    It sounds like the silicone was poor quality or not meant for bathrooms.

    I would remove it and buy best quality bathroom sealant. Don't buy any of this 99p rubbish thats around these days.

    I agree most of the cheap silicon isnt all that good, but good quality only about 2 to 3 more tends to dry really quickly and has better mold resistance in it.

    Before you replace it, try rubbing it with lemon juice added to water. That might work.

    Re-seal with a mould resistant silicone. Most bleaches and cleaners turn the mould orange.

    Yes. It'd be easier to re-seal (just strip it away, clean the area and then pop some new sealant down - it's actually a pretty quick job).

    Also if the sealant is round the bath or shower tray then a good piece of advice I was given is that if it's a bath - half-fill it with water so that the sealant will 'set' with weight in the bath (and therefore will not pull away when you climb in), for a shower tray, just put something of weight in it too.

    Cheers

    ... For builders / decoraters - yes! For the general public... er... well... I didn't know it the first and second times I sealed the bath!

    Use this:

    http://www.hi-glitz.com/hd-ms.html

    HG Mould spray. We use it on our shower seals once a month and it's like magic and doesn't stain anything. Most DIY stores stock it for about 5.

    As suggested, it is better not to use cheaper sealant. But even the most expensive silicone sealant will eventually get mould on.
  • DSR
    Thanks to you all for all your excellent advise.
    I will try using lemon as suggested by Dee2005 and if that does not do the trick I will reseal using a top end silicone seal.

    roll up a piece of kitchen roll, and lay along the sealant, then pour bleach on top, and leave for 10mins - then just lift the kitchen roll off, bin it, and then give the sealant a quick swish with some water - brings it up like new, every time

    why does my sealant always come off when it gets wet after a couple of times? :confused:
  • jockettuk
    what the best way to strip the sealant using a knife etc might damage the bath!

    If your silicone comes off when wet, it's probably not been put onto a clean surface to start with and has cured without fully adhering to the surface, or it was poor quality silicone.
    You need to remove it completely, clean the area to be redone. Let the area dry out. Fill the bath half full. Then reapply the new silicone.

    As for removing it, this is difficult to describe and everyone does it differently.
    I use a new stanley blade to cut along the tile edge. I then cut out as much as possible with the blade. Then I have a sharp narrow wood chisel that I hold upto the silicone edge on the bath and carefully run it along the bath under the silicone, this lifts it up. You can scrape as much as you like providing the new silicone bead will cover it up.

    I'm not sure why silicone needs to be cleaned. Mines good stuff and has been on for about 5 years. Its not discoloured in any way.

    I think if you remove as much water from the area after your shower/bath it helps.

    I always use the drying towel to give the shower cubicle a quick rub down to remove water after my shower. It takes me 15 secs to do and my cubicle looks the same as when I made it 5 years ago. Plus I've never had to bleach my silicone.

    I always do dry the bathroom sides everytime it gets wet, but eventually the sealant comes off when i wipe it dry. I have'nt replaced the sealant from the ones the previous owner put on, but i did try to do it once only to find out that i bought the wrong thing - it looked like cement and crumbled away when it got wet!!!
  • jockettuk
    i want to remove it as eventually i will sell my house and it will look tidier without the mould on lol

    Silicone remover is OK to tidy up after removing most of the sealant with a knife. I don't think it would work too well if applied direct to full thickness sealant, it does say on the instructions on the one I have to remove as much sealant as possible first.

    Last time I used a wide snap-off blade knife (allows a longer blade and better angle than a stanley knife) and a window scraper.

    I used a bleach spray afterwards to clean any mould from the gap, then wipe down with meths to remove any residue and help dry the gap.

    The shape of the new sealant should not be recessed or concave so that water will sit on it as that can lead to mould.

    Thanks - managed to get most of it removed without the need for a silicone remover. Anyway, I just wondered whether it is ok to give it a second coat of sealant the next day to make absolute sure or is that not usually necessary if it is done right the first time?
    Is there any harm in doing it?
