SIRAMICO COATINGS Masonry & Render Sealer

Siramico Coatings Masonry & Render Sealer – Breathable, Invisible Protection for Exterior Surfaces Protect your render and masonry the smart way with Siramico Coatings Masonry & Render Sealer. 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. It allows your surface to fully breathe while preventing rainwater ingress, helping 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. There is no change to colour, texture or appearance—making 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
