Using an Electric Paint Sprayer
Whether you use a brush, roller, or sprayer, there is no easy way to paint the exterior of your house. When certain factors are right, painting your house with a sprayer will be both easier and faster than with a roller or brush.
- Fast: Once the prep is finished, you are suited up, and the sprayer is primed, spraying goes quickly.
- Coverage: Paint-spraying your house is effective when your house has surfaces that are not perfectly flat or has obstacles such as wires, pipes, eaves, slats, clapboard, etc.
- Prep work: The prep work is long and arduous. Every single part of your house within the spraying range that will not be painted must be masked.
- Post-painting clean-up: Even with proper masking and drop-clothing, you will end up with lots of paint everywhere. It takes about 30 minutes to clean out your paint sprayer properly.
Tools and Materials
Continue to 2 of 9 below.
- Airless paint sprayer: You need the type of airless paint sprayer that draws directly from the can, not the type that requires you to fill up an attached cup. Example of the former: HomeRight Power-Flow. Example of the latter: Graco TrueCoat Pro Cordless.
- Paint: This is your choice, but make certain that it is exterior paint. You can save money and make the job go faster if you purchase 5-gallon cans of paint.
- Clean water bucket: You need a clean bucket that will stay clean throughout the painting process.
- Waste bucket: This bucket will receive drained paint and other dregs of the paint-spraying process. Do not expect to be able to clean this bucket afterward.

Set up the Sprayer in Paint Can and Buckets
All paint sprayers are different. The following is a general guide for placing the various tubes into which buckets:
- Siphon in paint: The siphon is the large tube with a wire screen at the end. Place directly into the paint can with the screened-end at the bottom.
- Drain in waste: Put the drain tube into the waste bucket.
- Plug-in power: Plug in the sprayer to the electric outlet.
Place the waste bucket and paint can side-by-side. This is also a good time to put on your coveralls.Continue to 3 of 9 below.

Prime the Sprayer
Continue to 4 of 9 below.
- You'll likely have a single switch that toggles between "paint" and "prime" modes. Switch it to "prime."
- Switch on the paint sprayer.
- Hold the sprayer trigger.

Quickly Move Drain Tube Into the Paint Can
The pump will run for about 30 seconds. The paint will begin pumping out of the paint can, through the sprayer machine, and out drain tube into the waste bucket. Your paint is on a one-way path.
Quickly switch the drain tube, placing it into the paint can, toward the bottom. The drain and siphon tubes may even have clips that hold them together. Now your paint is making a continuous cycle.
Tip: Keep buckets side-by-side for a quick switch. Buckets are shown here farther apart to make it easier to demonstrate a relationship between the two.Continue to 5 of 9 below.

Wear Maximum Protection When Spraying Paint
Shut off the machine and suit up with the rest of your protective gear. You can't wear too much protection gear when spray painting. Yes, you will look dumb, and it is uncomfortable, but it will save your eyes, skin, hair, and clothes.
Continue to 6 of 9 below.
- Full-body coveralls: Buy the kind with the booties attached. If not, you can buy separate shoe covers or use shoes that you don't mind ruining with paint.
- Goggles: Don't just wear safety glasses, but goggles that seal all-around your eyes.
- Respirator: Don't use just a paper mask, but a HEPA respirator.
- Spray sock: If the coveralls don't have an attached hood, buy a spray sock. It's a simple piece of cloth with a face cut-out, much like a ski mask.
- Gloves: Use old gloves you won't mind getting ruined or latex gloves. Warning: latex gloves will get slippery after a while.

Hold Paint Spray Gun 12- to 24-Inches From Wall
Holding the spray gun closer than 12 inches will result in drips. Holding the gun farther than 24 inches (you can probably even push this to around 30 inches, though) will result in a fuzzy texture and uneven coverage.Continue to 7 of 9 below.

Spray Your Paint in Sections
Using a paint sprayer on your house exterior is like a larger version of the paintbrush. The rules are the same. Mentally divide your work surface into sections. Finish a section and then move onto the adjoining section.
The sections are small enough that the edges stay wet as you move from section to section.Continue to 8 of 9 below.

Always Keep Spray Gun Parallel to the Wall
Paint sprayer instruction books tell you to keep the spray gun parallel to the wall at all times. In a perfect world, you would do this.
In our imperfect world, the gun will naturally angle away, especially at the end of a run. The best you can do is try for parallel, try to minimize these tilts, and try to cover over bad edges on your next run.Continue to 9 of 9 below.

Move Siphon Tube to Clean Water and Flush out Sprayer
When finished, fill the clean bucket with water.
Remove the siphon tube from the paint can, put it in the clean bucket, and switch the paint machine to "Prime" or "Flush." Spray until clean water flows out. You may need to change out the water in the clean bucket about three times for this to happen.
