The purpose of exterior painting in every Tucson home or building is to make them look better and/or to protect it from damage by water, rust, corrosion, insects, and mold.
Modern paints result in latex formulations being widely used for exterior as well as interior. That reduces post-painting cleanup, and reduces the smells associated with petroleum and polyester-based paints. Computerized paint scanners formulate new paints to match the often-faded color of existing paints. Modern paints are available in various specialized formulations that can be fade resistant, chip resistant, and odor-free to resist mold and fungi growth.
