I'm not familiar with this process. What does it do to the stone?
Good question, I would like to know as well.Quote:

You can see smal particles being blown off!
So it's a spalling process as is done to concrete.
It's also done to the edges of flagstones to remove the saw marks & make the edge look "natural". Wet the stone, let it soak in & boil the water off with a blue wrench. Spits hot stone flakes all over the place.
Being from Canada, I figured you would have seen this around. It texturizes the stone so it is not as slippery in the winter.Quote:
