How to Seal Around a Bath
Tuesday, December 6th, 2011DIY enthusiasts often struggle to achieve a decent seal between the edges of a bath, shower tray or basin and the wall. If a seal is allowed to open up, the walls and the floor can suffer from moisture damage. This means that it is essential for a bath, shower tray or basin to be permanently sealed.
In the event that you need to seal small gaps of approximately three millimetres in width, silicone mastic is the material of choice to use. This is a flexible sealant that you squeeze evenly into the gap from a tube which is fitted into an application gun. Once the sealant has been squeezed into the gap, it is smoothed with a wet dowel. The mastic is available in colours to suit your bathroom’s decor.
Larger gaps can be sealed using quadrant tiles or else special strips of plastic bought for the purpose. Whichever you choose, they’ll need to be bedded on mastic so that a waterproof seal is assured.
Damp in bathrooms is an ongoing problem but as long as all edges are properly sealed there should be no danger of water getting into the cracks and causing damage.
