I have a job to remove the paint from a slate fire place.

The slate is soft an can easily be scratched on the underside with a scrapper. The paint is flaking in places and well bonded in others.

Any ideas how to achieve this without eroding the slate as the owner wants a natural finish?

thanks

I'm thinking a chemical stripper. Softest grit is walnut shell at 2-3 moh, from what I've read slate is around 5.5 moh. This doesn't mean you can't hurt it with walnut shell.

Blasting will etch it

My brother in law is a high end Masson
We tried a lot of different type of stone with different media's (all types) they all left profiles on the slate and the man made slate is even worse

On the other end of things
Man mad slate that made to look natural
Was Being cut for a hearth and the owner didn't want a cut edge

We took some heavy tin cut jagged edges
Then blasted the edge with a template in different areas to make it layered
Fine glass only took a fast flash over to get a result

Any Idea what type of paint?
I would agree with the chemical. If you are lucky and it is a latex I think a citrus stripper will work, if acrylic than open the windows and set up some fans to get the order out for the stripper to remove it, and be careful the fumes will get you good.
