For many years I had a glass shower panel in my dining room that I used to keep a household calendar on.
This week, I sacrificed the whole wall to chalkboard paint. I wanted the freedom to change it and to really focus on one week at a time. With our schedule, the whole month was just lost in a sea of appointments. The thing about chalkboard paint is that if you really want it to be functional and erase well, you have to put on lots of smooth coats.
You can see how one coat won’t even cover the previous paint at all.
A few coats later you are in business.
One of the secrets to getting your paint to erase well is to spread chalk dust all over the board, wipe off and then start writing. Seems to be working great. I like its impermanence and the chance to change it as inspiration strikes me.
