Anqa SL 70S Water-Based Siloxane Water Repellent

Anqa SL 70S is a high-performance, water-based siloxane treatment specifically engineered for the protection of porous mineral surfaces. Unlike traditional sealants that form a film on the surface, this product penetrates deeply into the substrate to create a durable, hydrophobic barrier. This technology ensures that water is repelled from the surface, preventing moisture ingress, efflorescence, and freeze-thaw damage, while allowing water vapor to escape, thus maintaining the natural breathability of the material.

Key Features & Benefits

• Deep Penetration: Siloxane molecules bond chemically within the pores of masonry, concrete, and stone, providing long-lasting protection from the inside out.
• Breathable Protection: Repels liquid water but allows vapor transmission, preventing trapped moisture and internal structural stress.
• Invisible Finish: The treatment is transparent and does not alter the color, texture, or appearance of the treated surface.
• Easy Application: Being water-based, it is easy to apply by spray, brush, or roller and cleans up with water, making it a safe and convenient choice for contractors.

Recommended Applications

This product is ideal for protecting exterior and interior masonry walls, concrete structures, natural stone facades, and porous building materials from rain, humidity, and saltwater splashes. It is particularly effective in regions with high rainfall or coastal environments where salt corrosion is a concern.
