    Default Need some advice with bathroom tiles/silicon

    Hi guys,

    I have a frameless shower in my bathroom.

    Recently my wife noticed (ie. where the wall tiles meet the floor tiles inside the shower) that the silicon comes away. It still there but look's like its not adhered properly. As if you pull the silicon with your hand it comes away from the tiles and you can see underneath. Other than that its still intact.

    I had another tiler come in to do some other work in the laundry but he is reluctant to touch it as he didn't lay the tiles in the bathroom.

    He told me to try and contact my other tiler to have him fix it but I cant get hold of him.

    Anyway this other tiler indicated that if I leave the silcon the way it is I may get water damage long term. Or may even have it now and will have to have to have the floor and wall tiles removed and done again so I am obviously worries about it.

    What is the likely hood that I do have damage ? As my floor tiles are layed on a concrete slab and the bathroom was water proofed and I also used waterproof plaster on the walls.

    Is there any way that I can actually check if I do infact have any damage.

    Would you recommend that I re-apply the new silicon myself and what is a high quality product I should look at using.

    As the tiler has suggested that I need to use a guy that specialises in corking.

    Thanks

    If it's a shower that's been (properly) waterproofed in about the last 20 years, there should be no chance of water damage. That's all taken care of by the waterproofing membrane that's hidden out of sight behind the tiles.

    Silicon, like grout and tile, really plays no part in waterproofing, it's just there to fill a gap that undergoes contraction/expansion as the building moves.

    Just strip it off, scrape the remainder off with a razor blade, clean the area really well (scrub with strong detergent solution, rinse off with water, wipe over with a cloth wet with metho) and use some Selleys or Sika brand silicon.

    Aside from the tap test (tap on the tiles and see if any sound drummy) there's not really any non-destructive test for water damage. If you have an inspection camera you could possibly look inside the wall from the other side after drilling a small hole, assuming you have access to it, that is.

    Yes it is a bit tricky for a novice. An easier product is http://www.bostik-us.com/bostik%C2%AE-tub-tile-caulk

    Use masking tape for a neater joint. As Random said cleaning out the old is most important as nothing

    use a paddle pop stick to shape and soapy water in a spray bottle as a release agent, not to hard to get a professional finish.
