Protective Coating for Concrete and Masonry Sikagard-680 S Betoncolor is a one-part, solvent-based, decorative methacrylic protective coating for concrete and cementitious surfaces. It protects against aggressive atmospheric influences and promotes a self-cleaning effect on the treated surfaces. It is available as a clear coating. Sikagard-680 S Betoncolor complies with the requirements of EN 1504-2 as a protective coating. - Good resistance against weathering and ageing.
- Quick drying.
- Good opacity (coloured version).
- Applied by brush, roller or airless spray.
- Clear coating to maintain decorative exposed aggregate features.
- Rain resistant within a short time.
- Maintains the texture characteristics of the surface.
- High diffusion resistance against CO 2 reducing the rate of carbonation.
- Water vapour permeable.
- Reduced tendency to dirt pick-up and contamination.
- Suitable for sealing of green concrete in civil engineering works.

Packaging | Clear coating | 20 kg container |
Colour Thixotropic liquid | Clear coating | Final appearance: Smooth gloss finish |
- When the product is exposed to prolonged direct sunlight, splashed water containing de-icing salts or sea water, there may be some discolouration, a change in surface finish and colour variation. This has no influence on the function and performance of the product finish.

Application Information Layer Thickness Minimum dry film thickness (DFT) to achieve full durability characteristics (CO2 diffusion, adhesion after thermal cycling, etc.) = 101 μm.
Maximum DFT to comply with H2O equivalent air thickness of 5 m = 290 μm. Ambient Air Temperature +5 °C minimum / +35 °C maximum Relative Air Humidity < 85 % Dew Point Substrate and ambient temperature must be at least 3 °C above dew point. Substrate Temperature +5 °C minimum / +35 °C maximum Waiting Time / Overcoating Waiting time between coats: | Temperature | Time | | +10 °C | ~8 hours | | +20 °C | ~5 hours | | +30 °C | ~3 hours |
Note: Refresher coats of Sikagard-680 S Betoncolor can be applied without priming if the existing coating is fully bonded and is thoroughly cleaned. Times are approximate and will be affected by film, thickness and changing ambient conditions particularly temperature and relative humidity. Applied Product Ready for Use Full cure: ~5 days (+20 °C). Dust dry: ~30 minutes (+20 °C). Times are approximate and will be affected by film, thickness and changing ambient conditions particularly temperature and relative humidity. |
