Whitewashing is the process of covering a wall with a very thin coat of thin plaster made with water, lime and other ingredients. Whitewashing is used to color fences, wood, and most commonly, walls. Whitewashing is a fairly historic process, and most individuals choose to treat their walls and fences with more modern paints and finishes. Whitewashing walls is a fairly easy process, and is a project that can be completed in less than a day.


  1. Create a paste by mixing 2 parts calcium hydroxide, also know as hydrated lime, to 1 part water. Mix the 2 ingredients together until the paste is creamy. Let the mixture sit overnight.
  2. Create a salt water solution by mixing 2 parts salt with 1 part water.
  3. Remove any excess water from the calcium and water mixture in the morning. Stir the mixture again until it becomes a thick paste-like consistency.
  4. Add the salt water mix to your paste. Stir well until the mixture is completely blended and has a similar consistency to cake or brownie batter. Continue stirring the mixture, adding extra water if you feel it is too thick. It's easier to fix a solution that is too thick than too thin, so only add small amounts of water at a time.
  5. Test your paste mixture by painting it on top of a piece of paper. Watch it dry, if it dries looking coarse and bumpy, the solution is too thick and more water needs to be added.
  6. Add pigments to your whitewash solution, if you want to have your whitewash colored. Add pigments, purchased from a local hardware store, that can be safely added to any paint or plaster mixture.
  7. Cover your floors with plastic and clean your walls prior to whitewashing and remove any scuffs or stains. These stains can show through after whitewashing.
  8. Wet the walls by applying water with a paintbrush to your walls. This will help the whitewash spread once you apply the whitewash.
  9. Use a wide paintbrush to apply a thick coat of whitewash to the wet walls. It is easiest to apply the whitewash to the tips of the brush and lightly apply it to the wall. You should be aware that whitewash is thicker than paint and doesn't go on as smoothly as interior paint does.


  • Make sure to completely cover you walls and valuable clothing and items in your house when whitewashing, the lime from the whitewash can destroy floors, carpets and clothing.
  • Brushing whitewash should be a more fluid motion than brushing paint as the whitewash is so thick, it can easily clump on the wall, and is not spread around as thick areas of paint are.
  • Whitewash solution will look blotchy after you first apply it, but once it dries it will look brighter and smoother.
  • If your walls have already been whitewashed, you need to remove the old white wash before applying the new whitewash. This can be done with soap, water and a thick sponge.
