Summer is right around the corner! For those of you who are looking for a fun way to enjoy some outdoor kids activities we are sharing our favorite washable homemade sidewalk chalk paint recipe today!

DIY Washable Sidewalk Paint Recipe

One of our all time favorite sidewalk chalk paint recipes is this scented DIY sidewalk chalk. This washable DIY sidewalk paint is a very close second runner up that is a lot of fun.

After making our scented sidewalk paint, we wanted to come up with a bit thicker of a sidewalk paint recipe that would puff up when dried. While this doesn’t puff up like our Homemade Puffy Paint Recipe does, for a sidewalk paint, it puffs up pretty well.

How Do You Make Sidewalk Chalk Paint Washable?

This sidewalk chalk recipe is designed to be a washable paint. In most cases it will wash off during the first rainfall with no issue. If you are concerned about staining you can add a couple drops of a non-toxic soap when making your own sidewalk chalk paint. It is also important to avoid using stronger dyes such as gel food dye to color your sidewalk chalk paints – a couple drops of food color such as McCormick will do the trick and is vibrant enough to reach desired colors.

Ingredients Needed:

  • Corn Starch
  • Baking Soda
  • Water
  • Food Coloring (I would suggest avoiding gel food dyes for this)
  • Plastic Containers
  • Whisk
  • Water

Fun Items To Have on Hand While Playing:

  • Muffin Tin
  • Sponges
  • Paintbrush
  • Foam Brushes
  • Spray Bottles
  • Vinegar


1. In a large bowl, combine equal parts cornstarch and baking soda. Stir to combine.

2. Add a few tablespoons of warm water at a time until the mixture is the consistency of poster paints. You can go as thin or as thick as you would like. Pour in an additional cup of water to thin out the paint if desired. If your sidewalk chalk paint is too thin add up to an additional cup of cornstarch. The thicker the sidewalk chalk paint is the puffier it will be. If using squeeze or squirt bottles be careful not to make your sidewalk paint too thick.

3. Divide the mixture into squeeze bottles.

4. Add food dye to each bottle. Put the cap on and shake the color into the paint. If you would like to use a natural dye we highly suggest these dyes.

4. Take the squeeze bottles outside and invite your little ones to have a blast and make a mess!

Does Homemade Sidewalk Chalk Stain Concrete?

This is such a fun outdoor activity is so easy to clean – just wash it down with a garden hose. If you’re worried about the dye staining, do a small test area first.

You can make this even more fun by adding vinegar to a squeeze bottle and letting your little ones fizz up the paintings. Kids love to watch the chemical reaction between vinegar and baking soda. Plus the vinegar + baking soda chemical reaction is sure to lift out any stubborn colors that may get into the concrete cracks.

How Long Does Chalk Last on Sidewalks and Driveways?

These paints need to be used right away. The baking soda eventually clumps and settles to the bottom so you’ll no longer be able to squeeze the paint through the bottle so make sure you are only making the amount you will need. You can make this in a batch for later if you are planning to use this in plastic containers with a paint brush instead of in bottles. If you plan on doing this you may need to rehydrate your sidewalk paints before use.
