Verified by manufacturer 1 year ago
Acrylic crack-bridging intermediate protective coating for concrete.
Application
- Crack-bridging intermediate coat beneath Sikagard®- 550 W Elastic top coat.
- Filling pores, cavities and blowholes.
- Levelling / re-profiling layer.
Suitable for:
- Protection against ingress (Principle 1, method 1.3 of EN 1504-9).
- Moisture control (Principle 2, method 2.3 of EN 1504-9).
- Increasing the resistivity (Principle 8, method 8.3 of EN 1504-9).
Description
Sikagard®-545 W Elastofill is a one-part, acrylic, water based, crack-bridging, intermediate surface protection coating for concrete.
It fills surface pores, cavities and blowholes or provides a smooth or textured levelling layer for subsequent protection coating topcoats. Sikagard-545W Elastofill is part of the Sikagard crack-bridging, anticarbonation, surface protection coating system for concrete and complies with the requirements of EN 1504-2.
Features and benefits:
- Water dilutable.
- Easy to apply compared to cementitious levelling
- coats.
- Smooth filling of pores, small cavities and blowholes.
- Good diffusion resistance against CO2 reducing the rate of carbonation.
- Good water vapour permeability.
- Crack-bridging at low temperatures (-20°C).
- Retains board mark texture/formwork patterns on finished surface.
- Resistant to freeze/thaw and de-icing salts.
- CE marked.
