Shower tray reseal

billiepiper14

Hi
im a very basic DIYer as your about to find out but with the below shower tray if I wanted to reseal because of mould in each corner would I simply rip off the strip of sealant and use a caulking gun to put another strip of seal down ? Worried about disturbing it incase I don’t do it right and creates a leak through kitchen sealing. I can’t clean the mould off though so needs changing. Thankyou

Roll up some tissue sausage’s with bleach added(wear gloves) and leave overnight hey presto mould gone.

I resealed mine with some trepidation but it was fine.

Got the mould back in the same place eventually though, probably because there's an air gap so it gets cold and damp. 

I'd try mrbusters idea first.

I tried Miltons fluid which bleaches most things but not this, and mould remover and bleach which did half a job but I havent' tried that way. I'll give it a go.

Unfortunately I think that unless you are prepared to dry the shower every time its' used this is going to happen.

I bought Mould Magic from Must Have Ideas UK. Was a bit sceptical but it really does work. It's better than HG Mould Foam which I'd used before, as it's a gel, so it tends to stay where you put it rather than running off.  It's a far easier option than stripping out the silicon and replacing it, which we did several times in a previous home.

Yes, but make sure that bleach contains 'bleaching agent'.
E.g. this Tesco bleach doesn't:

"Ingredients: <5% Anionic Surfactants, Non-Ionic Surfactants. Also contains: Disinfectant Sodium Hypochlorite 4.6g per 100g, Perfumes. AL: Other liquids to be applied undiluted."

And from my experience correct thick bleach works even without any tissue.

If you are going to redo the silicone, some are definitely better than others at resisting mould.

I last redid the shower in Dowsil 785 bacteria resistant (also mould and mildew resistant) sealant, this was a bit more expensive than other but much better than the previous cheap stuff.

I'd also consider drying the shower (especially in the corners where mould develops) after each shower with a towel.

This has always worked for me, even the stubburn mold disappears after doing this over two days.

I don't use direct bleach, I use Astonish Mould & Mildew Remover Spray and it's great.

The old sealant is very unlikely to come off in long strips. As replacing sealant is a fiddly job for novices to get right,  I'd recommend following the advice re- killing the mould.

IMHO, the best method for a shower is to use a tray with an upstand. This way you don't need silicone along the bottom. A New Zealand chippy I worked with a few years ago told me it's the only way it's done over there. No problems with leaks or replacing the silicone.
