Wow, this stuff is great! We painted a part of one wall with chalkboard paint, waited 3 days, conditioned it with a piece of chalk and it works great! The paint isn't expensive, but we already had a can from when we purchased the house. It can be used on so many surfaces. We hardly used any to paint this wall, so we have plenty left over. I will probably do an area in each of the girl's rooms. I might also do an area near the kitchen to make notes and lists.
