Does chalkboard paint work on mirrors?

Yes, chalkboard paint can work on mirrors, but the results may vary. The paint can create a writable surface on the mirror, but it might not adhere as well as it does on other surfaces, potentially leading to peeling or chipping. It's recommended to clean the mirror thoroughly before application and to use a primer designed for glass if necessary. Additionally, keep in mind that the reflective quality of the mirror will be diminished once painted.
