Everbuild Premium+ 450 Builders Silicone Brown 300ml

Everbuild Premium+ 450 Builders Silicone supplied in a 300ml cartridge is a low modulus, neutral cure silicone sealant engineered for general construction, perimeter, and façade applications. It provides excellent adhesion to a wide range of building materials including glass, metal, wood, PVCu, and polycarbonate, forming a durable, flexible, and weather-resistant joint. The non-corrosive formulation ensures compatibility with sensitive metals such as copper, zinc, and lead, while maintaining long-term elasticity under movement conditions up to ±25%. Ideal for internal and external perimeter pointing, expansion joints, and panel sealing, it performs reliably in all building environments. The brown colour offers a warm, complementary tone for use with timber, brick, and darker architectural finishes.
