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

Cyrus

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 ?

Hi, personally I'd leave it be, the wet-room should be tanked under the tile to prevent water from penetrating and that crack can't spread as it's isolated to one small tile and surrounded with grout. If it opens up and becomes a void then I'd remove it and replace it with a spare, but I'd like to think that won't happen as it's so small.

Would epoxy resin be good to seal it?

Clean and dry the crack using a hairdryer. Get a shade of cheap nail varnish to match tile colour the apply a couple of coats to the crack. Make sure it's dry before you put 2nd coat on. TBH I'd just leave it but I'm lazy.

Yes, if you dry it well enough. The epoxy should wick in quite readily.

Varnish may wear off , epoxy wouldn't I'd go with that. Although it's like 10 euro for a small 2 part. You can reuse them though

Epoxy probably the man for the job or maybe a small tube of the gorilla waterproof caulk/sealant that's already mixed for a few quid

Epoxy is the best choice alright, I have a double stringe of it that is still great for small jobs after being opened a couple of years ago. I picked up a few packs of it in Lidl recently, I think it was priced about 3 euro.

I'd dry it really well (fan on it) and then see if super glue would wick into the crack?

Epoxy is like super glue on steroids, better off to use something that is specifically designed for the job.

Epoxy is thick thats a very small crack how much do you think you'll get into it? Theres a chance if its dry that super glue will wick all the way into the crack.

The other stuff I'd use - it really exists - is Captain Tolley's Creeping Crack Cure.

You normally use it when you know you have a leak on a boat or caravan. I found it brilliant to stop water getting into the boot of my Ford Focus (water gets in along tiny cracks between panels). It does need redoing occasionally but if you seal the bottle and only use it on hairline cracks or where you think there are leaks it lasts for ages. Again it wicks into the crack and seals it on the inside.

Epoxy can be blown into the crack with a hairdryer set to cool.

Masking tape up all around crack easily done.
