An interesting string about stripping a wood ceiling with Walnut Shell Grit on contractortalk.com. The before and after pictures in the initial post are terrific examples of what can be accomplished with the right blast media.
- Used Extra Fine Walnut Shell Grit at 60 psi
- Screened media after blasting to re-use multiple times
- Stripped both lacquer and stain
- Minimal etching – sanded areas where grain was raised
