Tiles bowing after fitment

[square sticking]

Can't be at £70m2
I've just had 45m2 of 1500x750 delivered from Italy for half of that .
I did get them at cost mind , but even at full price the ain't much dearer

It was defo £600 and something, £680 or something like that but it did include grout and adhesive etc, I know the cost isn't always a guide to quality but I don't think they are poor tiles

are you skimming the back of the tiles?

Yes, about 1.5 mm

 

[Joseph Kover]

Yes, about 1.5 mm

I always do 3-4mm skim with throwel. It gives more leverage plus it's better connect to the Adhesive on the wall. 1mm skim not enough on bad walls
Check back my previous post I added more comment

Go on mark
If I'm honest, you do seem a bit ocd Pete , you have got to be a engineer ?
I'm all for a good job, but you are talking MMs (not the chocolate treat, the measurement )
Which in a man made product like a tile it is well wihin BS
Personally , owt 600mm or over is and can bend slightly , it even mentions it on some boxes , even lash clips won't help matters .
i doubt any tiler would stay on the job if you came in with your 12" ruler and pointed out a 1mm gap , big lippege , yes it's the tilers fault , slight, and I mean slight bowing, it's usually product error
I'm not having a go Pete, we are all entitled to our opinion mate ,but it does have a ring of a bit of OCD

Don't get me wrong, I am not going to start ripping them off, I don't do this as a job and I am taking my time trying to get it looking good and have found using a straight edge handy as a guide to getting the tiles flush. I need the extra help because I am not very skilled at the job (if at all !). It just puzzled me why they were pulling in and wondered if I was doing something wrong that one of you could spot or he maybe had before. It is only a mm or so and not a big deal just a bit strange.
Cheers Pete

1.5mm skim on the tiles are porous dries instantly.(you see at grouting it's dries instantly) On the wall you started you can't change for different skimming but you can do on new wall and see if it works. You get more adhesive needs for sure just make sure you calculate extra
3-4 mm skim on the tiles is with the teethed side not with the flat just to make sure I do vertical on the wall and horizontal on the tiles usually.
One more thing
These tiles usually have a little lip on their edge at their back goes around while centre part is not

Thanks both,

I am going to try with some Rubi levelling clips as these are 4mm when not tensioned where as the lash ones are more like 6mm.
I guess when tensioned the lash ones perhaps go to 3mm at a push but they would have to be really pulled tight.
I will let you know how I get on, thanks again.

Ciao, Pete

How are you getting on with the Rubi straps Pete?
Bed you're loosing the will to live aren't you?

It's a bit of a mixed bag really, I do like the fact that they are slimmer but I am not so sure that they go as tight as the lash system, also for an amateur the lash system is nice and easy to undo and re-tension.
I gave them a soak and tried using both one cup and then two as you suggested and they did the job.
My next job is helping my Daughter with her homework, then I WILL be loosing the will to live !

As the adhesive cures it will shrink a little and this will pull the whole of the tile back towards the wall. At the edges of the tile there are the bases of the clips behind the tile and so the adhesive set bed thickness can't be less than the thickness of the clip base, whereas in the centre of the tiles the bed thickness can shrink back to less than the thickness of the clip bases and cause the bowing in the tiles.
Just a guess at a possible cause!

I see what you mean, maybe the slimmer Rubi clips will make a difference ? Hats off to you people who do this everyday.

Try without any lash clips and less adhesive as a test on a fresh bit of wall maybe?

I wangled a "sample" set of the TileEasy clips from our local Tile Giant. Tried them, went back an bought some more. The are much more robust than the genesis and rubi systems, but am still keen to try the Raimondi version. One downside I found with them was that they can push the tile away from the adjacent one. Not too much of an issue, but you need to keep your eye on it when you tighten them up.

One quick question, how long did you leave the adhesive to set before knocking the clips out?

Which ones are the tileasy clips? I had a quick Google but couldn't find them. I've got the LASH ones and I do fine the base a bit thick to get under the tile as it is curved.

You need to get a away from them god damn awful things!
Take some advice Magga, dig deeper in your pocket mate.
Get another system.
If budget is a concern, go here
You won't be disappointed.
Get the pliers too, or go to kwiksplit and get these Raimondi ones.

Budget isn't a concern as such, I just got an absolute shed load of them really cheap from B&Q when it was closing down! I've looked at some of the other systems, but not sure which one to go for to be honest.
