Sorry but I am a blonde female so not familiar with much tiling jargon. I'm guessing ufh refers to underfloor heating. No, I don't have that. the floor is concrete, was screed 5 yrs ago. Nice and flat, no divots or bumps and sealed with PVA four days before tiling began.
Just removed laminate flooring to have ceramic tiles but beginning to regret it as the workmen are making a right hash of it. After being advised that there should be an expansion gap I disputed their claims that there doesn't need to be a gap between floor tile and upstand. I was kindly given some info and printed a document which described the
BS 5385 recommendations for internal corners. That seemed to frighten the hell out of them and they've decided to rip off all the upstands off and redo with 4mm gaps tomorrow. Since they've left, I've checked the floor thoroughly and apart from some gaps on floor tiles being 6mm with some being 3mm, (yes, they supposedly used spacers) I've found chipped tiles and they did not clean out the adhesive between tiles. I've been told that grouting over such will result in the grout cracking. Is this true and if so will they need to gouge out the adhesive beofre grouting?
In addition some tiles are less than 2mm from the wall. Is this acceptable?
I really appreciate any advice.
