Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
- Watch for new gaps as the house dries out
Do not stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you so report it promptly.
