Dowsil 785 Sanitary Silicone Sealant 310ml White

The Dowsil 785 is a one-part sanitary silicone sealant designed for creating durable, waterproof seals around bathroom and kitchen fittings. Its primary function is to prevent water ingress and maintain hygiene in wet areas by sealing joints between surfaces like baths, showers, sinks, urinals, and ceramic tiles. The formulation is specifically engineered for environments where moisture and bacteria are prevalent. Key features include the incorporation of a fungicide to actively resist mould and mildew growth, which is a common issue in damp sanitary spaces. It offers a fast cure time, becoming tack-free within approximately 30 minutes of application, allowing for quicker use of the sealed area. The sealant also provides excellent flexibility with a joint movement capability of +/-20%, accommodating natural expansion and contraction of materials without cracking. It conforms to the ISO 11600-F-20LM standard for sealants and is tested to ISO 22196:2007 for its antibacterial efficacy against pathogens including salmonella, E. coli, and MRSA. This sealant is best suited for DIY enthusiasts, homeowners, and professional tradespeople undertaking bathroom renovations, kitchen installations, or general maintenance. Its white colour blends discreetly with most sanitaryware and tiling. Being suitable for both interior commercial and domestic use, it is a practical choice for creating long-lasting, hygienic seals that are easy to apply from a standard 310ml cartridge using a caulking gun.
