Limestone tiles water marks days after being laid

[Leigh]

Hi I’m looking for some advice regarding some limestone floor tiles we are laying. They are coming up with water marks that don’t seem to be drying after around 5 days. They were laid on a bed of white adhesive which is fully across the tiles not just the corners. The floor was coated with pva.

Any advice on why this has happened and if the water marks will dry eventually would be great

Um, not quite sure where to start with this one. PVA is a huge no no. What adhesive was used and onto what substrate?

They haven’t been sealed yet, the shop advised to seal once after they’ve been laid then again after grouting. Is the pva the cause?

White flex fibre from Topps tiles, the salesman said this was the one to use. They are laid onto levelling compound as the floor was uneven. Is the pva the problem?

I had a thread up a while ago about limestone that had been blobbed down on a window cill by a builder and @Paul C. came up with this..

What makes you think it's water.
Is your adhesive slow or fast set .
Is it honed and filled limestone and have you been backfilling the tiles .

 

[CJ]

If it’s slow set, it can take an age to totally dry. Also, As mentioned, PVA is a no no......

It looks like water, what else could it be?
Slow set
I’m not sure on the last question so possibly not

This says not to use on limestone on the product description, should I still use it?

I now have the proper primer for the floor so there will be no more ppv

It’s just a question on what to do with the first half of the tiles. Should I take them up and start again or will they dry out eventually

Forget the last question , i. wasnt thinking straight and started thinking travertine

I’d leave it for a few days, don’t grout, get some ventilation going.

Also, how long after self levelling was it tiled?

have you not used a decoupling mat?

2 days after. It’s been down around 5 days so far with no improvement

Do you know if the product actually worked to remove the dark patches for the tiles on the window sill as the screen shot only mentions he found the product

 

[Dumbo]

Tbh you could save a few quid by using grey adhesive , I wouldn't use white with those as any adhesive you get on top will show more than grey adhesive even after you've cleaned it of .

Hi the product that was referred to earlier in the post is called LTP cement grout and salt residue remover which is an acid replacement unlike LTP grout stain remover whic is an acid and cannot be used on acid sensitive stone, where as the cement grout and salt residue remover can as long as it's not polished stone.
If you need a sample call them and they will drop one in the post.

looked at photos and looked at joints i may be wrong but looks like they have been spot dabed with my guess a slow setting addy so moisture is leaching through the tiles try taking one up to prove me wrong

They are all covered fully, the adhesive was the one tops tiles sold me with the tiles
