The instructions were simple, add 1 TBSP of unsanded grout to 1 Cup of paint and stir! (I mixed 2 TBSP with 2 Cups just to be sure I would have enough.)
Then paint onto any surface you want to turn into "chalkboard", We chose to paint the back of Brook-Lynn's bedroom door. The blog (SaltTree) from which the pin lead to and instructions I followed said for a neater appearance to use a roller--she used a brush, so really either would work, but we purchased a roller for this project.
We painted 3 coats on the door, it dried fast and worked GREAT! Cleans up nicely with a chalk brush & a damp cloth or just the damp cloth...I've left just the chalk brush for Brook but using just it by itself some chalk is still slightly visible but I will just give it a wipedown every so often. Hmm now I just need some pink paint so I can make something for myself, haha
