Hi Paula. I’ve been reading this thread as I also have wet grouting patches on my former tray tiles after using the shower for the first time. I also have impey membrane. Only the flooring is tanked just like yourself. This is also on timber floor. Mine is actually not a full wetroom as the tanking only goes up a few tiles past the screen. Fingers crossed on that one. 😬

I havent used the shower and you can clearly see one patch that stays wet even after 24 hours. It feels wet to touch and I can see the wetness.

I can also see about 5 pinholes in the grout in the wet patch area which I suspect is the issue. This seems like a poor mix.

There are some other dark patches but they are cloudy and feel dry to touch and when I run my fingernail across it it kind of comes off and lightens. It’s surface only. Builders think that is soap residue from the mastic guy. It sounds plausible.

The builders are now raking the wet grout lines with pinholes out and will regrout. Anyway hopefully that resolves it.

My question to you is. Am I correct you regret the epoxy? The evaporation capacity of cement grout is probably a good thing all things considered and it’s easy regrout?

How did things end up?

Thank you
