Everbuild Builders Silicone Sealant

The Everbuild Everflex® 450 Builders Silicone Sealant in Oak, supplied in a 310ml cartridge, offers the ideal solution for applications involving oak and light wood finishes where perfect colour coordination is essential. This oak-coloured variant is specifically designed to blend seamlessly with oak window frames, oak PVCu installations, light timber components, and traditional joinery work, providing an almost invisible seal that maintains the natural aesthetic of premium wood installations. This low modulus, oxime cure RTV silicone sealant adheres excellently to both porous and non-porous surfaces without priming, conforming to BS5889 standards for quality assurance. The high viscosity formulation delivers superior tooling properties and cures quickly to create a permanently flexible, high strength waterproof seal. The oak shade is particularly valuable for high-end residential projects, heritage restoration work, and any application where maintaining the appearance of natural oak or light wood finishes is paramount to achieving a professional, sympathetic result.
