An airless sprayer is a painting tool that uses high pressure to atomize paint, allowing it to be sprayed onto surfaces without the need for compressed air. This method provides a smooth and even finish, making it ideal for large areas like walls, fences, and decks. Airless sprayers can handle various types of coatings, including latex and oil-based paints. These sprayers consist of a pump, a spray gun, and a hose. The pump draws paint from a container and forces it through the hose to the spray gun, where it is released in a fine mist. This technology is commonly used by professional painters and DIY enthusiasts for efficiency and speed.
