Showers and bathtubs require the application of a sealant made from silicone. This is necessary to prevent water escaping across or under the floor or behind the sanitary ware. Applying it is not tricky, but removing it may be harder.
The removal of silicone sealant is required not only for repairs, in anticipation of a bathroom refit, or as a tidying up exercise after the installation of new sanitary ware; it’s also necessary when the sealant itself needs replacing. Depending on the ventilation, moisture levels and humidity in a particular bathroom, this removal and replacement exercise may be a fairly frequent occurrence.
Engage a professional?
Regardless of the quantity of sealant that needs to be removed, the obvious question is whether to call in a tradesperson. Some people may want to engage professional help. In that case, Checkatrade is a good source of reputable and recommended tradespeople.
