Bostik Fireseal Silicone Sealant White

Bostik Fireseal Silicone Sealant. A fire resistant silicone sealant that provides excellent adhesion to a wide range of substrates including masonry, will not slump in joints up to 25mm wide. Suitable for internal and external use. Can be used in both movement and non moving joints, i.e. for open butt joints in screens, partitions and structural walls. Shown to be effective as a service penetration seal for both metal pipes and cables, particularly where movement is a factor, i.e. hot/cold water pipework.
