I’ve seen chalkboard paint, but I’ve never seen dry-erase whiteboard paint before. With IdeaPaint, you can add a dry erase board to walls, tabletops, or other suitable surfaces using just a paint roller. (Professional installation is available, too, for the non-DIYers.) It’s available in the standard white, but it’s also available in black or in clear that can be added over any color. They even offer special white markers for use with black or dark-colored boards. Enough IdeaPaint to cover 50 square feet costs $225. How much would a commercial dry-erase board that size cost?
