I'm a chippy, I fit a lot of kitchens and some bathrooms, inevitably I have done quite a bit of tiling, which I have learnt from older tradesman I have worked with in my early years in the trade. I've never had a complaint about my tiling, I don't class myself as a tiler, I can accurately cut a tile, I can space them, I can get them level, I know you must get a bond with the adhesive, etc. I know that what you're tiling onto can often be the most problematic part of tiling and I'm certainly not an expert in that, which I'm very honest about.

A couple of years ago I was on a job doing general carpentry work, there was a tiler on the job doing the bathrooms, I was lined up to do the wood flooring down stairs, the homeowner/site runner came to us a few days before the flooring was due to get started and said he'd decided to have tiles instead of wood, fair enough, he also said he'd had a price from the tiler but he thought it was too much, he knew I had done tiling, he asked if me and my mate would do it on a day rate, we foolishly agreed, but because it was due to be laid on chipboard I told my customer I knew nothing about that and I doubted you would even be able to tile on chipboard and that he should tell the tile shop the situation and take their advice on it. He came back and said it's fine, we just need to use this particular primer which he got and applied to the floor, he also suggested we used lash clips, I said I've never heard of them but I'll give them a go, I laid a few tiles with a 12mm towel, because of the clips I decided a bigger trowel would be better so I went and bought a 20mm trowel, the evening of that first day the plumber came and connected up the piped underfloor heating, the plumber works on sites with this sort of thing going on all the time so I thought nothing of it (he knows best I thought) the next five days we spent tiling the heating was gradually being turned up (apparently that's what you have to do with new underfloor heating). I should also mention, it was January, freezing cold and the chipboard was brand-new freshly laid within days of tiling. We grouted and then our customer changed his mind on grout colour and put a different grout over the top of our grout himself one weekend. With in a couple of months I think, grout was coming out, some tiles were loose and some cracked. Something I should mention, my customer thought it was faulty adhesive and contacted mapei, who sent a rep, he lifted one tile and told him that the tiler should have applied adhesive to the back of the tile as well as the floor! I put my hands up, I have never heard of that and neither have any of the local tradesmen I have spoken to in my area.

What do u reckon is the most likely cause of the problems?

Many thanks!

I am sorry mate but you should stick to your trade and never get involved with tiling again.Hardieboard on top chipboard stick with adhesive and screw every 200-250 mm

A catalogue of errors really. No back buttering, chipboard should’ve been overboarded and UFH should’ve been left for a month before properly commissioning.

Unfortunately Stan you won’t get too much sympathy from the tilers on here!
They are a miserable bunch and can’t wait to stick the chisel in.
Now me, well I have to agree you did everything incorrect from tiling onto chipboard, not back buttering the tiles, no experience of levelling clips ....etc.
Now I’am not sure where you expect this to go but I’d blame the plumber for turning the heating on too soon and too high despite you telling them not to ( see where that’s going).
2 years ago the job so what does the customer want you to do?

Cheers for all replies, wasn't expecting much sympathy, I know how it works. Surprised by everyone saying back buttering is definite issue, but fair do's.

Where do I expect it to go?... well my customer obviously wants it sorting, I have insurance which I hope and pray would cover it, otherwise **** knows what I'm going to do. I'm just not happy about taking full blame, I said to my customer from the start I doubted you could tile chipboard and we would probably have to board it, he went off to tile giant and came back with a gritty primer they told him he could use on chipboard. I was very honest with my customer about my tiling knowledge and experience. My biggest fault was getting involved in the first place the way I see it.

I don't think back buttering would of saved it . Mapei don't want admit their adhesive isn't suitable for chip board . Alsoturning on heating whilst tiling is out of order . Basically a catalogue of errors . Admittedly you tiled in good faith at the direction of your client but you have a duty to find out for yourself

Yeah I wish I had now. Trouble is I was kind of friends with the guy, he was an old neighbour, so the arrangement was kind of relaxed. We're not really friends now. Reckon I should just put my hands up and hang for it?
