Porcelain tiled kitchen floor - cracking after 2 days - TilersForums.com

[Lisa123]

Hi all,

Just after a bit of advice please. I had my kitchen floor tiled last week (porcelain tiles).
I think there is movement and cracking/crumbling grout in some of the tiles. I supplied the tiles and the grout. The tiler supplied everything else including the adhesive. I think he’s used the incorrect adhesive but I just want your opinions and advice on what to do. He’s coming back to look tomorrow (and has already suggested in a text that it sounds like it hasn’t
bonded right).

He used mapei fast set adhesive (I know as I cleared the rubbish once done). I looked at the bag and it says for ceramic tiles. Mine are porcelain. Is this the likely issue with my movement and cracking/crumbling grout? Does the whole tiling job need re-doing? Should the tiler fix the issues at no extra cost to me? Is it a big job?

Hi.
What substrate is your floor. ?

Wood I think. The tiler said he was going to ply board and screw the floor to strengthen it.

He removed the vinyl and also the laminate under that. It was then down to what looked like a boarded floor.

Can you get the name of the adhesive please

Oh dear , wrong adhesive used. Needs to be min s1 flexible.. also is the ply he used min thickness stated in bs5385.

:-( thanks for confirming my suspicions. I’ll
ask about the ply tomorrow when he comes to look.

Does the whole thing need re-doing or could he get away with re-doing the area that I seem to be having problems with? (I think I know the answer, I just don’t want to hear it).

 

[Dave]

Imho. It needs to come up and re-done. Let us know the outcome

Does this person advertise as a professional tiler? or are they an oddjob/handy person? It is odd that they don't know what materials to use.

A tiling and plastering company apparently…

Did he check the existing floor for movement before over boarding? Loose floorboards won't be strengthened with plywood. Which is now not widely accepted as a suitable substrate to receive tiles. He should have fixed a cement board to overlay the existing solidly-fixed flooring (presuming it's wooden). Then used an S1 or S2 flexible tile adhesive.

I hope so but its not sounding likely is it :-( Definitely no cement board was used. He came the other day to re-lay a couple and did use the correct adhesive after
i pointed out he had used a C1F previously (but i’m still having issues with others so will be calling him back). I’m a little worried he may have used the dot and dab technique - I took a pic when he went out for lunch - attached. I’m no expert by any means but there looks to be a big gap to me?

Its not all of it i’m having issues with at the moment (its one section - which I feel was rushed as it was the last bit and he was here until around 7pm as he had another job the next day. ).

Just all a bit of a disaster really. Wondering if I cut my loses and see if I can get someone to fix it (although I don’t have a clue where to start with that).

What’s the PVA there for ?

I was hoping somebody might be able to tell me? :-( They seemed to remove the tile(s), put some PVA on and then go get some tile adhesive and re-laid a couple.

Pva is a no no , this so called trader isn’t a tiler and needs to be stopped. The whole job is a bodge.
