I've rushed in and tiled my bathroom floor without thinking it through first.

Now, I reckon I am going to have problems having heard someone elses tale where they did the same.

It's a wooden floor. Most of it was 18mm exterior ply, but some the existing large chipboarding. I've used cement based adhesive and grout that I have mixed myself, but discovered I should have added a flexi agent to prevent it cracking with the floor movement.

The boards were all screwed down, but no doubt it won't be enough to prevent some flexing, so I am expecting the inevitable cracking of the grout to happen.

What's the best thing I can do? See if it cracks and then:

a) pull it up and redo correctly?
b) remove the grout and re-grout with flexi grout?
c) move house and leave it for someone else?

Can anyone advise the best way forward, beyond the advice of doing my research in future!!

sit tight and see if the grout cracks first ,which it probably will.My advice would be to ply over the whole floor area with 12mm ply and tile using a rapid setting flexi adhesive and a flexi grout.If unsure about anything tiling related,then ask on the forums first.

are you sure that your adhesive and grout were not flexible Tucker, if they weren't there's every chance your tiles will de-bond and/or crack. If it was my floor, I'd be taking them up and re-doing before anybody notices

Hi

No, having done the man thing of reading the instructions after the event, it seems to require some unibond flexi solution instead of water when mixing.

There's already a hairline crack along one joint, so I think I'll take them up (well except the two that I put in before the toilet - I'd rather live with those than remove and refit the toilet!).

I think the bit that gets walked on is where it's going to definately happen. Some of the smaller ones I cut around the far edge might be OK. Refitting the full ones with no cutting won't be quite so bad. I might be able to scrape the grout from the remaining and use flexi grout in those joints?

The question now is, will the tile lift with the adhesive (lots of spare tiles so I would prefer that) or will I be scraping it from the floor for ever?

Is any flexi adhesive better recommended, as I will need some more of that for take 2.
