If you have five minutes, you can whip these up for a full afternoon of sunny sidewalk and driveway decorating. We even have a little variation on the recipe you can use to create spectacularly fun summer sidewalk paint potions (a quick science lesson for young magicians in the making).

To make your own DIY sidewalk paint you’ll need:

  • 3 cups of water
  • 3 cups of cornstarch
  • Food coloring (as an alternative to standard food coloring, you can use natural food coloring like this, or gel food coloring like this for more vivid colors. )
  • Small containers (recycled plastic containers with lids, small bowls, a muffin tin, etc.)
  • Paintbrushes (all sizes)


DIY Sidewalk Paint Instructions:

  1. Mix cornstarch and water in small containers

    Using a 1:1 ratio, mix cornstarch with water. We mixed 3 cups of water with 3 cups of cornstarch, then divided the mixture into 6 silicone baking cups to use for six different colors. This gave us plenty of paint for one kiddo to play around with, yielding roughly 1 cup of paint in each color.

    You can use recycled plastic containers (with lids if you’re going to save your paints for a day or two) small bowls, a muffin tin, baking cups – whatever you can find that’s appropriately sized and safe to take out to the driveway or sidewalk.

  2. Add food coloring

    In past projects, I’ve found that I prefer the bright, vivid colors I can get with gel food coloring over the standard liquid food coloring. It’s usually available in pre-mixed, fun colors that can be hard to reproduce with the liquid, and it’s also more concentrated, requiring less product for bolder results. Add gel coloring 1-2 drops at a time, mixing well, until you’ve achieved the color you’re looking for. If you prefer to use liquid food coloring, here are some color formulas that work fairly well…

    Bright Green: two blue drops + four yellow drops
    Vivid Purple: three red drops + two blue drops
    rilliant Orange: three red drops + three yellow drops
    Radiant Yellow: five yellow drops + one red drop
    Bold Brown: three red drops + three blue drops + three yellow drops

    Note: We found this was easy to completely wash off of our driveway with a hose and didn’t leave any sign of color-staining, but it’s always a good idea to test some small dots of paint on the area you’ll be painting on first. The material and porousness of your painting surface, along with the kind and amount of food coloring you’ve used, can create different results.

  3. Head outside and paint!

Make Magic Sidewalk Chalk Paint Mystery Potions!

Years ago, our friends at ARTifact in San Francisco came up with a super cool variation on this sidewalk paint for us that kicks the fun up a notch with an amazing color reveal! Invite your kids to play magician and use a bit of science sorcery to create their own magic sidewalk paint potions that go from plain old white powder to fizzy, fantastical magically-colored paints.

Magic Sidewalk Chalk Paint Potion Recipe:

  • Fill a small container with 1/4 cup of corn starch and create a crater in the center of each with a finger.
  • Squeeze 3-4 drops of food coloring into the crater. You’ll notice that the corn starch will ball up around the drops of color.
  • Instead of adding water and mixing before use, cover up the food coloring drops with another quarter cup of cornstarch.
  • When you’re ready for the big reveal, take your cornstarch-filled containers outside and place them on the ground (you’ll want to make sure your kids can see this part…). Add a tablespoon of vinegar for a bubbly, colorful reveal!
  • Finish by mixing in a half cup of water – you’re ready to paint!

For a fun gift idea, wrap each container in a square of tissue paper and tie it with a ribbon. Tie on a paintbrush and these instructions: “Mystery Sidewalk Potion: To paint the town, mix one-part potion with two parts water and watch the paint reveal its true color.”.

More Ways to Use Your Sidewalk Paint for Kids’ Summer Play

  • MIX COLORS. Use a spoon or eyedropper to explore color mixing.
  • SPRAY, SQUEEZE, OR SPONGE. Why stick to basic paintbrushes when you could explore a few other ways to paint?? Pour your sidewalk paint colors into spray bottles or squeeze bottles and experiment with making different kinds of marks with your paint. Get out some sponges and see what happens when you sponge-mix mix or sponge more water onto your paint. How much water can you add before your paint washes away?
  • FREEZE IT! This simple modification invites kids to cool off and enjoy some chilly sidewalk sensory play. Freeze individual colors in paper cups or silicone baking cups (you can add popsicle stick “handles” if you’d like) then take them outside for a fun melting paint experience.
  • USE ON PAPER. Nervous about marking up the driveway or don’t have a great spot to paint? You can use these paints on paper too! Experiment with using your paints on lighter colors AND darker colors (I found the colors really pop on black construction paper).
