This advanced, water-based impregnating formula penetrates deep into porous surfaces to provide long-lasting water repellency without sealing the surface or trapping moisture. Unlike traditional sealers that form a film or leave a sheen, this breathable treatment works from within, allowing your surface to fully breathe while preventing rainwater ingress. This helps to reduce damp issues, staining, dirt build-up, and organic growth such as algae and mould. Once applied, the sealer dries to a completely invisible, natural matt finish, with no change to colour, texture, or appearance. This makes it ideal for both modern decorative renders and sensitive heritage or listed buildings where maintaining the original look is essential. Designed for ease of use, this product can be applied with a pump sprayer or roller and typically requires just one coat. On more porous surfaces, a light second application may be needed. With coverage of approximately 30m² per 5 litres, it offers reliable and cost-effective protection across a wide range of substrates. Suitable for use on K-Rend, silicone and monocouche renders, as well as traditional sand and cement, brickwork, concrete, natural stone, sandstone, limestone, granite, slate, flint, and lime pointing. Key Benefits: Deep penetrating, breathable waterproofing. Invisible natural matt finish – no colour change. Water-based, low odour, and low VOC formula. Helps resist damp, dirt, pollution, and organic growth. Suitable for modern and traditional surfaces. Ideal for historic and listed buildings. DEEP PENETRATING WATERPROOF PROTECTION: This impregnating sealer penetrates deep into the substrate, forming protection from within without creating a surface film. Provides excellent resistance against rainwater, UV exposure, damp, dirt, grime, pollution deposits, and organic growth. FULLY BREATHABLE & WATER-BASED FORMULA: A high-performance, breathable impregnating sealer designed for all porous masonry and render surfaces. Water-based, solvent-free, and low VOC, ensuring low odour and fast drying. Suitable for both new builds and older, historic, or listed properties. INVISIBLE NATURAL MATT FINISH: Maintains the original look of your surface with no change in colour, sheen, or texture. The sealer is completely invisible once dry, preserving the natural appearance of render, brick, or stone. EASY ONE-COAT APPLICATION: Apply in a single coat for most surfaces. For highly porous areas, apply a light second coat after approximately 30-60 minutes. Coverage rate: around 5 litres per 30m² depending on surface porosity. Suitable for use with a pump sprayer or masonry roller. SUITABLE FOR A WIDE RANGE OF SURFACES: Ideal for modern renders including K-Rend, silicone, and monocouche renders, as well as traditional sand and cement. Also suitable for brick, concrete, natural stone, sandstone, granite, slate, limestone, flint, and lime pointing. Will not restrict breathability, making it ideal for heritage properties.
