Airless sprayers are painting tools that use high pressure to atomize paint, allowing for a smooth and even application. Unlike traditional sprayers that mix air with paint, airless sprayers deliver paint directly from the container through a nozzle, creating a fine mist. This method is efficient for covering large surfaces quickly. These sprayers are commonly used for both indoor and outdoor projects, including walls, fences, and furniture. They can handle a variety of coatings, such as latex paint, stains, and sealants. Airless sprayers are popular among professionals and DIY enthusiasts for their speed and versatility.
