Bond It GP200 General Purpose Silicone Sealant White 310ml – Waterproof LMA Sealant

Bond It GP200 General Purpose Silicone Sealant White 310ml is a contractors-grade Low Modulus Acetoxy (LMA) silicone sealant designed for reliable sealing, glazing and weatherproofing across a wide range of indoor and outdoor applications.

Its flexible, high-viscosity formula guns out smoothly and tools to a clean high-gloss white finish, making it ideal for sealing around uPVC windows, doors, glass, ceramic surfaces, painted timber, aluminium and glazed brickwork.

The cured silicone forms a durable, waterproof rubber-like seal that helps protect against moisture, draughts, driving rain and general weather exposure. An integrated anti-mould fungicide helps resist black mould growth, making GP200 particularly useful in bathrooms, kitchens and other humid areas.

The sealant offers good movement accommodation, helping joints cope with normal expansion and contraction without cracking. It also provides strong resistance to UV light, ozone and changing outdoor temperatures, making it suitable for both interior and exterior use.

GP200 typically skins over in around 10–15 minutes and cures at approximately 2mm per 24 hours, depending on conditions and joint depth.
