Airless paint sprayers
allow users to complete jobs more efficiently.
Airless paint sprayers work by pumping paint through the paint sprayer tip, and this type of paint sprayer do use air compressors or other types of pressurized air. The paint is forced into small tips via pressurized hoses. Airless paint sprayers rapidly release a lot of paint and allow paint jobs to be completed quicker than hand painting. Proper use of airless paint sprayers includes using the correct painting techniques and using the right sprayer tips.
Tips
The size of airless paint sprayer tips affect how much paint comes out of the sprayer. The general rule is that the smaller the tip, the less pressure put out by the hose, allowing you to have more control over the spray. Read the manual to find out the recommended tip size for the job that you are doing, and then go one size smaller. This will give you additional control over the sprayer. Change tips after four or five uses since tips will get larger, and control will be decreased. Use reversible tips as opposed to the cheaper flat tips. Reversible tips can be cleaned and reused more often. Always clean all parts after use to reduce paint build-up and clogging.
Spraying Technique
New operators must rehearse before using a gun. Practice on a piece of plywood or other flat surface to nail down your technique. Use horizontal strokes with the spray gun positioned at an angle for inside corners. Use banding (vertical strokes) on surfaces connected to outside corners and on smaller and vertical areas. Use horizontal strokes on sections that are long and flat, including the walls of residences. Employ thin spray patterns on round shapes kitchen table legs, using long strokes on small or medium circles and short strokes on large circular objects.
User Technique
Use a tight, but natural grip, and operate the gun with the index and middle fingers for optimum control. Stand with legs about shoulder-width apart with one leg slightly behind the other; this will allow you to easily pivot back and forth. Stand approximately one foot back from the object that you are painting. Any farther back will result in patchy coverage and possibly over-spraying. Always hold the sprayer perpendicular to the surface that you are painting for maximum coverage. To avoid overlapping, point the gun at the bottom of the previous layer. If you need to go slow in order to get full coverage, increase the fluid pressure slightly. Do not, however, turn up the pressure too much. You should turn the pressure down as low as you possible can without getting uneven coverage.
