How to Make Chalk Paint with Recycled Sidewalk Chalk
Learn how to make homemade chalk paint with the easy step-by-step directions below.
Step 1 – Collect sidewalk chalk
- Round up the kids and invite them to collect small broken and water-soaked pieces of chalk to make homemade chalk paint. New sidewalk chalk can also be used if you don’t have enough broken pieces.
Step 2 – Sort sidewalk chalk by color
Get the kids involved in the next step in the recycled chalk making process with this simple color sorting activity:
- Invite your children to sort the chalk by color into a muffin tin or another container that would work to hold the chalk for color sorting!
- Once they are finished, move on to the next step.
Step 3 – Put each color of sidewalk chalk into a separate freezer bag
- Place the chalk into freezer bags.
- Make sure that each color of broken sidewalk chalk is in its own freezer bag.
- Freezer bags are recommended because weak bags can rip and tear in the next step.
Step 4 – Crush sidewalk chalk into a fine powder
- Wrap each bag of sidewalk chalk in a small kitchen towel and use a rubber mallet or a small hammer to gently crush the sidewalk chalk into a fine powder inside of the bag.
Step 5 – Put sidewalk chalk powder in containers
- Add the powdered chalk to an old muffin tin or recycled container.
- Recycled sour cream, cottage cheese, and yogurt containers work great for this purpose.
- Put one color of chalk powder into each muffin compartment or container.
Step 6 – Add water to sidewalk chalk powder and mix.
- Slowly pour water into the chalk powder one color at a time.
- Next, mix the chalk powder with a paintbrush or chopstick while pouring slowly.
- You want your DIY chalk paint to be the consistency of pancake batter.
- Start with less water than you think and add more if needed.
- If your homemade chalk paint is too thin, crush up some more sidewalk chalk and add it to the chalk paint in order to thicken it.
6. Allow recycled DIY chalk paint recipe to sit
- Give your homemade chalk paint about 30-60 minutes to sit and settle.
- After your colored chalk paint has settled for a bit, use a chopstick to stir it up and crush the chalk chunks before painting with it.
Homemade Chalk Paint Tips and Tricks
- When using homemade chalk paint it’s best to have water available to continue to add to the chalk paint as you work. Why? Because recycled chalk paint loses its water content as you work. This makes the paint thicken, so you will more than likely need more water. Just keep pouring water into your recycled chalk paint as needed. We kept a little metal pitcher near where we worked to easily add water whenever our chalk paint started getting a little dry.
- Another interesting thing about painting with chalk is that the colors always look a bit paler when they are wet than when they are dry. No big deal, just let the kids know that their sidewalk chalk paintings may look a bit different when they are dry–and you might prevent a meltdown.
- Recycled chalk paint will often have a few chunks of colored chalk pieces left in it. So, if you find any little chunks in your chalk paintings, use the handle of a paintbrush to crush them. Then use a little water to mix them into the chalk paint as you work.
- I don’t recommend using this chalk paint recipe on a vertical outdoor chalkboard because it can run. This homemade chalk paint recipe is best to use on flat surfaces like driveways, sidewalks, and playgrounds.
