Question: How difficult is it to repaint over Chalkboard paint should I decide to repaint in the future?
Document: I made a chalkboard paint wall in my kitchen using this paint. An entire wall is the school kind of color green chalkboard. I get compliments on it every time someone new is in my kitchen.I use it every day.A few notes:1. Sand. Then sand some more. The wall you paint needs to be extremely smooth, because chalk is difficult to erase from bumps and divots.2  Use a good roller. The instructions provide a good nap length.
Oops, guess I needed to practice a little more. No biggie! With the determination of a newborn foal, I grabbed my kids' chalkboard eraser and cheerily wiped at my drawing. EXCEPT IT WOULDN'T.COME.OFF. The surface was rough and difficult to erase.
If you want some functionality and want to be able to erase and write multiple times, this isn't for you. I had to go with a dry erase board after this. And had to repaint my wall.
The only con is that coating with the chalk causes a huge mess. This maybe because the chalk was dollar tree but I think in the future I will get dustless chalk.
I can't wait to use this for my wedding glasses and my wedding crafts! Love this chalkboard paint and can't wait to use it!
This is my favorite paint to use on chalkboards. Not to mention it also looks great and smooth once on, like a real chalkboard. I always re-purchase this when I am doing little projects or gifts.
Even with using a foam roller to apply it, it is not smooth enough to erase chalk easily. We had magnetic paint underneath bit I sanded I it before putting on the chalkboard paint. Maybe I didn't get it sm
I followed the instructions to a T.  No matter what I do, chalk pens don't come off without adding another coat of paint. Even chalk has a hard time coming off. If you planning on using this every day, I would invest in a real chalkboard.
I bought this for a chalkboard on a door. I wanted it magnetic but read horrible reviews on how the magnetic primer did not work so i put this on a piece of sheet metal that I then attached to the door. I did a coat of primer on the metal then sanded. I then followed up with 3 coats of chalk board paint and it worked flawlessly.
I was very pleased with this product. The price was a little high but was worth it considering the price of buying a new chalkboard. I took a half inch piece of plywood that was 4x8 and primed it with white primer twice. Then I painted it with the chalkboard paint twice and waited 3 days. It works great and the kids love it!
