Airless Sprayer vs. Brush for Old House Exteriors
Airless sprayers use high pressure to pump a large volume of paint through a nozzle. This makes them ideal for monochromatic painting jobs. When there is a complicated color scheme on an old house exterior, a simple paintbrush may be a better application tool.

Function
-
The spray pattern from an airless sprayer is about 6 inches wide, on average, from a distance of 6 to 10 inches. This is a useful width for covering large surface areas, but is hard to control when you approach an adjacent surface that you don't want to paint, so you have to mask it. The bristles of a brush, on the other hand, can make a clean line without the need for masking.
Features
-
An airless sprayer covers more evenly than a brush, especially if the house has a grainy siding like stucco. Moreover, because of the high volume it delivers, you often need only one coat. When you use a brush, on the other hand, streaks are inevitable, unless you are applying a stain, and these almost always have to be covered with a second coat.

Considerations
-
Homeowners deciding whether to use a brush or an airless sprayer must consider the size of the house, the siding material, the type of paint they are applying, the number of doors and windows and the amount of trim. The time you spend masking a house for spraying may be more than simply painting with a brush. If the siding is a material that is difficult to brush, however, spraying may be the better choice.
