A spray gun is a versatile and efficient tool used for applying paint, varnish, or other coatings to surfaces. It operates by using compressed air or high pressure to atomize the liquid and spray it evenly onto the target area. Spray guns are commonly used in automotive, woodworking, and industrial applications, as well as for home improvement projects. They provide a smooth, uniform finish and are ideal for covering large areas quickly. With adjustable settings for spray pattern, flow rate, and air pressure, spray guns offer precise control and high-quality results, making them a preferred choice for professional painters and DIY enthusiasts alike.
