Step 1
Consider the type of paint task you are taking on. If you need to reach higher, be sure a long hose is available with the paint sprayer. The size of the sprayer's holding container also matters. For larger jobs, especially when on a ladder, you need a larger container to hold the amount of paint needed, or a hose extension to feed a constant supply of paint to the nozzle.

Step 2
Determine the type of paint you need before purchasing your paint sprayer. If you are using oil based paint, choose a compatible nozzle.
-
Step 3
Look at both air and airless models of sprayers. Both offer advantages depending on the job you are doing. Airless sprayers don't require the use of air compression, but instead rely on pressure to push the paint out. The difficulty here is that you need to maintain the right amount of pressure to get an even amount of paint out throughout the spray. Air paint sprayers do use air compression, making them more expensive, but they give a more even coat of paint.

Step 4
Find out what PSI, or pressure level, the paint sprayer has. Even in used paint sprayers, this information is often available on the packaging or on the sprayer itself. The more PSI the unit has, the more power it has. In most residential use sprayers, look for a maximum PSI around 2800.

Step 5
Inquire about maintenance. When purchasing a used paint sprayer, the level of maintenance completed on the unit determines how well the sprayer will work in the future. The nozzle hose and virtually every component needs to be thoroughly cleaned after each use to avoid clogging.

Step 6
Check out the unit thoroughly for function and cleanliness before making your purchase.
