I finally finished my Halloween chalkboard before Halloween. It is a fairly large chalkboard about 2′ x 4′ and is done on 1/4″ mdf. I wish I had a nice Ryobi table saw so I could cut them myself but the guy at Home Depot was nice enough to cut it for me. I wanted to add a nice frame but again no saw.I lightly sanded the front of the board since it sort of had a slight sheen to it and then I painted the whole thing with some homemade chalk board paint. There are hundreds of recipes for the paint but basically it is 1 cup of paint and 1 Tbsp of non sanded grout (I bought a 5 lb box so I have enough to make chalkboard paint for about 500 chalkboards). I added a little bit of water just so it had a smooth consistency-as it had lumps that I had to scrap off and repaint. It really needs to completely dry for about 72 hours-luckily I was going out of town for the weekend so it had time to dry thoroughly. I lightly sanded it with super fine sandpaper and covered the surface with chalk-normally you do that so you can erase the chalk but I wasn’t planning to erase it so I didn’t worry about it being perfect. I will say it is much easier to start with smaller chalkboards but I wanted a big custom DIY Halloween project that would be a statement piece for my fireplace mantle and I love the way it turned out. I did forget how time consuming hand lettering is -eekk!! I made a few mistakes but I am my own worst critic so I won’t mention all of them.
