Bathroom & Sanitary Sealants

Learn more about bathroom and sanitary sealants

Bathroom and sanitary sealants are used to form a flexible seal around baths, showers, basins, sinks and other wet areas. For trade work, the main checks are simple: the joint size, the substrate, how much movement the joint needs to take and the finish you want.

Typical uses

• Sealing around shower trays, baths, basins and sinks.

• Finishing joints in wet areas where a flexible seal is needed.

• Choosing bathroom and kitchen silicone where the same type of sealant works across both areas.

• Replacing bathroom sealant on maintenance and refit jobs.

How to choose the right bathroom or sanitary sealant

• Start with the joint. If you need a flexible seal in a wet area, bathroom silicone is the usual place to start.

• If the joint runs across different materials or needs more movement tolerance, a hybrid sealant may be a better fit.

• Sanitary silicone sealant is commonly chosen for wet areas where mould resistance matters.

• Select a multi-purpose sealant when you need to use it in a variety of environments.

Before you order

• Check the joint size, the substrate and how much movement the joint needs to take.

• Confirm whether you need sanitary silicone sealant or a multi-purpose sealant.

• Pick the colour that suits the finish, such as clear or white.

• Check the pack format, including gun grade cartridges for standard sealant guns.
