Tiles bowing after fitment

[Old Mod]

The Rubi straps are what I'll use out of choice.
You barely need 2mm to insert them.
Make sure you soak them first, you'll get a lot more feedback Thro the pliers.
They are a nack, like all these things.
But if you find yourself snapping them, use two cups not one.
It'll help you find that spot before it snaps.

I never read some of the comments on the thread but you could be suffering from shrinkage as the addy may be deeper or shallower in the middle of the tile.
A lippage system would & will solve this kind of problem.

Could be suffering from OCD not shrinkage....

What is OCD ?
Does it stand for Ordinary Ceramic Distortion ?

Don't try and be clever, you know what I'm talking about.

What make of tiles are they - BCT?

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

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

 

[Italy]

for me, enough to eliminate clips, or increase adhesive thickness

Ah but these may be made in Greece and we all know how expensive Kefalonia is!
I'd need to see a receipt to believe a white biscuit ceramic was that price.
With you on the engineer and OCD.

Its ok john, the wife is paying

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!

Have you got an image straight after fitting when they are flash? Usually it's opposite, bended at centre by default

are you skimming the back of the tiles?
Can you see on the top it's bended just as I said earlier
Try put two tiles on their faces and check how it lines up, then compare to few other ones. I bet all has difference, if the tiles is very light weight, they suck the water out of adhesive and can do such effect. Another thing is you may need to adjust adhesive behind some corners and it bends the tiles as you apply pressure . Make sure you re using equal amount of adhesive
