Looking for advice on this one please.

I am a self builder. I have had a guy, whio says he is a tiler, lay 100 sq m of 600mm sq porcelain floor tiles over a concrete floor which has water based under floor heating in it. Due to the concrete floor not being perfectly level, he said that the tiles had to be laid had to be laid on pads. These only cover about 50% of the tile area underneath the tile. In addition he has used rapid set adhesive. There are huge voids underneath each tile. The have been filled using a flexibile grout.

Result: About 40% of the tiles are now loose. The grout is all flaking and dropping out. No doubt due to the tiles being put on pads and not having anything under the grout to keep it in.

Has this been laid correctly? Can tiles be laid on pads. Has the correct adhesive been used?

Do I have any comeback with the Tiler?

Advice please.

Can you explain what you mean by pads ?...please post photographs if you can so a full assessment can be made....Gaz

Has he fixed the tiles using 'blobs' of adhesive under each tile?

Rossi im afraid your tiler is another john wayne (cowboy) floor tiling should be a solid bed fix meaning 100% coverage or near enough if a floor is uneven then the tiler should have told you to level it, in some cases if the floor is slightly uneven you should still spread the adhesive onto the floor. Rapid set adhesive is a big no no for porcelain he should be using a flexible adhesive. as soon as these muppets get out of our trade the better.

i cant see your tiles sticking for long i can see it being re tiled soon

Yup, good old spot fixing.

Rossi, the good news is, the correct adhesive has been used.
The bad news is, the tiles have been laid incorrectly.

you need 100% coverage.

I thought he used flexi adhesive.
But reading it again, it was not. Just flexi grout.

So, sorry Rossi, there was no good news.

james rapid set adhesive has been used to lay porcelain not flexi how can this be the correct adhesive?

ive got a funny feeling that this tiler uses rapid set on everything including natural stone

Gaz you could always use PCI products but try not to spot em lol

Blimey that got confusing

Sorry about your floor the adhesive and the method of fixing are unsuitable. Can you give the name of the fixer as I think we should be naming and shaming these people
