About Sealants

Sanitary Sealants

Silicone sanitary sealants ideal for sealing around sanitary units and non-porous surfaces. They provide excellent adhesion to a variety of substrates including ceramics, plastics and vitreous enamel. Once cured, sanitary sealants are water resistant and will retain high performance qualities throughout their long service life. The main uses of sanitary sealants are: sealing around all types of sanitaryware including baths, basins, showers, toilets & glazed tile surrounds.

Fire & Acoustic Rated Sealants

Acrylic, cement, silicone and foam fire & acoustic rated sealants formulated to form an acoustic and/or fire rated intumescent barrier. For sealing gaps between plasterboard walls, floors and ceilings, dry linings, and kraft lined insulation boards, amongst other things, where sound insulation and fire protection is required.

For example, Plumba Flue is a one component, high temperature acetoxy silicone sealant suitable for use on non-porous surfaces and ideal for sealing gas flues.
