When we moved into our current office we wanted huge whiteboards since we end up using them for all kinds of notes, illustrations, todo lists, etc. We looked at large boards and they were terribly expensive to ship and a pain to mount. We also looked at whiteboard paint and things similar to what’s mentioned in the article but found lots of issues with erasure, ghosting, and staining over time.

We ended up using custom printed ThinkBoard [1] stickers. We were hesitant at first but the price is relatively cheap for the size and we got them printed with our company logo with a high transparency value so it wouldn’t distract when writing over it. I can honestly say that they are amazing! We put up 2 so far. One is ~12ft x 4ft and the other is ~16ft x 5ft. We’ve been using them for over a year and have no staining or ghosting issues and we regularly leave things on them for weeks at a time. One swipe with the included microfiber cloth and it looks as good as the day we put them up. It’s basically just a big sticker so it’s pretty easy to install with 2 people. I’m not sure yet how the wall will fare when we peel them off but I imagine it won’t be bad. We also sanded the wall behind where we stuck the second board to remove any paint bumps or inconsistencies and it’s really slick. I wouldn’t say it’s required but if you have a little time and a sander I would recommend it.
