We should know better - Shouldn't we

[London Stone Paving]

Cant quite believe it, i must have made dozens of posts on this website about the dangers of using chemicals on Indian limestone. Set my guys the task of giving the display a bit of a clean. They were struggling to remove some dirt from the grout gaps in the kota blue limestone when one of my helpful customers pulled up and saw them struggling, decided toget a tub of acid out of his van and give them a hand. Result is that the kota blue now looks like a blue sky complete with heavy cummulus cloud cover. Will post some shots tomorrow

There you go Mate, just market them as "Sky Blue", sorted. I've got about 10m2 lying around the yard, that we had to replace for a customer who's Brickie used Acid cleaner, to clean some mortar stains off a Patio we'd done. His Brickie, who was Bricking up a Doorway for him, made the mess while we were a way for the weekend, and then denied doing it when we came back on the Monday, actually said he'd been nowhere near it. He used our sand, our mixer, and ruined about 10m2 of new Paving, and then refused to sort it. So you can have that to add to yours and sell it.:p

Not a bad idea that Mick.

The cost of rectifying is very expensive. We supplied some black limestone to a customer up near Gerrards Cross and we got a call from the client a month later saying the paving had gone all bloomy. I went for a look. I had a suspicion that the builder had used some chemicals to clean it with, but the client insisted that was not the case. She was requesting that we pay for a full re-lay. Roger went down to take a look and pretty much concurred that some chemical had been used. It also looked like it had been sealed the day before a huge downpour which made matters worse. Roger could repair it but it involved stripping off the whole surface layer of the stone and re-sealing. In the end thats what the client did, but as i said not a cheap solution.

Steve,
As you know I did the strip before xmas, so should be resealing later this year when conditions are right, hopefully they won't test anymore products on the paving while we wait!!!!
The other one in Whitton is going ahead in May, the one where the builders have messed up doing the extension.

Steve,

You should be able to flaten out the acid marks with a Limestone restorer. You would need to re-seal the paving with a colour enhancer sealer to get the depth of colour back though.
