Stone Washing on Textured Plaster

With our large color selection of Ochers and pigments, Stone Washing and then sealing is a cost effective, easy way to create washes of color that can be varied in intensity to create a stone like look. If new to this type of finish, be sure to test until you get the ratios and technique mastered. Ocher and pigment colors can be intense so start sparingly with ratios and work up. Creating a wash with only water means that the color will not be fixed once dry, allowing further manipulation of the finish before sealing.

Ingredients

Tools Needed:
  • A flat, professional cellulose sponge available at home decorating centers such as Home Depot. Other types of sponges will not work as they may leave streaks or excess powder on the surface.
  • A brush (optional)
  • A short pile roller for sealing
  • A bucket for mixing plus a stirrer (whisks work well)
  • Water
  • Ocher or pigment color(s) of choice
  • Clear Sealer
  1. Choose the Ocher or pigment color(s) desired.
  2. Mix the powder into water at a ratio of up to 3 tablespoons Ocher or pigment to 1 quart of water and mix thoroughly. This Ocher or pigment ratio can be decreased to lessen the intensity. The color will disperse in the water but will try to settle to the bottom, so continually stir during application.
  3. Using a brush or a damp, flat cellulose sponge, rub the pigmented water into the surface, accenting the variations in the texture.
  4. Once the desired color has been achieved, you can immediately wipe any areas that are too dark or need more manipulation.
  5. Allow the wash to dry at least 15 minutes. Once dry, the color will not be fixed to the wall and will still be dissolvable with water should any reduction or corrections be necessary. Use your WELL-WRUNG, flat cellulose sponge to distress the finish, reduce the color or add a second color. When applying a second color, care must be taken to not disturb the first color. If the sponge is too wet, or the second color worked too much the two colors will blend and muddy, or the first color will be removed. If over-wetting of the surface should occur, allow the wash to dry completely before returning to make corrections. Allow color to dry completely before proceeding to the final step of sealing.
  6. Your new wash must now be sealed in order to make it permanent. Apply a clear sealer of your choice with a short pile roller in one coat.
