Large format tiles getting them flush

[GaryS]

Hi guys if you have been reading my other posts you will know that Ive been doing a job with 600 * 600 quartz tiles I had to tile on a floor that was anything but flat so it made the job fun, in the end i used packers under the tiles to try hold them in place where the addy was thicker till it set as the weight of these tiles moved them after they were on the floor, my question is this is there an easier way to get these tiles to stay perfectly flush or is it just a case of what i have already done.

Ideally you should have levelled the floor first with slc, especially with large format tiles as it makes the job so much easier.....

there was more than 20mm of difference over this area so slc would be costly these big tiles seem to move about a lot after being fitted packers seemed to be the only way to get them to stay put while the addy cured

Packers?
How thick was your mix? If they are slumping under their own weight sounds like it could be too loose a mix. How much are you have to bed them up?

there is always lash clips?

20mm! Is the adhesive ok for that thickness?

So's putting all that adhesive down as well.

in some areas the addy is only 4mm thick but in others it goes to 20mm the floor was a nightmare to keep level it was ptb addy so the depth ok just getting the damn tiles to stay where they were fitted was fun it was those black shiny 12mm thick quartz tiles over a 55m2 area but subfloor wasnt great to say the least. never heard of lash clips ?

I knew there had to be an easier way than the time consuming method i used thanks again for the great advice on here

building up tiles is very time consuming and frustrating, away better to get the floor prepared fist.

I would have slc'ed the floor, got a good even thickness of addy and flush tiles.....it's all in the preparation.

Either way you pay for extra adhesive or SLC....I know which I prefer....sounds like a case of cutting corners to me and ending up paying the price !

As above with the slc. What you have to be aware of with laying large format tile(or any floor tile really) is if you get your subfloor right the tiles almost fall into place and very quickly too. If your subfloor is up and down you'll wrestle from start to finish and the job will take a lot longer.

prior preperation prevents poor performance.
The SLC would have cost about the same as the extra addy you have needed, but the extra time (days) you spent fixing the tiles must have cost either you or the client.

Wrestle was the operative word on this one the finish is nice and flat now but oh boy was it fun to get there, as for slc is there any particular product that would be reconmmended for that kind of thickness, I would normally have used ardtex screeds but wouldnt normaly build up that kind of depth on them.
