How to Make
DIY Sidewalk Paint for Kids

In a large mixing bowl, add

  • 1 cup of cornstarch 

  • 1 cup of baking soda 

  • Slowly add water and mix to achieve the desired consistency (about 1-2 cups water)

  • Using a funnel, pour the mixture into squeeze bottles

  • Add food coloring to each bottle and shake until mixed well

  •  Let kids loose on the driveway, sidewalk, or school blacktop.

  • The paint applies just like watercolor and dries to a beautiful chalk-like finish.

Do a test patch first. Before your big outdoor painting session, always test the paint on a small, inconspicuous section of pavement. While this recipe is designed to wash off easily, some older or more porous concrete may absorb food coloring. A quick test spot will save you any surprises!

 

 

A light rinse with a hose is usually all it takes to clean up – making this one of the least messy outdoor art activities for kids around.
