For some time, I’ve been intrigued by the idea of painted on whiteboard surfaces. I have a shop/office in a commercial loft in Philadelphia with plain white drywall partitions. When I was in Home Depot I saw this Rust-Oleum paint. It’s about $20. I thought I’d give it a try.
My dad was at the shop and did the job for me. Results below. In sum, it’s pretty good stuff. Make sure the wall is nice and smooth. There were a few nubs on my wall, and these get knocked off with use, and then the marker adheres to those knocked-off spots. We applied three coats to create about 30 square feet of surface. We used about 2/3 of the paint. The coverage information on the can implies you can create 70 square feet. I think you can do about half of that realistically. It’s a two-part epoxy paint. We used a postal scale to weigh proportions.
