Homemade Chalk Paint Recipe – Plaster of Paris

Homemade Chalk Paint Recipe

I love to paint furniture…obviously. What I’ve really started to love is chalk paint. I’ve been addicted to Annie Sloan chalk paint specifically. I can’t get enough. Sadly…I’ve been informed that my addiction to ASCP is causing my husband to develop a complex about our bank account. So what’s an ASCP addicted girl to do?

Make my Own Chalk Paint!

I’ve seen homemade chalk paint in use on various websites by other furniture painters yet still I have¬†wavered¬†on my attempt because, well, it’s Annie Sloan. I mean, am I right? Nothing can beat ASCP.

I’ve heard about using baking soda, unsanded grout, plaster of paris and even a recipe that used real ground up chalk. In all of these, the one I heard over and over again that was the best homemade chalk paint recipe was the one using plaster of paris. There are plenty of others and I’m sure you can google them, but after seeing this one, you may not want to.

If you’ve never heard of plaster of paris before, it’s basically what they use on walls or ceilings to patch up or use to create a nice smooth surface. It can be sanded down when dried and essentially is a plaster…like the name says.

I headed on over to Home Depot to get my supplies. Since chalk paint seems to go such a long way and I like to have different colors on hand I decided to pick up some of the 8 ounce paint samples they have. I’ve purchased the Annie Sloan paint samples in the 4 ounce size, so I knew with 8 ounce I would have plenty of paint to do several projects. The recipes I saw all called for 1 cup of latex paint and since 8 ounces equals 1 cup, I was in business.

BEHR Paint SampleThe helpful guys at Home Depot will mix these little sample paints in any color you want. Seriously, at about $3 per paint pot, you can’t beat this. I gathered up about 5 color samples to try out and now that I’ve finished one project I’m glad I did. One of the ones I had them mix was for a chair I’ve been working on and I wanted a dark gray, almost black finish, so I had them mix up a color called Jet Black.

Next, I picked up a container of plaster of paris. This comes in a sort of school lunch milk carton container looking thing. It gives you a nice easy pour spout although I spooned it out so it’s just handy to close up easily.

My Plaster of Paris Chalk Paint Recipe

When I first followed some of the recipes online, I found the consistency to be a little thick. Honestly, I was afraid of dumping it into my paint. It was super lumpy. So I increased the water just a bit. I ended up using:

  • 1 – 8 ounce pot of paint (this is 1 cup)
  • 2 1/2 tablespoons of Plaster of Paris
  • 2 tablespoons of cold water

I mixed the plaster and water into a small plastic dish and stirred it up with a spoon until it was smooth…almost reminded me of pancake batter. Then I dumped it straight into the sample paint pot and stirred it up until it was completely mixed into the paint.

Next, I grabbed my paint brush (yes, I did use my Annie Sloan paint brush…which you will take from me when you pry it from my cold dead fingers) and applied it to my chair. I have to admit, I was completely shocked. It went on just like the ASCP. It also dried super fast and when it did try it had the same chalky appearance that the other stuff had. Honestly, I just couldn’t tell much of a difference. I used one coat and then applied my finishing wax and it was pretty awesome. You can see in the picture below, I just finished painting the arm which is still wet, but the bottom of the arm support is dry already!

How Much Does Homemade Chalk Paint Cost?

I spent just under $7 on a full container of plaster of paris. It’s 4 pounds, and I used 2 1/2 tablespoon so according to my Google tablespoon to pounds conversion I dropped about $.15 cents on plaster of paris. Add to that my $3 on the paint and I’m up to about $3.15 for a full 8 ounce pot of chalk paint. In the past, I’ve spent around $12 plus shipping for a 4 ounce chalk paint sample size from Annie Sloan. So, I can now have 8 ounces of paint for $3.15 or $24 plus shipping with ASCP.

Final Thoughts

I’m not gonna lie, I loved this stuff. It was super easy to mix up and oh my goodness…the savings! The other thing to keep in mind is that when you make your own chalk paint, you aren’t limited to the colors available from the other chalk paint makers. The sky is the limit here folks.

I still have quite a bit of inventory in my garage of Annie Sloan paint in my garage that I will definitely make use of and I definitely still love the brand and paint, but I can definitely see myself switching things up when I run out of my favorite colors.
