Potassium Silicate Coatings

 is a premium, mineral-based silicate paint (also known as a true mineral paint) that chemically bonds with masonry substrates at the molecular level through silicification. Unlike conventional latex or acrylic paints that form a surface film, it penetrates and reacts with the mineral surface to create a permanent, integral finish that becomes part of the substrate itself.
Key Benefits

• Exceptional breathability — Delivers up to 92% vapor permeability when applied to bare masonry, allowing moisture to escape while preventing trapped dampness, efflorescence, and freeze-thaw damage.
• Superior durability & longevity — Never peels or flakes; forms a strong chemical bond that withstands extreme weather, UV exposure, and decades of service with minimal maintenance.
• Water repellent — Combines traditional silicate technology with silicone for active water beading and repellency.
• Mold, mildew & fungi resistant — Its naturally alkaline nature provides built-in protection.
• Colorfast & fire retardant — Remains stable under sunlight; non-combustible with zero flame spread and no VOCs.
• Eco-friendly — Low- or zero-VOC formulation ideal for sustainable and historic restoration projects.

Where It Is Applicable
It is ideal for both interior and exterior vertical surfaces on all sound substrates, including:

• Brick, concrete, limestone, brownstone, sandstone, and terra cotta
• Historic masonry and modern structures
• Plaster and previously painted surfaces (though optimal performance is achieved on bare masonry)

It is not recommended for wood, metal, plastic, horizontal surfaces, or areas where water can pool. For best results, apply to clean, dry, absorbent masonry with a short-bristle brush.
