Please Help

Hello Guys, please can you give me some advice. We have just had our bathroom tiled today by the council, it was part of the housing modernisations.
The bathroom has been tiled over some very recently plastered walls they were plastered (approx 4 weeks) ago.

Question
Should the newly plastered walls have been coated with some sort of PVA bonding before the tiles were put on??
Also the tiler tiled over some 1/2" thick ply board that was boxing all the pipes in, no PVA bonding was use on either the newly plastered walls or the boarding.
Question
Should the ply board have been coated with some sort of PVA bonding before the tiles were put on??

Up to now 6 tiles have fell off the plywood and 3 off the main wall, I know the tiler told me he was running short of tiling adhesive as he told me 15 minutes before he finished the job today. He came downstairs and told me he had finished the job and that he managed to scrape just enough adhesive out of the bucket to finish the job, I said to my Husband I bet there's not much adhesive on those last batch of tiles he's put on. I was right the 5 tiles that fell off the main wall were the last ones he put on, I checked the back off them and the wall for the supposed adhesive you would be lucky if there was enough on the back of one tile to cover half a slice of toast never mind a 12 inch tile.

I'm well peed off

Thank You

First off he should use an acrylic primer not PVA.

However, if the tile is small enough to use tubbed adhesive, then priming is often not required. You mention 12" tiles, sounds rather large did you mean 6" tiles? If so, then no priming, no dot and dabbing just good old fashioned fixing is required. Tell the fixer to use a 6mm notched trowel and all will be well.

 

[Daz]

Just re-read your post.

Has he grouted yet?
If not, then he will need to re-fix before grouting. Tubbed addy will need 24hrs to set so he must use a cement based rapid set if he is to repair and grout in the same day.

Sorry I have just measured the tiles and they are 10x10
The jobs finished now, he did use a trowel. There are a lot of tiles that are loose now I have looked and more coming away from the ply board.

 

[White Room]

There going to need redoing IMO

 

[annette]

No he has not grouted yet

 

[annette]

The adhesive he used was Mapegrip d1

 

[White Room]

The tiles should have been fixed with a powdered adhesive and primed prior to fixing for that size tile, Not with pva I might add

 

[Daz]

No he has not grouted yet

Give him hell when he returns to grout.

You need to know what adhesive he used?
What trowel he used?
Did he prime the substrate first?

Hit him with a curved ball - Did he tank the bath and shower area? (we all know he didn't)

Then ask him why the tiles have come away? And what is he going to do to ensure that they don't come away again?

Did he "comb" the adhesive or dot and dab?

Just remember, that if he uses ready mixed adhesive, he can't grout for at least 24 hours.

I really need to know the facts, with the tiles been 10x10 should the new plastered walls and wood have been Primed?? I need to be armed with this information when we visit the council on Monday, we actually paid £300 for 6 meters of tiling, they were only going to do half the bathroom so we had to pay the rest, guess which bit of the bathrooms tiles are put on the worse, you guessed right the walls we had to pay extra for. Thank You all for helping me.

Believe me your tiles will be coming off in a very short time

 

[Daz]

Primer no, but the adhesive is only one step up from DIY stuff, which is c**p and not suitable for a bathroom.

Sounds like he hasn't applied the adhesive correctly and / or bedded the tiles properly. Probably covered too large an area with adhesive so it has skinned before he has got round to applying the tiles.

Just a thought, but sounds like a poor fixing job to me.

BTW, 6m2 should cost you a maximum of £150. If you're near me, I'll come and do it properly??

 

[annette]

You need to know what adhesive he used? MAPEGRIP D1
What trowel he used? DONT KNOW A ONE WITH GROVES IN IT
Did he prime the substrate first? WHAT DO YOU MEAN

Hit him with a curved ball - Did he tank the bath and shower area? (we all know he didn't) NO HE DIDN'T

Then ask him why the tiles have come away? And what is he going to do to ensure that they don't come away again?

Did he "comb" the adhesive or dot and dab? HE COMBED THE BACK OF SOME TILES AND IN SOME PLACES HE JUST PUT A BIG AREA OF ADHESIVE ON THE WALL AND STARTED PUTTING THE TILES ON

Just remember, that if he uses ready mixed adhesive, he can't grout for at least 24 hours

Also look at the council spec, It may be they are responsible for the materials

£300 was for the tiles as well as the work, I know it would have been a fair price if the work was done properly :dizzy2:

 

[annette]

The tiler was a sub contractor working for the council.

 

[White Room]

The sub contractor surly must be responsible for materials, He priced it and should advised the council what was required

The price doesn't sound too bad then. It sounds like poor quality fixing.
If the tiles are coming off, then it seems perfectly reasonable to question the quality and ability of the fixer.

I agree with you, I hope they will redo the bathroom properly and next time use some primer under the tiles.

He was only a young lad who did the work, he did say he had never done a full bathroom before and it took him 4 days to do it, the size of the room is about at a guess 14 meters or less

 

[White Room]

Stand your ground and please come back to the forum if you need any more advise

 

[Daz]

I've got to agree with Whitebeam, argue your case.
I'm not sure that you had a competent tiler in the first place, though.

Good luck..

I have just taken some pictures and will put them up here in a while

Oh my, cant believe he tried to tile over the rad brackets, surely you should get a council rep round to view this work and they should get their sub con shot or a similar fate for this appalling work.:smash:
