Protective Coating for Concrete and Masonry Sikagard-675 W GB ElastoColor is a one-part, plasto-elastic water dispersed coating based on styrene acrylate dispersion for the protection and enhancement of fair-faced concrete and masonry. Sikagard-675 W GB ElastoColor can be applied over existing coatings or directly onto concrete and masonry surfaces. Sikagard-675 W GB ElastoColor complies with the requirements of EN 1504-2 as a protective coating. - Suitable for multiple substrates (i.e. concrete, masonry, fibre cement, sound coatings, etc.).
- 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 CO 2 (carbon dioxide).
- Reaction to fire classification B-s1,d0 (as a standalone coating).
- Reaction to fire classification A2-s1,d0 achievable when used as a Sika System.
