Hi, we renovated our bathroom and within 6months we noticed the silicone lining has gone mouldy. :(
Has anyone experience this? Would be greatful with some pointers on how to fix this issue.
Thanks in advance.

Do you mean the silicone gel that fills the holes? If so, you can spray with Janola and it will remove the black spots if left to soak. I had to replace all mine and use a bathroom silicone which resists mould. Messy job.

Hi fhpottery, it's the silicone that lined between the shower wall and shower tray.
Also we can see the silicone is also sort of coming off apart from being mouldy.
What bathroom silicone did you use that resists mould and does it work? We are wondering why the silicone gone mouldy.

Was it installed by a professional? You should not be able to see any silicon inside the shower. Also mould occours in silicon when it has been spread by fingers. The particles of skin get into it and in time causes infected silicon.

If it was done by a pro I'd be calling them back otherwise I've saved this link for when I do mine.
There's a few do it yourself video's on youtube too.

I have resealed several showers and it sounds like a rough initial job as you should not be able to see the silicon in the first place. I assume you mean the house wall as opposed to the shower glass wall. The correct silicone should be applied from the OUTSIDE of the shower if it is the glass wall mouldy, but if it is the house wall then the best option I think is to remove as much as you can without damaging the bottom of the liner and shower tray / dry thoroughly and reapply (Using gloved hands). Ensure you use the correct sealant and most of all ensure a good 24 hrs to dry properly.
The correct method when first applying the liner on the house wall to liner is to apply a thick bead of sealant about 25mm up from the top of the base of the shower tray so that it will never be seen.

Unfortunately we no longer able to get the initial plumber to come back to redo this job. We did not expect to see silicone gone mouldy, but survivalkiwi is right about silicone spread by finger because one of us remember seeing the plumber did it! Now that probably makes sense.
Thanks groovie1 for the link & Ceebee2 for your comment, sounds like we need to redo the silicone! Would you be kind enough to elaborate on this - "To apply a thick bead of sealant about 25mm up from the top of the base of the shower tray so that it will never be seen" Thanks.

That shower door has the silicon on the inside and you can see the silicon around the base. Why did a plumber do it? It is usually the builders job or now days we use a specialist. If you did pay a pro to do it you should call him back because that is piss poor. They are not rocket science to install but do have to be done correctly.

You will need to pull it apart to redo in correctly. I redid one last week that was never done properly the first time round. The chances of getting the lining off without it breaking it are about zero. So it ill be an expensive fix.

That's exactly the reason why we will not be asking the plumber to come back and fix the job even if he's here.
Do we scrap off the silicone under the frame on the inside and reapply on the inside or outside?
Just a quick question, in our case, would it be better off to use clear or white silicone?

You really need to pull it apart and redo it. Was it a second hand screens as I have not seen matt aluminium ones since the 80s. I used white silicon on my house with crome metal work.but spent a lot of time masking it so it looked neet.

It was a new shower. Have re-checked - it's probably the photo not showing very good that makes the frame looks aluminium, they are actually chrome metal. Good idea to mask it! Thanks for the tip.
Once we get rid of the silicone under the frame/shower door, should we be applying new silicone back on the same spot inside under the frame or outside as you were commenting on?
Thanks for being so kind and helpful.

I am really puzzled as to why a plumber would be installing a shower. Having worked for builders and built several times, we always use a shower installer. OP, have you checked for leaks around the shower?

Bleach does not kill mould, it just whitens it. Remove and use a mould resistant silicon.

Use no silicon while installing the doors. Then mask and then silicon. Only around the outside. So that's between the aluminium and the liner and the aluminium and the tray only. I use a rubber glove when I am smoothing it out. I keep the finger wet. And keep going over it until it is nice and neat. Make sure the silicon you buy is the correct one for the job. You local hardwear store will help you with your choice.

Oddly enough, the vast majority of mould killers including domestic & commercial cleaners, use varying strengths of bleach as the active ingredient. Most common type of Bleach = sodium hypochlorite = Chlorine http://blacktoxicmolds.com/bleach-kill-mold.php This is a well informed doco that needs to be read entirely If you only read parts of it, then you will get an unbalanced view. Theres pro's & cons for both Chlorine & oxygen bleach products

My daughter cleaned our grout and silicone in our shower with DOMESTOS bought at the supermarket. Works a treat so easy
