Silicone problem

[JOHNJO14]

At the back of the sink in our kitchen there is a white tiled wall, the tiles run along for a length of about 18 ft x 2ft high.
The bottom of the tiles has white Silicone running along them & in the area behind the sink the water has rotted & dirtied the Silicone, some of it has broken away. Some time ago we had the same problem & we got a Tiler to come in & redo it with fresh Silicone, but now its gone bad again.
I don't want to put this Silicone on it again as it doesn't last very long & its expensive getting it done by a Tiler, & so i am wondering if there is someone on here who can advise me on what to do.
I have been thinking about a narrow trim or something, if there is such a thing, that i could possibly fix to the bottom of these tiles ?, or any other proposal on how to deal with this.
Any help will be appreciated.
John

Hello John and welcome..

You need to remove all of the mouldy silicone before re-sealing or the mould will just grow back..

Silicone eater from any good DIY store will remove it..

but firstly what kind of work tops do you have and what brand of silicone was used before.?

Pop into b&q and get some silicone eater and remove all of the silicone and then when cleaned down renew

Use a silicone with anti-mould and suitable kitchens

I use mapei ultramastic shower was done 8yrs ago still no mould between 8 -10

mapei ultramastic does not go black, as Deano says mask it first. Sounds like cheap silcone was used. mapei is about a tennerish.

Thanks a lot, I will get this. I ahve the same problem with our shower. All around the bottom of the tiles where they meet the base is as black as soot, has been redone twice before by a Tiler, but it constantly looks dirty after a short time, would this Ultramastic be ok to put on that also ?
Thanks again, John
