I have a large piece of slate chalkboard from an old schoolhouse. I want to hang it for my children to play with. However, it has a sharp chip on one side. The area is still pretty thick. Can I sand it down, and if so, what should I use?
I don't know of any way you could sand down a chalkboard but I was thinking maybe the next best thing would be to put a frame around the whole thing. It might cover up the sharp edge. I don't know how big the chip is but after you frame it and it still doesn't cover the chip maybe you could use some type of filler to fill in the hole, sand it and then you could paint it with chalkboard paint.
