    Is a small crack like this in a shower tile an issue ?

    We have a wet room style shower and I see one of the little tiles has a crack, it’s away from the shower head so wouldn’t have any direct flow of water but could it be an issue and if so what best to seal it ?

    If it were me I would get it bone dry(use a hair dryer) get hold of some waterproof epoxy resin and fill it. If left it might just seep through in time.

    If you can see the ends of the crack, stop drill them with as small a tile drill as you can find. A: this will hopefully stop the crack propagating, and B: you can use the holes to inject some clear sealant underneath and into the crack.
    This is on the assumption you don't want to get the tile up and replace it.

    A smear of some quality super glue could do it.

    Spot on - some two pack epoxy is the way to go, an easy fix. Definitely not silicone as won't last and will quickly attract mould at that thin an application.

    Original Araldite is what I would use, but be sure to dry the tiles 100%. Also worth drilling small holes at the ends of the crack to precent the likelihood of propagation. Araldite bonds very sell to ceramics, ideal way to seal the crack and add strength.

    I’d be inclined to just use tile sealant, the stuff that’s like water and painted on the likes of travertine or limestone tiles. It will definitely flow enough to fill the crack and seal it and capillary action will help too.

    Anything viscous such as araldite will only sit on the surface of the tile.

    It’s probably similar but you can buy it at most tile shops. It’s specifically for sealing tiles.

    I was thinking something like this.

    Personally, I wouldn’t be drilling holes or putting anything visible on it, it’ll look worse if anything.

    Is it a tiny circular tile stuck down on a concrete floor and then grouted in? If it’s a recent install, can you source a new circular tile and matching grout? Remove it and replace, then re-grout?

    If not and assuming it’s on a suitable floor, and being a wet-room it should be, I’d be inclined to just leave it as is.

    Does it actually need sealed? Are these tiles not stuck onto a waterproof backing and come as a sheet?

    Short term (or even long term)


    • Dry off with hairdryer - enough to drive out any moisture from crack and below
    • Clean with Acetone
    • seal with superglue.


    Monitor it.

    as it’s a wet room floor I’d assume its tanked underneath and yes I’d say you are right on the tiles I’d imagine they come on a sheet (be a bugger to lay otherwise!)

    on that basis should be ok?

    It'll be fine. It looks like it's a sheet of separate circular tiles that are grouted once laid. As the adhesive that bonds the tile to the floor is essentially the same material that is used to grout in between the tiles you won't have any issues.

    Alternatively fill it with grey silicone caulk and forget about it

    Jeeez! anyone know how to fix cracked ribs?.............

    Not sure how you get silicon mastic into a crack - but feel free to elaborate.

    I suggested a 10minute solution.

    If you have movement in your wet room floor it could get worse.
