispersed polymer paint coatings.
Features and benefits:
- Waterborne - safer to use than solvented products.
- Water vapour permeable.
- Good adhesion to concrete.
- Single component - ready to use.
- Easy to apply.
- Compatible with Sika® Anti-Carbonation Coatings.
Sikagard®-675 W GB ElastoColor:
A one-part, plastoelastic water-dispersed coating based on styrene acrylate dispersion for the protection and enhancement of fair-faced concrete. Sikagard®-675 W GB ElastoColor can be applied over existing coatings or directly onto the concrete surfaces.
Features and benefits:
- Water vapour permeable.
- Resistant to weathering and ageing.
- Application by roller brush or spray.
- High covering power (good opacity).
- Prevents water ingress.
- High diffusion resistance to carbon dioxide (CO₂).
Complies with the requirements of EN 1504-2 as a protective coating. CE marked.
