The post is from 2011. A Loooong time ago. We have easier solutions now. No painting no building etc.

Visit walmart they have a big sticker like chalk board you just peel the paper cover (same as the stickers) and place it where you like I bought two I placed one on a metal (for magnets); and one to be used as an inf. Board.

The thing lasts for ever it is water proof. My kids use it just as a regular black board.

My inf. Board is also becoming obsolete, this year will change it for an interactive digital board.
