Hi there new poster here, wish i knew about this place before what happened below!
I've had a Bradstone smooth natural sandstone laid and everything was looking really good, as below before grouting/sealing
I've been away for a few days and the builder sealed the patio with 1 coat of Thompsons Patio & Block Paving seal
I asked him to consult Bradstone and see who they use but he said Thompsons was fine and says sandstone on the tin.
He said when he put the sealer on it was very hot and was drying as he was rolling and then about 4 hours later it started to rain heavily.
As you'll see below I have a blotchy looking patio with air bubbles all over, dark edges and what appears to be grit under the surface. I'm absolutely gutted.
He said another coat would sort it but i've refused this and want this sealer removing and done properly.
Obviously you guys are the experts, what do you reccomend to rectify this?.
Thanks in advance
Nick

It is the worst product in the world, not suitable for any natural stone IMO don't care what it says on the tin etc, at the moment getting around 5-6 calls a week where people have used this shite and now have dire looking paving, it can be got off, but expensive and tiresome I'm afraid.

What products, routines would you reccomend for removing it.
Thanks again

Normally we remove this stuff with a floor buffing machine and a solvent, but seeing as you only have one coat applied, Lithofin's Wax Off, use it neat allow to dwell for around 20-30 mins, then gently pressure wash off, if you have good water pressure at your outside tap you could use this instead of the pressure washer, you might need to apply the wax-off twice just depends how the Thompsons crap sticks to the surface really, when the Wax Off is on the surface you could agitate with a stiff bristled brush to aid the removal process a stiff nylon brush is fine, just nothing that will mark or scratch the paving. Just follow the instructions on the Lithofin product, it is solvent based so watch your run off, as in flower beds etc. The other way is the use heat, as in a hot pressure washer around 150 degrees, what ever route you go, tiresome process unfortunately sorry it isn't the easy answer you might have been hoping for, but the sooner people stop using the rubbish the better.

Thank you ever so much for the replies, my friend has a hot pressure washer but its only 90 degrees so I've ordered the Lithofins Wax Off and a nylon brush and will use my cold pressure washer and will report back on how it goes.
Thanks again

The 90 degrees would be better then the cold machine, so if you can get access to it, I'd use it along with the Wax Off.

Only 5 or 6, Roger? I can get 10 times that some weeks!
That's why I call it The Patio Ruiner.
To be fair to the non-existent Thompsons, though, I reckon maybe as much as 75% of poor applications are down to what my tech friends call 'Client Side Error' - inappropriate or incorrect application. That stil leaves at least 25% that cannot be explained by incompetence and must be down to problems with the product and/or the substrate

It's just a terrible product for natural stone IMO Tony, noting more then a glorified glue. My 5-6 calls are constant week in week out in the summer months, sometimes homeowners mistakes but more then 50% is the guy/company that laid the paving who highly recommends the shite??? wonder why that is…..
