HOMEMADE CHALKBOARD PAINT. This recipe is super easy and only requires two ingredients…paint (of any color or type) and some Non-Sanded Tile Grout. I found mine at Home Depot for $4 and some change (can’t remember exactly). But you can find the grout at any home improvement store. Then you will need to simply mix 1 cup of paint and 2 Tablespoons of grout. That’s it! Just make sure to stir it really well so that there are no lumps. You can use any paint. Paint for plastics or acrylic paint or house paint. *****You have to use flat paint. *****If there is any gloss to the paint at all, let the paint dry on the object and then go at it with a very fine sandpaper to knock the gloss off. ** Also remember to rub a piece of chalk all over the board to prime it for chalk before using.** If a damp cloth is causing the paint to come off completely, then you used water based paint. Latex paint will also have a tendency to peel off smooth surfaces like glass. I would etch the surface of the glass to be painted. The etching will toughen the smooth surface so that the paint has something to hold on to. For anyone wanting to paint a large area, like a wall or a child’s room, this would be 2 cups non sanded grout to 1 gallon of paint. You can also use any color of paint. How fun is that? There are so many possibilities and price is now no longer a factor! You could paint a whole room in chalk board paint! Your kids would think you were da bomb!
