To prevent damage by moisture and possible mould, applying silicone sealer to sanitary fittings in a bathroom should be done when installed, and again when the sealer fails.
Even when professionally applied, sealer has a life of about 18 to 24 months in a bathroom and when it starts to pull away from fittings it needs to be removed and replaced.
Replacing the silicone seal around bathtubs, sinks, showers and even toilets should be done as soon as the old seal starts to fail or becomes mouldy. This seal is important, as it prevents water ingress into plaster and masonry, which could result in expensive repairs or an outbreak of mould.
1. To remove old silicone sealer, use a sharp craft knife to loosen the top and bottom edges before peeling this off. Any stubborn sealer can be removed with acetone (nail polish remover) and a soft cloth.
2. Apply a strip of masking tape above and below where the silicone sealer is being applied. This makes for easy clean up easier and leaves a nice, neat edge.
GOOD TO KNOW
Silicone sealer is available in a variety of colours, as well as transparent, so choose the one that will be the least visible once applied.
Buy the product in a cartridge and use a caulking gun to apply the silicone sealer. Most products now come with a cap that can be used to extend the life of the product in storage.
3. A caulking gun allows you to squeeze out a single, solid bead of silicone in a thin line. Have a piece of tissue paper or kitchen roll handy and use your fingertip to wipe away any excess sealer, wiping this into the tissue as you work.
4. Remove the masking tape before the sealer has time to cure and you will be left with a clean line of silicone sealer that will protect your countertops from moisture.
Whether around a bathtub, basin or in a shower, removing and replacing the silicone seal will prevent future expensive repairs caused by water damage.
