Tiling

Can I Re-group only part of the floor?

Anonymous user 28/02/2024 - 3.14 PM

Hi Everyone, I have a new kitchen where the floor tiles go all the way under the kitchen units to the walls. The floor grout was supposed to be pink but when I lifted the floor protection, I found that it looks very dark and patchy even though it is completely dry. Unfortunately, the builder has now run away and not picking up my calls, so I was wondering if anyone here can give me advice as to how this can be fixed. If I need to re-grout - can I get away with only re-grouting the visible floor, or will I have to re-gout under the kitchen units too? I read that new grout doesn't stick to old, but I've seen patchwork done in a shower before that was fine. I was also wondering how deep to go with the grout removal when re-grouting. The tile is laid on an anti-cracking mat on moisture proof chipboard. Would removing all the grout damage the floor? Please kindly advise! Many thanks, Vincent

Hi Vincent Sorry to hear you had a bad job done! To re-grout your tiles, its best practice to remove as much of the old grout as you can. Just search on google for 'grout removal' and you will find some nice tools. Something like this from B&Q: http://bit.ly/1AvqcZ6 If you grout over the existing grout, its likely that the grout will come off as it doesn't have much of a key and may only be a mm or so thick. Over time, it will just come off. You would not have to grout under the kitchen units, because no one can see the tiles there. If you can get access, it may be advisable just to grout an inch or two under the units, just behind the plinth, so that nothing can be seen. Good luck, Tiel

Hi Vincent, Not good, grouting properly is a fundamental part of tiling no question, take it all up and start again with a competent tiler is in my opinion the best option, but if your finance is limited then removing the old grout with a grout remover and grout remover tool might be your only way forward, take your time and work carefully in sections. All the best, Peter
