Recipe of Chalkboard Paint:
3 teaspoons acrylic paint (color of choice), PLAIN OLD ACRYLIC CRAFT PAINT WORKS FINE
1 1/2 teaspoons glazing medium (water based)
1/2 teaspoon powder UNSANDED tile grout
USING A SPONGE BRUSH, apply 3 OR MORE coats on your painting surface. Sand with 400 (or more) grit sandpaper between coats, however, if you're careful and use a sponge brush, sanding might not be necessary.
When you're done painting, condition your chalkboard finish by placing a piece of chalk on its side and rubbing down the entire surface. Wipe it clean with a felt cloth and then wipe it again with a slightly damp cloth.
Thanks for the idea!!
