How'd we do it? Well, I really wanted the chalkboard to be magnetic as well so I picked up a can of the magnetic primer. Recommended having it shaken at a paint store just before applying so I did just that. Then applied 3 thin coats with a foam roller as the can suggested.
I managed to get a couple splatters on the newly painted wall-oops! Even with taping edges-still need to fix that.
So after all of that, I rubbed an even layer of chalk over the entire board as it recommends "priming" it with chalk so that remnants of writing or drawings aren't left behind with you erase.
Then I tested it out. Magnets are a big 'ol fail. Even the super expensive heavy duty ones. Oh well, waste of $15 for the can of primer. Luckily, I already had the chalkboard paint from a gift I had made someone so the whole thing only set me back $20 after buying a box of chalk and an eraser.
But the chalkboard paint is awesome and we love it! Guess you can tell we are having a girl! And today was Ben's first day of preschool (sniff, sniff-I didn't cry though and luv the school we chose for him).
The only annoying part is that a lot of chalk dust is on the floor after I write on that big chalk board or erase, even though I bough a "dustless" eraser. however, I hear that has a lot to do with the chalk you buy and I only purchased super cheap stuff from Ikea so when I use this all up, I will try a different brand.
