Last summer we had a lot of fun making sidewalk paint and using it on our patio. I had completely forgotten about this great activity, but apparently it stuck with M, who asked me about it a few days ago. Here’s the oh-so-simple recipe:
1 part cornstarch to 1 part cold waterWe used 2/3 Cups of both cornstarch and water. And we ended up with two good-sized containers worth of paint (a bit bigger than an applesauce or jello snack container). It went fast, so we definitely could’ve used more!
5 to 6 drops of food coloring for each color you want to make.
Just mix the water slowly into the cornstarch. If you are using a whole box of cornstarch, you’ll need to use a whisk or maybe an electric mixer. Pour it into your individual containers, then add your food coloring and gently mix it in. Food coloring will stain clothing so be careful!! It did wash completely off of our driveway with the first rain, so no worries there, although you could always use a dab of washable paint for color in place of the food coloring.
We used regular old paintbrushes and some foam brushes to paint with. It’s fun to watch the watery paint dry quickly in the sun – it becomes so vibrant as it dries! Pretty, pretty, pretty. :)
M drew a pirate ship. Obviously. ;) And some other things I can’t remember. I drew our family and the earth and sun. It’s really hard to resist getting down and having fun with this sidewalk paint – we had a wonderful time doing this together!

Have a beautiful day! :)
