Silicone Sealant and Sealant Gun

Extend the life of your garden building by applying silicone around the windows to prevent water ingress. This silicone can be used internally and externally and creates a water tight barrier that prevents water leaking into the joints of your garden building. Sealing around the windows of your garden building helps to prevent wood rot but also helps to reduce draughts. The fast setting silicone is ideal for use on sheds, summerhouses, greenhouses and log cabins. The silicone will remain permanently flexible and contains a fungicide to prevent mould.
