What is an airless paint sprayer?

An airless paint sprayer is a tool that uses high pressure to atomize paint, delivering a smooth, even coat without compressed air. It’s ideal for large projects like house exteriors or detailed work like cabinets, offering speed and quality. Popular among professionals and DIYers, it requires practice for best results.

No air is used, hence the name Airless Paint Sprayer. 

Key Points

• High-pressure system: Uses a pump to spray paint at 1,000 to 7,000 psi, creating a fine mist (Higher pressures are needed for thick coatings).

• Versatile: Handles various paints, from stains to thick latex, without thinning.

• Efficient: Speeds up painting compared to brushes or rollers.

• Learning curve: Requires proper setup and technique to avoid overspray or clogs.

How It Works

A high-pressure pump forces paint through a small tip, breaking it into a fine mist of paint droplets. This allows for a more efficient and effective application of paint, as it can cover a large area quickly and evenly without the risk of drips and runs that can occur with traditional brushing or rolling methods.

To function effectively, the sprayers require a pressure of between 1,000 and 5,000 PSI (pounds per square inch). The exact pressure required will depend on the spray tip’s size, the type of paint used, and the surface being painted. Due to the high pressure, the sprayer produces lots of overspray.

For example, the Graco Ultra 395 is a 3300 psi airless paint sprayer. Most airless handheld sprayers operate between 1500 and 2000 psi.

Why Choose an Airless Sprayer?

It’s faster than traditional methods and provides a professional finish, especially for large or intricate surfaces. However, due to the high pressure, users must follow safety guidelines, like wearing protective gear.
