    We painted an entire wall in our granddaughter's playroom at our house. First we made sure the wall was nice and smooth. Then we primed it really well. We bought the paint tinted to a darker shade of green than the rest of the room, taped off where we wanted it to end at each corner and at the top and then rolled it on. Let it dry between coats. The guy who mixed it for us at Home Depot recommended at least three coats. Then after it had dried for several days (we were working on the playroom on weekends) we "seasoned" it by rubbing chalk one direction, all over, and then the other direction. Then you wipe it off, and you have your chalkboard surface. We love it and more importantly she does to. I had the green and pink color combo for the room picked out from the valances and throw pillows I found for the room. I only mention that, because the guy who mixed the paint said it could be tinted any color.

      @Cynthia H Thank you for your help! My problem is that the wall surface must not have been smooth enough so when I seasoned the painted wall the chalk, the chalk won't erase well...it's in the tiny "pits" in the wall. (wall is a little like the skin of an orange). How did you smooth your walls before you primed (I did not prime...)? Our walls are drywall. I sanded lightly by hand first. Thinking I should have used an electric sander... Thanks for any suggestions!

    After you paint anything with chalkboard paint, you have turn the chalk on its side and rub it all over the painted surface to prepare, then wipe it off, then it is ready for writing.

      Hi Tobey, thanks for the reply! I did season with the chalk after painting as you said. I think the wall has tiny bumps so chalk fills them up and leaves a lot of white showing through even after wiping off with damp rag. I am wondering if I didn't prepare wall surface well enough? Maybe I should have sanded wall with electric sander and primed first. I only sanded by hand.

    We hand sanded and wet sanded until we got the wall as smooth as possible before priming. Had to wipe it down very carefully with a damp microfiber cloth to make sure I got all the dust, too. Our wall was fairly new (unlike the rest of the house), but, a light skim coat can be smoothed out to level the wall, too. It's time consuming and I spent hours working on that wall. Had you thought about repainting the wall after smoothing it out? Personally, I'd be afraid to use an electric sander on a wall, as you might damage the paper on the Sheetrock, depending on how much you remove with the sander. My best advice is to work on it a section at a time, and don't rush it, as the final result will show all your hard work. I would run my hand over it, to make sure it was smooth enough and even looked at it with extra lighting. Sometimes I just had to walk away for awhile. Maybe you can find some repair suggestions here at Hometalk. Try searching with words like skim coat and repair drywall. Lots of luck to you!
