Hi Zach Brody, director of marketing at wizard wall, here's another quick tip that'll surly save your walls. If you have a little drawing in the corner of your wizard wall a lot of people tend to erase outwards without thinking, but you want to make sure that you erase outside to inside.On the cinder block, doesn't really matter too much, but if you have a white painted drywall you're not gonna be too happy. So make sure when you erase, go out to in and you should have no problems.
