Airless spray guns are specialized tools used for painting and coating surfaces without the need for compressed air. They work by using a high-pressure pump to force paint through a small nozzle, creating a fine mist that evenly coats the surface. This method allows for faster application and reduces overspray, making it ideal for large projects. These spray guns are commonly used in both residential and commercial settings, including construction and automotive industries. They can handle a variety of materials, such as latex paint, stains, and sealants, providing versatility for different painting tasks.
