Things You Will Need

  • Bucket
  • Bleach
  • Trisodium phosphate
  • Rubber gloves
  • Rags
  • 10 pounds hydraulic lime
  • 2 gallons water (for whitewash)
  • 1/4 cup casein powder
  • 1/2 cup sodium borate
  • 3 pounds table salt
  • Paintbrushes

Whitewashing not only enhances the area, but also reduces odors, maximizes absorption of the heat and makes the room appear larger.

  1. Prepare a 7-quart solution, using 1 part bleach to 3 parts water, in a bucket. Add 1-cup trisodium phosphate to the solution.

  2. Wash the basement walls with the cleaning solution and rags to remove any mold and mildew. Wear rubber gloves for protection. Let dry for a few days before whitewashing.

  3. Prepare the whitewash by combining hydraulic lime, water, casein powder, sodium borate and salt.

  4. Apply the whitewash to the walls, using vertical and horizontal strokes. Additional coats may be applied if needed. Allow to dry thoroughly between coats.
