These girls already have a ginormous dry erase board, but it drives me crazy. Everytime they "need" it for something, like practicing their spelling or playing school, the stinkin' markers are all dried up. I decided to paint the back of their dry erase board with chalkboard paint so they could use both sides - depending on the availability of writing mediums. So, I checked with their mom of course, then I bought some chalkboard spray paint at the craft store. It was only 7 bucks, but then, it only covers 12 square feet. I think they sell cans of it at Home Depot or Lowes that cover more area.
First, we lugged the big board outside and taped the edges with masking tape.
Then we had to wait - a full 24 hours. And that was the hardest part. But after the long wait, the girls had fun "breaking-in" the surface. The spraypaint can said to draw all over the surface with the side of a piece of chalk, then erase it.
