Chalkboard paint can be used to create a writable and erasable surface on everything from walls and ceilings to collectibles and toys. Hardware stores often sell chalkboard paint, but depending on where you buy it, it can be expensive. Making your own chalkboard paint is relatively simple and only requires a few ingredients.
Chalkboard paint does not have to be black or green like traditional chalkboards. It can be put together in a variety of colors. Choose the color with which you would like to create chalkboard paint.
Decide beforehand how much paint you are going to need, as you do not want to mix up too much. This mixture will not store well, and if you make too much paint you may have to throw it away.
Mix two tbsp. of unsanded tile grout and six tsp. of water-based glazing medium into one cup of acrylic paint. Blend all ingredients well. Your final mixture should be smooth, otherwise you may have unwanted grit on your painted surface, which may make it difficult to write on.
When you paint a surface with chalkboard paint, you will want to use a regular paint brush and make long, even strokes. If you see minor grit in the paint, you can sand it out with 400-grain sandpaper after the final coat has dried.
You'll want to prime the surface for writing after you've finished sanding it lightly. Take a piece of chalk and rub the side along the entire surface, then wipe it clean. Your painted chalkboard surface now is ready to be written on again and again.
Choose a color that will reflect chalk well.
