Give your work a waterproof finish with our great range of silicone sealants, including waterproof expanding foam, gap filler, and weatherproof sealant. We stock popular lines of professional-quality expandable foam and waterproof sealants by leading manufacturers like Bostik, Dow, and Soudal. These trusted brands produce expanding foam fillers and more products that effectively seals gaps with a durable, lasting finish.

For ease of application, choose a cartridge gun, compatible with many with sealants. Expandable foam is a versatile way to fill irregular spaces around new plumbing installations and anywhere else where effective waterproofing is required. In addition, see our range of adhesives and adhesive tapes, all of which can fix your work in place.

Sealants can be used throughout interiors and some outdoor applications too. Many are ideal for kitchens and bathrooms to seal around sinks, baths, and shower trays. Waterproof silicone sealants are available in white and clear so you can match the colour scheme you are working with. Other colours are also available, including grey sealant to match grey tiles.
