For this method, the sponge is dipped into the paint and blotted onto the wall in a random pattern to create texture. Some painters apply the paint to the sponge with a brush rather than dipping the sponge into the paint. This allows for more control and limits drips. A natural sea sponge is the most popular tool; however, other natural fiber tools such as lamb's wool applicators can be used to create different types of textures.
Apply the second coat of paint with a brush or roller, then sponge it off with a sea sponge or other tool to create a different type of look. For this method, the sponge should be dampened and rung out. It's best to work in small sections and to wash the paint off the sponge frequently. When moving from one section to the next, take extra time to carefully blend the edges of the two sections.
There's no rule that says only two layers of paint can be applied. When using either the sponge-on or sponge-off method, three or more layers can be added. Make the color slightly darker or lighter with each layer by adding different amounts of faux glaze, or be bold and select colors that contrast more sharply. Allow each layer to dry completely before applying the next. Also consider applying subsequent layers very lightly to allow more of the previous layers to show through.
Sponges can be used to create distinct shapes on your wall. Cut your own shape out of a synthetic cleaning sponge or buy specialized sponges from a paint supplier. They are available in a wide variety of shapes and sizes, such as animals and stars. Apply a small amount of paint to the sponge and stamp the shape onto your wall.
Rather than using the sponge to create shapes, consider using painter's tape or other materials to create a design and sponge paint only a certain section of your wall. Or, use a straightedge to create a geometric pattern. Combine this method with the layering technique to apply different numbers of layers to different sections of a geometric design. Experiment and keep in mind that you can correct any mistakes simply by applying a new layer of paint.
