Luckily I didn't try to grind it off or anything, at least not for long.
It was in my house in Poole where the previous owner had a thing about feature walls. The gloss paint prevented most other methods of removal and as I was trying not to damage the plaster I had to use those scrapers with an edge like a saw blade. I have googled it to try and find one but can't. Basically it looks like a 5" wide ornery paint scraper, but the edge of the blade has points like a saw blade about 6mm wide and 6mm high. I don't think you can get them any more, better ones are now available! Anyway, I wore two of them down so the points weren't there any more. The wall was only normal, Edwardian room size so about 12 foot wide by ... higher than 2m80. Obvs the chimney breast didn't help. So I chipped it all off mm by mm. I of course tried stripping the paint off, scoring the paint, getting water into it, etc, but nothing seemed to work very well. The room was a right mess by the time I had finished. I think it was the worst DIY job I have ever done. Took weeks. And I gave up on it so often as it was so depressing.
If I had to do it again I'd bash the plaster off the walls together with the artex and paint and get a spread in to redo them.
People said "Why don't you plaster over it?" I doubted the plaster would stick well to the gloss paint.
Perhaps I should have burned it off!
