... if you're using Idea Paint. This great product is the invention of three undergrads (John Goscha, Jeff Avallon and Morgen Newman) who back in 2002 couldn't afford whiteboards for their brainstorming session in college. So they came up with the idea of creating paint that transforms virtually any surface into a dry ease surface. 
The process is quite simple. The paint comes in a kit including everything you need to make your own dry erase surface. All you need to do is pour the bottle labeled "THIS" into the quart labeled "THAT", stir it with the provided stick and paint any primed surface of your choice. The paint dries relatively quickly but you should wait for it to cure for a couple days before using it. What makes this product so attractive, beside the fact that it allows us creative types to unleash our creativity beyond a limiting piece of paper, is that it erases easily. 
Idea Paint is a great alternative to blackboard paint and comes in a couple different color options. There's so many great possibilities with a product like this : offices, kindergartens, common rooms, conference rooms, play rooma, teenager's bedrooms, etc. 
I'll have to try it out at some point. Maybe I'll start with the sample...
