Kitchen Floor

[bathroomboy]

Just been asked to retile kitchen floor for a customer of which I did the bathroom late last year, they asked me a while ago to do the tiling in the kitchen which they were refitting, but I couldn,t fit it in for them at the time, and besides that most of my work is plumbing and bathrooms. Called round this morning and the floor has been bodged at first it looks good,setting out etc, but he has only put 6m/m ply down on wood floor, now they are moving after only 3 days.
I said can you not get him back to rectify it but he has offered only to rectify only the loose tiles, the customer has lost all confidence in him and wants me to start again from scratch and will wait till I can fit it in.
I asked did he prime the ply which should have been 12m/m not 6m/m they said no and not many screws were put down either, they have seen my work in the bathroom and suspected this was not right.
Also I don't know what addy and grout has been used but I suspect it's not flexible.

Should be 15mm actually or 18mm if you need to add strength to the floor. If sub flooris ok then 6mm tile backer boards.

Noticed lots of people mentioning 12mm ply recently :mad2:

 

[david campbell]

you can probably get away with 12mm in small rooms such as on-suites but all warranty and guarentees will be null and void(due to not complying with BS),easier just using 6mm cement boards with little cost difference

Agreed, big NMP fan myself. As professionals 'getting away with it' shouldn't really be our way of thinking.

12mm ply is ok for overboarding but not as a sole substrate:8:

Not following that

 

[White Room]

Overboarding onto existing floor, 18mm and above for fixing to joists with extra noggins

 

[macten]

So are we saying ignore BS of 15mm min WBP ply?
I have never used less than 22mm straight onto joists.

Doug is saying 12mm is ok for overboarding existing substate, eg sound t&g or chipboard. Providing there is no deflection, same as backer-board.
