This environmentally friendly sidewalk paint takes the place of the traditional sidewalk chalk. Its also very, very inexpensive! This sidewalk paint washes off very easily and will not harm plumbing or plants — cornstarch is all natural and biodegradable. Because this paint is so inexpensive, you can use it to paint larger areas of art compared with traditional sidewalk chalk which is quickly used up. You can also get more detail in the pictures by using different sized paint brushes.


1) Put cornstarch in a small plastic bowl and gradually stir in the cold water.

2) Add your desired food coloring and stir.

3) If the paint still feels too dry, just add a little more water until you get the consistency you prefer.

3) Repeat the process to create different colors. You can make standard shades of red, green, yellow, and blue; or, mix and match to create other shades

If you mix these in small, airtight containers, such as butter tubs or ziploc or Glad containers or Tupperware, you should be able to keep the leftover sidewalk paint from one project to the next — assuming there is any left. If you find that the sidewalk paint has gotten a little dry, just add water to get the desired consistency.

Use sidewalk paint for painting large areas, such as hopscotch grids, make-believe roads and highways, etc. When done, you can wash it away with the garden hose.
