I used a premix Karcher patio cleaner solution so I'm not sure if that had anything in it. Do you think it can defiantly be fixed or is it buggered?? Do you think Thomsons will accept any liability.
Okay, surface may have been dry but still been some moisture in the paving?
I don't know what is in the Karcher cleaner sorry.
Yes it is fixable won't be cheap though, would Thompson accept any liability? I don't know, as from the photos you have shown, does look like a bit of moisture/dampness hasn't helped the issue and that could be their argument?
Many thanks for your time Roger. I have sent a email to Thomsons about this but I won't hold my breath!! I can't believe that they sell this product knowing the impact that it could potentially have.
a quick google tells me the karcher stuff is just a detergent
so looks like you have sealed in moisture
as roger says it is gonna be a PITA to put right

Fot Thompson's patio crap, I use Miracle coatings remover, used to use Aqua-Mix but they have pretty much stopped selling in the UK, the solvent remover is used with a low speed rotary cleaner medium brush, the one thing with the Thompson's is it goes like a glue once the stripper starts to go like a glue, so on a patio of say 40 sq meters I end up having to throw away a brush as they are f**ked so £80.00 odd out the window. BTW any decent sealer or coatings remover will remove the rubbish sealer.After removal, we re-clean & re-hone the surface before re-sealing etc.

Which ones are acid based?
The thing is, if you have a Limestone paving that has been ruined by either the home-owner using the wrong products or contractors doing the same, we have to re-etch the surface using certain acid's to get the paving to balance out again prior to sealing but not the old favourite "Brick Acid" which is the one that will screw your Limestone up. Limestone is a Calcium based stone if I'm correct.
Cheers for the link, I think you put it up before but I forgot to bookmark it, yes they do look like they do so decent coating removers most seem to have DCM in them which is a good chemical but nasty to use so great care is needed when using.

You must be reading the wrong MSDS it's Mira Strip from Miracle you would use to remove sealers/coatings it's solvent based not acidic they do a water based one too. I have used both.

I have now had the opportunity to discuss your case with a senior team member.
My colleague has advised that these white patches have been caused by problems with the jointing compound used.
My colleague's advice to you is to scrub the affected areas in a circular motion with white spirit.
In addition to this I will send you some replacement High Performance Patio and Block Paving Seal to repeat the same process on the affected areas.
If you are happy to accept this offer in resolution of your complaint, please let me know by return.
Also I would appreciate if you could supply me with a contact telephone number for our carrier.
I look forward to hearing from you.
Kind Regards
Helen.

Ask them to come down and do this for you, White spirt and scrubbing with what? a brillo pad FFS
Good luck with this mate, all this proves to me is their stuff is no more then a cheap acrylic sealer which is absolutely useless for natural stone (so a surface sealer) and all the white sprit will do is just possibly release the moisture and drop their crap sealer back down again once it evaporates same as you do with PIC sealers that get moisture under the sealer.
But as I said get their "Experts" to come down and do this and then re-seal, and getting a finish say as in the photos I put up after removing this shite. Don't mean this to sound big-headed but I've been doing this a long time and their idea of resolving this sounds bollocks.
