Dark patches appearing on limestone floor tiles after laying and sealing - TilersForums.com

[jburnett]

Hi all,

I'm really hoping you can give me some advice.

I've just had my kitchen floor tiled in light grey Jura limestone tiles.
The tiler fixed them on top of the existing ceramic tiles with Setaflex grey adhesive using the "spot" technique rather than a solid bed. Some areas where there were no ceramic tiles were levelled using a self levelling compound. In some area the tiler used white adhesive from BAL because he'd run out of grey Setaflex.

All the tiles were left for between 48 and 72 hours before a first coat of sealer called Dry Treat Damp Proof was applied.

Within a couple of hours dark patches started to appear on the surface of all the tiles, with the exception of those laid on the self-levelling compound and on the white BAL adhesive.

That was about a week ago and the patches haven't changed appearance at all since.

Are these patches ever going to fade?
Is the limestone stained forever?
Should the tiler have used white adhesive all over?

Any advice really, really welcome as neither the tiler or the supplier of the stone/adhesive seems willing to take responsibility. I'm stuck in the middle and have had to cancel the kitchen fitter in case the whole floor needs to be replaced.

Thanks all. Some photos attached.

Your tiler should not have used the dab method,not a good method for fixing and white should have been used for the Limestone..

How thick were the dabs of adhesive.

Hi and welcome..

Those marks are wetting from Spot fixing the tiles.. Totally wrong installation method... they might fade but cannot guarantee that..

The tiles should have been back skimmed to give even wetting/shading tot he tiles and solid bed fixed and not spot fixed like that.

time to give your tiler a call.. State to him that he has not fixed to BS 5385 standards.

Not really sure how thick they were but I guess between 6 and 12mm.

Errr,, The tiler is fully responsible here. He is the one who did this..

Firstly the tiler should not have used grey adhesive, it should have been white rapid flex. Spot fixing is not a recognised technique for tile fixing, it should have bee solid bed. I doubt very much the spots will disappear and you will probably start to have problems with the fixing of the tiles as they will start to fail. I really hate to say it, but get in touch with tiler as a re-fit is in order in my opinion.....

This is really bad.wrong addy, wrong fixing,all down to the tiler.remove and start again,inc ceramics if their are not 100% solid all over.
