DIY sidewalk chalk

DIY sidewalk chalk it is cheap to make and you can make any shape you want! You only need three ingredients and a mold and you are on your way to non-stop summer fun!


  • Plaster of Paris dry powder, not mixed. They have this at Michaels
  • Tempera Paint have fun with the colors!
  • Silicon Mold
  • Water
  • Disposable Cups
  • Plastic Spoons


  • For each color you will need a separate cup.
  • Fill each cup with 3/4 cup of water.
  • Add 1/4 cup of paint
  • Add 1 cup of Plaster of Paris
  • Mix well
  • Pour mixture into molds (I cleaned up the edges with a paper towel)
  • If you want to layer colors just pour the first color in and add the second or third on top (see picture below - don't mix them)
  • Let dry for 24 hours. Remove them from the mold (be careful because they are still soft and you need to carefully pop them out). Let them dry outside the molds for an additional 24 hours!
  • Presto - your own homemade sidewalk chalk!!!! So fun!!

  1. Has anyone used this as sidewalk chalk paint? I know you’d need to use as you go before it sets up.

  2. I have made my own chalk using a similar recipe but it always seems so toxic and dangerous to let kids help. My question is does it not eat through your mold? I have tri d putting the chalk mix in different containers and it always eats through and leaks

    1. Hey Gabby – I haven’t had that problem. I actually left it in the mold for a week once and it didn’t eat through.

      1. OK awesome I have new Lego brick silicone molds I just didn’t want to ruin them. Thank you and I love your posts!

  3. Sure one could just go buy chalk at a dollar store. But this way, one can get the kids to help make it and give them a project to do as well! My grand babies would love making their own sidewalk chalk! Besides a great way to spend time with the kids without boring them or parking them in front of a TV or some kind of game system!!

    1. This was my exact thought. Why would I mess up my kitchen and buy expensive tempera and plaster when I can get a bucket of chalk for $1? Maybe I’m lazy but I have three kids and making my own chalk feels like an incredible waste of one’s time.

  4. In the picture it looks like the molds have been spray with cooking spray, d
    o you need to spray the molds before putting mixture in them?

    1. Just went to make this and on the box of the plaster it cautions not to breathe the dust and to avoid skin and eye contact . Also to wear gloves and eye protection while working with is wet because it can cause burns! Yikes!
      I’m hoping this is only true of the brand I purchased (DAP) and not all kinds if people are making this with/for toddlers and young children! Bummer.

  5. my question is, your recipe adds up to two cups, but it appears you are using red “solo” cups. Did I miss something?
