Best mould resistant Silicon

[Jrterror]

Hi.
I'm just wondering, in your experience which are the best mould resistant Silicon sealants?
I used one to sort the tired Silicon in our shower about six months ago and already it has a speck of mould, so I don't want that to happen with the brand new shower that I'm installing.

So, have you guys ever gone back to jobs and found that silicones you have used are still looking great, even year laters?

If so, which ones?

What colour are you going to use?

Hi. Grey.
Whilst here. Should I Silicon all corners and areas where the tiles meet the tray first and then grout. Or visa versa

I use Dow corning for white, colours are usually Mapei or Ultra.
I tried BAL Silicon the other week and found it really sticky to use I didn't like it but it may well be the best anti mould one.

By no means!
You must always grout first, pump plenty of Silicon at the base of the wall profiles of shower enclosure where it meets the tray.

Hi.
Do you mean before tiling, fill the gap between the walls and the tray. If so, already done.
Out of curiosity, why grout first. What's the idea behind the particular process

thanks again

You must always grout first.

That's debatable Bob.

I suppose its each to their own, I see Silicon as a finishing touch always after grout for me.

Thanks for your input.
Would you not say that Silicon around the edges of the shower area are not so much a 'finishing touch', but instead the primary method of sealing the abutments of the wet area.i.e. corners and where tiles meet the tray.

Umm, really interesting. I'm day looking at a shower now, and I wonder if if grouting first, being careful to not spill into corners and where tray meets tiles would be wiser, just as you say.

I always use the Silicon sandwich technique. If tiling a shower or bath I will Silicon first (any colour because you are not going to see it) then tile then Silicon again. As for corners, just the finishing touch is enough as its a movement joint. I normally use Ardex Silicon and had no issues.
