Though the debate continues over whether a spray-painted finish is as durable as one that has been painted or rolled on, there is no disputing that using a power sprayer is a real time saver. 

Sprayers are a particular convenience for surfaces that would be difficult to paint otherwise, such as shingle siding, latticework, and other surfaces that are textured or have multiple planes.

When you use a paint sprayer, you must protect surrounding surfaces with plastic and dropcloths much more so than if you were using a brush or roller. And do not even consider using a sprayer outdoors if it is even a little breezy. Also follow these tips:

* To achieve a uniform spray with the least amount of pressure, practice on a large disposable surface, making adjustments until you get the setting just right.

* Spray the surface straight on in overlapping strips with the gun about a foot away. Move the sprayer smoothly, about 3 inches per second. When you get to the end of a strip, release the trigger, then engage it again as you reverse direction, taking care not to swing your arm. A steady hand and a consistent pace will produce an even coat.

* Do not take longer than 15-minute breaks or the paint in the sprayer will begin to harden. And when you take a short break, set the safety lock. If you must take a longer break, or you are done for the day, clean the paint from the sprayer according to the manufacturer’s directions after turning off and unplugging the unit. 

* A paint sprayer is a powerful tool, so always wear safety gear, including gloves and googles, and protective clothing such as a durable long-sleeve shirt and long pants. If a jet from a paint sprayer hits a part of the body, it can actually work the paint underneath the skin.
