Spray guns are tools used to apply paint, coatings, or other liquids in a fine mist. They work by using air pressure or a mechanical pump to atomize the liquid, allowing for an even and smooth application. Spray guns are commonly used in various industries, including automotive, construction, and woodworking, as well as for DIY projects. There are different types of spray guns, such as airless spray guns, HVLP (High Volume Low Pressure) spray guns, and compressed air spray guns. Each type has its own advantages and is suited for specific tasks. Proper use of spray guns can lead to professional-looking finishes and efficient application of materials.
