Make your own giant pavement chalk

Kids can have hours on fun with this giant pavement chalk. They can use on a concrete patio or driveway, out on the pavement in a safe area, or buy a can of Rust-Oleum Chalkboard Spray and paint a section of wall, or board, for mounting to a wall, where the kids can play.


Tempera powder paint in primary colours
Plaster of Paris (at hardware stores, craft and hobby shops)
Wrapping Paper Tubes
Wax Paper
Masking Tape
Ziploc bags or piping bags
Optional: Rust-Oleum Chalkboard spray

Find all the supplies you need for this project at your local Builders Warehouse.






1. Cut the tubes to a length of about 10 centimetres. Line inside the tubes with a piece of wax paper and then tape the base closed with masking tape.

2. For each colour mix 2 to 3 tablespoons of powder paint with half a cup of water. Slowly stir in the plaster of paris until nice and smooth. The mixture should be not too runny - slightly thick.

3. Spoon into a ziploc or piping bag and snip away the corner.

4. Use a bowl to support the tubes while you squeeze the mixture into the tubes.

You can mix the various primary colours to make more colours.

5. Allow the mix to set in a warm, dry place for 24 hours and then gently peel away the tube and wax wrapping.
