Bathroom sealant question

[rajanm]

Hello all,

I had my bathroom done about 6 months ago and so far everything is holding up well...no mould, the tiles are still on the walls etc!

The only thing I've notice is a very very narrow gap appearing between the sealant around the bath and my wall tiles. It's probably not much more than 1mm, possibly even less but it is noticeable - it's about 5cm long.

I had previous issues with water leaking through sealant and don't want a repeat - I also would rather not get the sealant replaced as the rest of it is as good as new. My question is, is there such a thing as a way to touch up sealant? i.e. a tube where you can apply a really really thin layer of sealant? Like I said, it's a very small gap but it would be good to close it up...

Silicon takes to Silicon very badly. I reckon your bath may have dropped slightly. Did the plumber fill it with water before he sealed it? I'd cut about 10cm away and redo it. Make sure it's bone dry as well. Should smooth in nice enough.

I'd remove and re-do all the Silicon around the top of the bath, as there's clearly more movement than the Silicon can handle. There may only be 5cm now, but how long before the rest goes?
As Dan said, fill the bath with water before applying the Silicon. 😉
I usually run a Batton under the lip of the bath, as it stops it dropping.

The other reason could be the surfaces weren't degreased/cleaned before the silicon was applied. So all as danmasey says. Bone dry is the most important thing! Whipe area either with meths or acetone. If meths, makes sure it doesn't stain the grout (keep it away). Leave to dry for a minute. Mask the area off with masking tape or similar. I like Duck tape. And then in you go with the silicon. If you've not played with silicon before, have a practice well away from stuff you like. Look at some YouTube videos. Remove the tape as soon as you're done.

As above, might also be worth checking legs are all tight on bath, as If that's the problem it's pointless re sealing as it will only happen again.

As above , over flexing of a bath can result in split siliconing.... if the bath flex's then try to strengthen it up....


Also before you re-new the Silicon once removing the old , make sure the area is dry or the new Silicon will not adhere..
