Advice needed

[John Benton]

i recently put right a job that had been set on chipboard grout had failed after 10 days! tiles had failed soon after! i discovered the daft builder that thought he could tile, had the savvy to install ditra mat although he failed to bond it to the chipboard. thats a lie he had put 6 staples to hold it in place and maybe 20 blobs of gripfill. do it properly or dont touch it!

My thoughts were exactly that when I looked at the job

If you can't remove it, why not screw the chipboard to death then overlay with marmox. I wouldn't tile on that as it is.

Problem is Stewart the kitchen is installed on top of this insulated chipboard and its approx. 50mm thick

You can still cut that out.... And as I've said, I've done it in the past. You have a floating floor, which I personally will not tile on and always remove.

The only other option I can think of is Weber reccomend their addy and fixing guidelines specifically for floating floors. What kind of backup you would get when it fails, remains to be seen. I love Weber addy, but I still wouldn't use their method on a floating floor!

The chipboard will swell and bow with any moisture at all even under the kitchen (bloody builders) and i think chipboard is not recommended direct fixed to concrete ,for your own sake rip it out or walk

Hi Jay, The chipboard already has the insulation fixed to the back of it, so the board does not come into direct contact with the concrete. There is deflection in the floor as the sheets are only fixed at the corners i.e. 4 screws, but from the answers given by the guys already, it looks like it's a non-starter to be fixing to this substrate.

i didn't see it was insulated chipboard john, too much movement in that floor to tile on. if the customer doesn't want to rip it up then it's only good to lay lino or a wood floor on

Okay dont walk RUN

Spoken to him today and let him know the problems with the existing floor, told him I would only be prepared to do the job if the floor came up and was prepped correctly, and he said he wasn't prepared to remove it. The conversation ended so I can assume he is going to go ahead with someone who will tile over it!!!:mad2:
