Silicon 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 Silicon running along them & in the area behind the sink the water has rotted & dirtied the Silicon, 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 Silicon, but now its gone bad again.
I don't want to put this Silicon 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 Silicon before re-sealing or the mould will just grow back..

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

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

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

Use a Silicon 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

John, is your kitchen tap one of those mixer taps that swivel around? They can quite often leak. Do you think this could be part of the problem? If you are dead against Silicon then how about bath trim? I saw some the other day in Focus Diy, but I'm sure B&Q and the other sheds have the same product. This trim is stuck to the wall tiles and the work top. However, the walls & worktop have to be really dry or else it won't stick. Failing that I have in the past used Homelux plastic trim & Silicon behind a kitchen sink. This is because the worktop had partly rotted away. Good luck. Sean

also this is not bad [video]http://www.*************/p/no-nonsense-sanitary-Silicon-white-310ml-pack-of-12/38910[/video] screw-fix no nonsense

any silicon used where water is present should use a sanitary silicon. screwfix give a varied choice about a tenner a tube.i use microban keeps mould free for years. there is a plastic moulding that clips on to a fixed rail it is expensive and crumbs etc still work under it.i would go for good sanitary silicon its cheaper and easier to maintain.best of luck

Thank you all so much, the grout between the tiles in the shower has also gone mouldy (from the bottom row of tiles up to the 4th row) Is there anything i can use to clean this, or should i regrout them.
