In the dry plaster or fresco secco technique, pigments are usually mixed with water, although other substances might also be used. The paint is then applied to a dry plaster wall which has been wetted down with water. Since the plaster is relatively dry, it is non-absorbent, and the pigment adheres to the surface of the plaster. This technique differs from true fresco (described below) in several ways. The colors tend to flake off the surface of the plaster.
Use a paint sprayer to paint a brick chimney. A brick chimney is masonry, and like all masonry, it is porous. That means it will soak up paint readily and makes an ideal surface to be painted. It is so porous that the best way to apply paint is with a paint sprayer.. Paint the chimney with a finish paint. Spray the bricks liberally and allow them to dry. In many cases you will need only one coat, but if you are using a lighter color, two coats might be needed.
