Airless spraying is a painting technique that uses a high-pressure pump to atomize paint without the use of compressed air. In this method, paint is forced through a small nozzle or spray tip at very high pressure (typically between 1,500 to 3,000 psi), creating a fine spray fan that evenly coats surfaces.
This technique is commonly used in the painting and decorating industry, especially for large surface areas such as walls, ceilings, fences, and commercial buildings. It allows for faster application, a smooth finish, and better coverage compared to traditional brush or roller methods.
Key features of airless spraying:
- No compressed air required – relies on hydraulic pressure.
- High efficiency – covers large areas quickly.
- Smooth finish – ideal for both interior and exterior surfaces.
- Versatile – suitable for a wide range of coatings including acrylics, enamels, stains, and primers.
In Australia, airless spraying is widely used by professional painters and contractors for both residential and commercial projects.
