It's no secret that I LOVE using chalkboard paint whenever I can. So, a few months ago I wondered if you could add calcium or un-sanded grout to something like clear polyacrylic sealer and use it over regular paint to create a chalkboard. Well, it only took me several months to get back to that idea.
I started with what I already had - some Polycrylic and powdered calcium
The "guinea pig" for this project was a tray I bought at Goodwill and sprayed with some leftover Rustoleum Oil Rubbed Bronze paint. Still playing around with the ratios - I started with the same ratio as if I were using regular paint but it was way too thin. I kept adding calcium powder to thicken it up. So far, I'm pleased with the project. I'll share the final ratio soon - It's looking like 1 part calcium powder to 3 parts poly is best.
(And LOL - I don't mean to try to get all scientific here)

I'm excited to see what ratio you come up with. Thanks for being a scientist! :)
