While you can buy premade chalkboard paint at most stores, you can also make your own chalkboard paint, and it’s easier than you might think. Best of all, you can make it in any color you want, so your chalkboard could be hot pink or puce green, for example. How cool is that?
All you need to make your own chalkboard paint is latex house paint and non-sanded tile grout. The non-sanded part is very important. You can get grout at any home improvement store, so you should be able to pick up the paint and grout in one shopping trip.
In the tutorial I am referencing, the batch you make is very small because it is intended for a smaller project. You should be able to increase both in equal amounts and get enough for a whole wall. If I ever get the time and ambition to do this project, I think it would be over the top cool to make squares of different colors, like a big multicolored checkerboard.
This is just another one of those great projects that turns out way easier than you would expect, allowing you to do it yourself for much less money.
