Everbuild Builders Silicone Sealant

The Everbuild Everflex® 450 Builders Silicone Sealant in Brown, supplied in a practical 310ml cartridge, offers the perfect solution for applications where a rich, warm tone is required to complement wooden frames, brown PVCu installations, and traditional building materials. This brown variant is particularly popular for heritage projects, residential properties with wood or brown finishes, and situations where a subtle, coordinated appearance is essential for professional results. As a low modulus, oxime cure RTV silicone sealant, it provides excellent adhesion to both porous and non-porous surfaces without priming, whilst conforming to BS5889 standards for quality assurance. The high viscosity formula delivers outstanding tooling properties and cures quickly to form a permanently flexible, high strength waterproof seal. The brown colour makes it especially suitable for perimeter pointing around wooden and brown PVCu window frames, sealing timber components, and general building applications where aesthetic coordination is paramount.
