I am about to start roasting some coffee and I thought it would be useful to make a few containers to store the coffee in. I chose to use chalk board paint so that as I got new coffees, I could easily change the information about the coffee. Even though this specific application is on a glazed ceramic container used to hold coffee, this method should work for a range of containers used to store virtually anything.
Begin by taping off the area that you want to cover in the chalkboard paint
Sand the area that you plan to cover in paint with 120 grit sand paper. Note: if the sand paper is too coarse, the scratches will show through the paint. Conversely, if the sand paper is too fine, the paint will not adhere properly.
tape paper towel or some other form of paper or plastic to protect the rest of the container during spraying. Spray a light coat of your favorite chalk board spay paint over the exposed area. Make sure the entire surface is covered in paint. Allow approximately 20 minutes for the first coat to dry before applying a second coat (the paint should change from a glossy shine to a dull look). After the second coat, allow 24 hours before continuing on... okay, I gave it about an hour and it all worked out, but the instructions on the can recommend 24 hours.
I used Painters markers for the permanent writing and simple chalk for the erasable writing. so there you have it, chalk board labeling.
