• Classified as C1 according to DIN EN 1062-1:2004-08.
• Freeze-thaw stability tested according to ASTM D2243.
• VOC content tested according to ASTM D3960:2005.
• VOC emissions after application comply with LEED Version 4 requirements.

Substrate Preparation

New concrete and cementitious surfaces must be allowed to cure for at least 28 days before applying the primer or coating system.

The substrate must be structurally sound, clean, dry and free from dust, oil, grease, salts, mold, laitance, weak areas, protrusions and other contaminants that may reduce adhesion.

Remove old paint completely from previously painted surfaces. Repair cracks, holes and surface defects using suitable repair and filling materials before application.

Application Conditions

• The application temperature must not be below 5°C.
• The substrate moisture content must not exceed 8%.
• The relative humidity in the working area must not exceed 70%.
• The substrate pH must not exceed 9.
• Do not apply to wet or damp surfaces.
• Do not apply a subsequent coat until the previous coat is fully dry.

Mixing and Dilution

Stir WHITE SAND ANTI-CARBONATION thoroughly before use. Clean tap water may be added according to the selected application method and site conditions.

• Airless spray: dilute with approximately 0-10% clean water by volume.
• Conventional air spray: dilute with approximately 15-25% clean water by volume.
• Roller or brush: dilute with approximately 10-15% clean water by volume.

Application

1. Apply one coat of a suitable WHITE SAND primer to the prepared substrate.
2. Allow the primer to dry completely.
3. Apply at least two uniform coats of WHITE SAND ANTI-CARBONATION.
4. Use airless spray, conventional spray, a soft roller or suitable brush.
5. Maintain the recommended wet and dry-film thickness.
6. Allow each coat to dry fully before applying the next coat.
7. Maintain a minimum recoating interval of approximately eight hours.

Yield and Coverage

The theoretical coverage is approximately 4-8 m² per litre at a dry-film thickness of approximately 50-100 microns per coat.

Actual consumption depends on substrate condition, surface porosity, application method, applied thickness, ambient conditions and material wastage.

Drying and Curing

• Surface dry: approximately 30 minutes.
• Hard dry: approximately 4 hours.
• Minimum recoating interval: approximately 8 hours.
• Full cure: approximately 7 days.

Cleaning

Clean all tools and application equipment with clean tap water immediately after use. Hardened material must be removed mechanically.

Storage and Shelf Life

WHITE SAND ANTI-CARBONATION has a shelf life of 24 months when stored in its tightly sealed original container at approximately 25°C in a dry, cool and well-ventilated location.

Packaging

• 16 litre drums.

Health and Safety

• Read the precautionary information on the container and the latest Safety Data Sheet before use.
• Wear suitable protective gloves, safety goggles and protective clothing.
• Avoid contact with the skin and eyes.
• Avoid inhaling paint mist or vapour.
• Apply in a well-ventilated area.
• Provide forced ventilation when working in enclosed or poorly ventilated areas.
• Keep out of the reach of children.
• Dispose of leftover material and empty containers according to applicable local regulations.

Quality and Technical Support

WHITE SAND products are developed and manufactured under a quality-oriented product-development process and an independently standardized quality management system.

WHITE SAND provides technical assistance regarding concrete assessment, substrate preparation, primer selection, film thickness and anti-carbonation coating applications.
