I see waxed plaster walls in interior design magazines quite a lot, and I've seen them at some very nice modern hotels as well. They look like really smooth granite almost. I'm thinking of trying this in a guest bathroom we're building at home, on walls that aren't in direct contact with water.
If anyone's done this, I'd love to hear about the challenges and any tips. And if there's a book that covers the subject, I'd appreciate any pointers.
Thanks!
