How to Make Homemade Plaster for Walls

Tara Dooley

If you are redoing a wall or walls in your home, there are many textures and materials that you can use to get the look you want. Consider making a clay plaster for the walls that you can apply and spread as you wish. It will give the wall a red clay southwest feel and can be textured like regular plaster or stucco.

Create a one-of-a-kind look with clay plaster on your walls.

It is made of natural ingredients and is a lot cheaper to use.

  1. Dig down about 2 feet in the ground in an area that has clay soil.

  2. Remove a bucketful of soil at this level.

  3. Fill a separate bucket one-third full of water, then add the clay soil from the first bucket. Add soil to the second bucket until it's three-quarters full.

  4. Stir to break up big chunks and then let it sit for a full day.

  5. Stir it the next day to mix it well.

  6. Strain the mixture through mesh into a clean bucket to remove sand and rock. Use a 1/4-inch mesh for a base plaster and 1/8-inch mesh for a finishing plaster.

  7. Mix the watered clay with fine sand to achieve the texture of plaster. This generally results in from 1 part clay mix to 9 parts sand up to 2 1/2 parts clay mix to 7 1/2 parts sand.

  8. Dampen the wall by spraying it with a spray bottle before applying the plaster.
