What I wished that I would have done. I used spray paint. Krylon makes a special chalkboard paint. Also, Rustoleum makes chalkboard paint. I just cured my chalkboard by rubbing chalk over the whole surface and then erasing it. Because of the texture of the wood, I wish I would have used a paint brush instead of the spray paint. I will have to try that next. I had a scrap piece of metal that I could have used, but my dear sweet husband likes metal and he preferred that I use the wood. But really - I like the wood chalkboard. I like it for several reasons - I made it - it will help my children and chalkboards are a thing of the past now that there are dry erase boards.
