Our Papercrete Recipe


When we were researching papercrete, we found many different recipes and mixer-types. After trying various recipies and because we have a clay-based soil on our land, we settled on the following papercrete recipe: 5 parts drained paper mulch 5 parts sifted clay 1 part Portland Cement 1 shake of Borax

  1. Soak newspaper and magazines in water for at least 24 hours (the longer the better).
  2. Sift dry clay (or other soil) on a screen of 1/4 inch hardware cloth to remove the larger lumps and rocks.
  3. After it has soaked in water for at least 48 hours, place the newspaper in mixer, add water and mix well until paper pulp is the consistency of cold oatmeal.
  4. Drain the paper until about 75% of the water is removed (if you capture the drained water, you can reuse it) and add it to a cement mixer.
  5. Once in the cement mixer, add some of the water that you drained off of the newspaper pulp, add the sifted clay and continue mixing, adding water as needed.
  6. Finally, add in the Borax and Portland cement. Continue mixing until the slurry is the color and consistency of chocolate pudding.
