How to cast concrete in folded paper forms

What you will need: 

  • Heavy paper stock (such as photo paper)
  • Pre-mixed concrete (the finer the aggregate, the better) 
  • Water
  • Tape
  • Scissors or an X-acto blade

How to make it:

  1. Download a foldable form or make your own using Pepakura Designer.
  2. Cut out your form and tape it together, making sure to leave a hole at the top for filling it with the concrete mixture. 
  3. In a disposable cup, add enough concrete mix to fill your form and then slowly mix with water until it reaches the consistency of a milkshake. 
  4. Pour concrete mixture into the paper form.
  5. If possible, seal and tape your paper form closed (concrete does not require exposure to air in order to cure). 
  6. Let concrete cure for recommended time suggested by the manufacturer.
  7. Open up the form and remove your concrete sculpture!
  8. Finish edges with a coarse file and wet sand to desired smoothness. 
  9. If desired, seal with lacquer or clear nail polish.
