WHITE SAND WR 50 is a low-viscosity, water-based, silane-siloxane penetrating hydrophobic surface treatment for concrete and masonry. It penetrates porous surfaces and reacts chemically to form a water-repellent barrier within the pores while allowing the substrate to breathe.
WHITE SAND WR 50 is used to provide long-lasting water repellency and surface protection for:
- Concrete
- Masonry
- Brickwork
- Natural stone
- Artificial stone
- Cement fiberboards
- Mortar joints
- Mineral paints
- Precast concrete
- Stucco
- Decorative concrete
WHITE SAND WR 50 penetrates deep into porous construction materials and reacts within the pores to create a hydrophobic lining. This prevents water penetration while allowing water vapor to escape, helping maintain the substrate's natural breathability.
WHITE SAND WR 50 is suitable for:
- Concrete structures
- Brick walls
- Concrete blocks
- Natural stone
- Artificial stone
- Cement fiberboards
- Mortar joints
- Mineral-based painted surfaces
- Decorative concrete
- Precast concrete elements
Key benefits include:
- Excellent water-repellent performance
- Deep penetrating protection
- Prevents water ingress
- Reduces chloride and sulphate penetration
- Maintains vapor permeability
- Allows concrete and masonry to breathe
- Protects against discoloration
- Helps reduce pollution staining
- Ready-to-use formulation
- No change to surface appearance or texture
Yes. WHITE SAND WR 50 provides effective water repellency by preventing rainwater and moisture from penetrating porous concrete and masonry surfaces while preserving their natural appearance.
Yes. By reducing the ingress of water-borne chlorides and sulphates, WHITE SAND WR 50 helps protect concrete structures from moisture-related deterioration and corrosion risks.
No. WHITE SAND WR 50 is formulated to penetrate the substrate without changing its texture or appearance, making it ideal for architectural concrete and decorative masonry.
Yes. WHITE SAND WR 50 is suitable for both vertical and horizontal concrete and masonry surfaces.
Yes. WHITE SAND WR 50 is supplied as a single-component, ready-to-use product that requires no dilution or mixing before application. Simply shake or stir the container before use.
The typical coverage is 3–6 m² per liter per coat, depending on the porosity of the substrate. A test area is recommended to determine actual material consumption.
Before application, the surface should be:
- Structurally sound
- Clean and dry
- Free from dust
- Free from dirt
- Free from paint
- Free from laitance
- Free from efflorescence
- Free from contaminants that may prevent penetration
Any cracks or joints should be repaired before application.
Yes. A dry substrate is essential to ensure proper penetration and optimum performance of WHITE SAND WR 50.
The preferred application method is using a low-pressure airless spray. For smaller areas, a brush or roller may also be used. On vertical surfaces, application should begin at the bottom and continue upward to ensure even coverage.
- Dense surfaces generally require one saturated coat.
- Porous surfaces may require two or more wet-on-wet saturation coats for optimum protection.
Yes. Applying a test patch is recommended to verify the surface appearance, penetration, and actual coverage rate before treating the entire surface.
Yes, but only after the acid has been completely neutralized. Failure to neutralize acid residues may affect product performance.
WHITE SAND WR 50 has a specific gravity of approximately 1.3 kg/L at 23°C.
WHITE SAND WR 50 is supplied in 20-liter barrels.
The product has a shelf life of 12 months when stored in its original unopened packaging in a dry, shaded location below 35°C.
Yes. Wear suitable protective gloves and safety goggles during handling and application. Avoid prolonged contact with skin and eyes. If contact occurs, wash immediately with clean water and seek medical attention if irritation persists.
No. WHITE SAND WR 50 is non-flammable and is not classified as a hazardous material under current regulations.
Yes. By minimizing water penetration while allowing water vapor to escape, WHITE SAND WR 50 helps reduce moisture-related deterioration, staining, and the ingress of harmful salts, extending the service life of concrete and masonry surfaces.
WHITE SAND WR 50 offers deep penetrating hydrophobic protection without forming a surface film. It maintains the natural appearance of concrete and masonry, allows substrates to breathe, reduces water, chloride, and sulphate ingress, and provides long-lasting protection against weathering, discoloration, and pollution, making it an excellent choice for professional concrete and masonry protection.
