Airless spraying is a painting technique that uses a high-pressure pump to atomize paint into fine droplets without the need for compressed air. This method allows for a smooth and even application, making it ideal for large surfaces like walls, ceilings, and exteriors. The equipment typically consists of a spray gun, a hose, and a paint reservoir. Because it can cover areas quickly and efficiently, airless spraying is popular among professional painters and contractors. It also minimizes overspray, making it a cleaner option compared to traditional spray methods.
