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.

Usage

Protection and enhancement of concrete and masonry structures.
Concrete repair works on Sika levelling mortar, fibre cement and overcoating existing soundly adhering coatings.
Suitable for protection against ingress (Principle 1, method 1.3 of EN 1504-9).
Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9).
Suitable for increasing the resistivity (Principle 8, method 8.3 of EN 1504-9).
