HomeTips DIY: Using Power Paint Sprayers
Power sprayers can save you considerable time, particularly on surfaces such as shingle siding. Although there is some disagreement among paint professionals about whether sprayed surfaces are as durable as brushed surfaces, most agree that if the sprayer is used properly, the finish will last just as long as one created with a brush or roller. The most common paint sprayers, known as airless sprayers, come in many sizes.
Sprayers are particularly useful for painting deeply textured, hard-to-reach, or multipiece surfaces with many nooks and crannies, such as eaves, lattices, or even rough stucco. These surfaces will require you to carefully mask the area and put down plenty of drop cloths. Never use a sprayer on windy or even breezy days.
When using a power sprayer, follow these tips:
* Test the sprayer on a large piece of cardboard, adjusting the unit to get a uniform spray pattern with a minimum amount of pressure.
* To achieve a smooth, even coat, keep the gun about 10 inches from the surface and then spray a succession of overlapping strips. Move the sprayer in a smooth motion and at a consistent pace--about 3 inches per second. Release the trigger at the end of each stroke, and then pull it again as you begin to reverse direction.

* Spray straight at the surface, and avoid swinging your arm back and forth.
* Once you have begun to work, do not leave the sprayer idle for more than 20 minutes or the paint will begin to harden.
* When you have finished painting for the day or are taking a break of significant length, be sure to clean the paint from the unit, carefully following the manufacturer's instructions.
* To avoid mishaps or injury, always wear protective clothing and gloves, as well as goggles. Never point the sprayer head at your body. The powerful jet of paint from a sprayer can force paint through your skin. If that happens, get immediate medical attention.
* Before you clean a power sprayer, turn off and unplug the unit. Then pull the spray-gun trigger to release the remaining pressure in the hose.
* Make sure to set the safety lock on the spray gun when you are not spraying.
