Good to know. I have only used the chalkboard paint for residential projects. However, I have also found using a cheap roller, with any type of paint, will leave a rough surface. Wool (mohair too) rollers are more expensive, but provide a rather smooth surface (also Purdy brushes make a difference too). Plain drywall is fairly smooth. There was a cool video from one of the first Kinect previews on Xbox Live and the family's living room had an area covered in black chalkboard paint with chalked designs all over it. Of course, I am sure this was not a real family, nor their real home.
