Features & benefits
Bostik Home is a clear, one part acetoxy curing high quality general purpose silicone sealant that provides a permanent flexible, durable, watertight seal for general purpose sealing in and around the home. The sealant is extremely resistant to UV radiation, weathering, ageing and water, and offers excellent chemical resistance and is unaffected by diluted acids and alkalis, soap and household detergents. The sealant remains flexible over a wide range of temperatures from -45°C to 150°C. It also performs as an excellent adhesive on non-porous surfaces where an elastic gap-filling bond is required. It has a non-sag rheology and can be applied to vertical surfaces. Bostik Home contains a fungicide and resists mould growth. Ideal for sealing, bonding, and mending DIY tasks in and around the house such as sealing around bathroom and kitchen fittings, bonding up signboards, insulating appliances, fixing leaking plumbing, etc.
Not suitable for alkaline surfaces such as concrete, fibrous cement, asbestos, plaster and marble. Not suitable for some metals i.e. mild steel, lead, copper, tin, galvanized iron, brass or zinc as it may cause corrosion. May become discoloured in contact with some organic elastomers, which tend to bleed oil or solvents into the silicone, e.g. EPDM, APTK, Neoprene and Bituminous surfaces. Not suitable for mirrors as it will de-silver the mirror backing, affecting the front appearance of the mirror. Not suitable for contact with natural stone i.e. marble, granite, quartzite as it may discolour the surfaces. Will not adhere to some plastics such as polyethylene, polypropylene and Teflon. Do not apply sealant when relative humidity is below 10% - cure rate will be affected.
NOT SUITABLE FOR FISH TANKS (contains a fungicide).
NOT paintable.

FAQs
How do I store my silicone?
To maximize the shelf life of an opened silicone cartridge, we recommend that the nozzle be removed and a piece of plastic placed over the cartridge tip after which the nozzle must be screwed back on. A large screw inserted into the nozzle tip also helps to extend the life. Store in a cool environment.
How do I remove cured silicone?
Cured sealant must be removed mechanically with a sharp knife or chemically with Bostik Silicone Stripper. Always test on a small surface first.
