Tiles on wooden floor: moving and grout cracking - TilersForums.com

[aqua blue]

I see it like this....

Apart from doing the job right.
Floor tiles are heavy.
Checking the condition and strenght of the joists has a safety issue too.

Yes your right the more weight you put on the floor the more movement you are likley to create. Agree with the lads 6mm is not suitable for tiling onto.

As everybody above has said (especially Diamondtiling ). All the blame is on the builder, he has no idea what he is doing when it comes to tiling. The joists should have been secured before laying min 15mm ply. Get your money back and If you send Dave a private message Im sure he will give you the details of one of the experts from your area who can put the job right.
P.S
Spread the word, dont listen to builders who say "Yeah, I can do your tiling" :smilewinkgrin:

Sorry about your floor, but as above 6mm is not the way to prep a timber floor. Hope you get it sorted Good luck.

Thankyou all for you huge response and advice. A tiler he certainly isn't loads of his cuts have chipped edged and his mitred corners for the trim are rubbish...... but this really faded into insignificance 10 months ago when the job was done due to the flooring issues.

The tiles on the floor were flat initially, the slump of some on their beds has happened over the last 10 months since they were laid.

He is coming back to take the floor up but pretty much intended to relay doing the same! So your advice (apart from telling him to get lost and taking to court) is to take the floor up and lay 15mm ply over the floorboards before relaying........ or as some say remove floorboards and put 18mm followed by 6mm?

Seems mad me telling this "expert" what to do!!

Cheers

Just add lots of extra noggins before fixing the ply, you cant have too many. Prime the underside and edges of the ply before fitting.

the 6mm needs to be hardiebacker type board,not plywood!

 

[diamondtiling]

Are you going to let this guy relay your floor?

Get your money back and invest in an expert who will give you a guarantee, there are plenty on here.

Sounds to me as if your Builder is trying to be a "Jack of all Trades". Tiling is a Skilled job as is every other trade.

There is a huge difference in saying you can do it and actually "Doing it Correctly" I thought I could hang wallpaper and paint reasonably competently IMHO until I saw a time served painter & decorator doing it. Then I realised I was OK and passable but will never be any where near his standard. There are too many builders out there who believe they can do it all and it is just not possible to be an expert and specialist in all fields.

6mm ply should never be used . 18mm ply would solve the problem
