Sikagard-680 S Betoncolor RAL7032, 30Kg

Minimum dry film thickness (DFT) to achieve full durability characteristics (CO 2 diffusion, adhesion after thermal cycling, etc.) = 101 μm. Maximum DFT to comply with H 2 O equivalent air thickness of 5 m (16.4 ft) = 290 μm.

+5 °C (+41 °F) minimum / +35 °C (+95 °F) maximum

< 85 %

Substrate and ambient temperature must be at least 3 °C (37 °F) above dew point.

+5 °C (+41 °F) minimum / +35 °C (+95 °F) maximum

Waiting time between coats:

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.

Full cure: ~5 days (+20 °C (+68 °F)).

Dust dry: ~30 minutes (+20 °C (+68 °F)).

Times are approximate and will be affected by film, thickness and changing ambient conditions particularly temperature and relative humidity.

These figures are theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

Preparation equipment

• Steam cleaning equipment
• Abrasive blast cleaning equipment
• High-pressure water jetting equipment

Application equipment

• Brush
• Short pile fleece roller
• Airless spray pressure: 150 bar, nozzle diameter: 0,38 to 0,66 mm (0.026 in), angle: 50° to 80°

Strictly follow installation procedures as defined in method statements, application manuals and working instructions, which must always be adjusted to the actual site conditions.

Note: Confirm waiting / overcoating times of any previous coats is achieved before applying subsequent coats (refer to waiting / overcoating time in Application Information).

Note: Confirm Product application conditions: substrate moisture content, substrate, air and product temperatures, relative humidity and dew point (refer to Application information).

Primer coat (if required)

1. Apply the primer evenly over the surface at the required consumption. Refer to the appropriate Product Data Sheet.
2. Protect primer from rain before applying protective coating.

Protective coating

Note: The product is supplied ready for use.

Manual application
