Most electric airless sprayers are limited to 3300psi. There are certain High Solids paints that require more pressure. The shortest answer would be that you can spray any normal paint through an electric paint sprayer.

Airless spray application creates about 30% overspray or more accurately, bounce back. So, technically you’d use a little more. There is a case for thin film application that is hard to achieve with a roller and in that case a sprayer would use less paint.

An electric airless sprayer doesn’t need an air compressor. However, if you want to get fancy and hook-up an air assist airless spray gun to your airless sprayer in order to achieve a fine spray at lower pressures, then you’d need a small compressor for the air-assist part of the deal.

The top safety rule for using airless spray guns is to never place any part of your body within 5/8” of the nozzle. High-pressure spray can inject paint under the skin, requiring immediate medical attention.

To clean your sprayer after use, use hot soapy water for water-based coatings. For oil-based coatings, check the can for the right solvent or contact the manufacturer for guidance.

To store your pump properly, if you flushed it with water, add antifreeze to prevent freezing and corrosion. If you used mineral spirits, leave them in. Replace any hot solvent with mineral spirits to maintain the packings.
