Although it makes use of 3-4 colors, sponging on is probably the easiest way to make a wall look rich with texture and dimension. It uses a sea sponge, a scrap cardboard substrate to remove excess paint and 3 or more colors for effect.
Prepare with your base coat- usually a color that is markedly lighter than your complimentary colors that will be sponged on.
Beginning to Paint:
Using your paint brush, apply your darkest color on the sea sponge. You cannot dip the sponge directly into the paint as it will ruin the subtly effects the sponge provides. After you have applied the paint to the sponge, gently pat it twice on your scrap piece of paper or cardboard to remove excess paint.
Applying the First Coat:
Gently contact the wall with the sea sponge, turning it slightly with each pass. This eliminates a “predictable” pattern. Completely cover your wall using this motion.
Make Sure the Sponge is Clean:
After about 15-20 contact motions with the wall, wash your brush with water. A good idea is to purchase two sponges in order to allow one to dry while the other is being used for further painting.
Applying Subsequent Coats:
Using the same light contact, twisting technique, apply your other colors, taking up with the next lightest color. The more colors and passes used- the more realistic and deep the texture will be.
