Tiles bowing after fitment

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 :fearscream:
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:tearsofjoy: , big lippege , yes it's the tilers fault , slight, and I mean slight bowing, it's usually product error :flushed:
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 :yum:
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.
 
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.
 
Looking at the available ones, I think the wedge provides more pressure, so I suppose one with a flat base, and that uses wedges! Probably the Raimondi ones would be the best, as their stuff is generally pretty good. I suppose I just worry that because the base is flat, you could potentially pull it down too much?
 
Heard a few systems can move the tile when tightening. The caps on those can kinda twist the tile away, opening the joint. Thats why i wanna test the raimondi ones cuz you can push the wedge in the direction of the adjacent tile instead of away from it.
 
Yeah, the wedges do really hurt your hands though, but you can get pliers for the Raimondi ones, which is a huge plus imo. I also like the fact that the Raimondi ones come in 3mm thickness, which is what spacing I use most commonly.
 
It's the use of the pliers that prevents the wedges pushing the tile away.
If you want the best system in the uk market, then get the original Rubi levelling straps.
Pull down from the top, no sideways movement, and plenty of feedback through the pliers.
They've also dropped in price recently, because of all the competition no doubt!
 
Apparently very similar, but not tried them.
I do have a good friend who swears by them.

I swore AT them. Too easy to over tighten them. But then again, if i didn't put too much adhesive under that tile, prolly woulda been ok.

Anyway, who took the thread off topic?
 
I've tried 4 systems. The Australian ATR type, don't like them, too much time taken to construct them before use and they go in the corner of tiles so you can't see if the tiles are aligned perfectly, also not very strong, they break of premeturley far too often. I tried both the 2&3mm sizes and also the T type.
The Lash system I found to be too crude and bulky in comparison to similar type systems.
The Ramondi RLS I tried last week for the first time, couldn't wait to try them as so many members use them. They are very well made, good quality, but they do tend to move the adjoining tile and you constantly have to check that all is in line.
The system I've used the most is the Genesis, both versions. In my opinion this design of clamping tiles is much superior because there's no lateral pressure only vertical therefore no moving of adjoining tiles what so ever, a much more accurate way of working plus there's no tile depth limit restricting you and if your working with say a slate tile for example they can still work. My criticism of this system is that it's not quite as well made as the Ramondi system, the teeth on the pliers do wear out after a while and on the smaller top caps you will get small wastage when breaking them out the next day.
I've yet to try the Rubi system, but as it's the same technique as the Genesis system I'm sure it will be an excellent product, therefore for me it would come down to price and availability.
I'll post a pic of a floor I did using the RLS and the Genesis system together to see how the preformed in exactly the same conditions and tiles.
