We’ve put together a comprehensive guide on how to use a paint sprayer for you. This will cover airless paint sprayer, HVLP sprayers and spray guns with compressors.
Once you’ve finished reading through these instructions, you’ll be ready to use a paint sprayer like a pro.
Airless sprayers pump more paint at high pressures, oftentimes up to 3000 PSI. The airless sprayer tip is designed to break up the paint evenly into a spray pattern made of small droplets.
Some models of airless sprayer, such as Graco paint sprayer and Titan brands, will offer the ability to spray directly from a 1 or 5-gallon bucket. This means you can get the projects done faster with great spray pattern.
Here are some simple steps to follow when learning how to use an airless sprayer.
Completing household painting project is easy and quick with the right paint sprayer and spray pattern. Once you’ve determined the right model of airless paint sprayers for your needs, you have to learn how to use a paint sprayer.
While this can seem intimidating at first, it doesn’t have to be. Most models, especially those geared toward home users, are simple to use, setup and clean. With a little practice spraying, anyone can become more paint spraying professional by using a same technique.
Prime The Pump
Place the small prime tube in an empty bucket and put the suction tube into the strained paint. Turn the valve to “Prime” and switch on the pump.
When the paint flow begins, move it into the paint bucket or paint container. Hold the paint spraying gun over the empty bucket and pull the trigger. Continue until the paint begins to flow at a steady stream.

Choose Your Spray Tip Size
Most sprayer tips are labeled with a three-digit number such as 517. By doubling the first number, you can determine the spray fan width when the gun is held 12-inches from a target surface.
For example, the 517 would have a 10-inch wide fan pattern. The other two digits determine the size of the spray hole by thousandths of an inch. Use smaller digits for thin liquids and larger digits for thicker liquids.
Spray (Get Your Technique Right!)
Turn your pump on the “Spray” position. Practice on a piece of cardboard or spare wood first. Adjust the air pressure as needed.
It is important that you move the gun parallel to the surface you are spraying paint. Do not spray in an arc pattern.
In addition, keep your gun perpendicular to the surface. Try and maintain a consistent 10-12 inch distance away from the surface. This is important because your distance affects how much paint you apply to the surface.
If you move fast, you will prevent runs. Keep in mind that using several thin coats is better than applying thick paints. Try to overlap your strokes by 30 to 50 percent.
How to Use an HVLP Sprayer Outdoors
HVLP spray guns use high-volume and low-pressure. With high volume and low pressure, they are best for detail work and automotive projects.
Wagner is one of the top brands when looking for an HVLP spray gun.
Read about how to use a Wagner paint sprayer here.
Here are some simple steps to follow when learning how to use an HVLP sprayer.
Mix Materials As Instructed
Most materials will need to be mixed according to the manufacturer’s instructions.
Prepare Your Cup
Fill the designated paint cup or paint reservoir with materials and leave some room at the top. Never overfill your cup and make sure the lid is securely attached.
Turn the fluid adjusting knob clockwise. This prevents fluid needle movement. Then, turn the spreader valve adjusting knob counterclockwise to ensure it is fully open.
If your finish appears dry, reduce the airflow by reducing air pressure. If the finish appears wet, reduce the fluid flow by adjusting the appropriate knobs. Likewise, you can adjust the spray pattern size and inlet pressures.
Hold your sprayer perpendicular to the surface. If you tilt or arc the sprayer, you’ll end up with an uneven coating.
Spray approximately six to eight feet from the surface. Begin spraying the edges and then overlap the strokes with a minimum of 75%. Keep moving your gun at constant speeds.
How to Use a Spray Gun With an Air Compressor Outside
If you have an air compressor, you don’t need to purchase an HVLP system but could just use a Spray Gun.
Air compressor is more cost effective than purchasing an entire system, but you’ll need your air compressor with you wherever you are doing exterior paint job.
Here are some simple steps to follow when learning how to use a Spraying Gun with an air Compressor while doing exterior paint project.
Prepare the Air Compressor
Turn on your compressor and set the pressure to 90 PSI. You can then adjust the pressure at the gun itself.
Attach the Gun
Secure your spray gun onto the compressor air hose. Place the appropriate materials into you canister as recommended by the manufacturer. Secure the canister to the gun.
Practice spraying on a spare piece of wood so you can make the adjustments needed. Make sure you are using the proper fan spray for your project.
Hold your gun six to eight inches from the surface. Make sure it remains perpendicular at all times. Move the gun horizontally and start painting at the top. Slowly work your way down to minimize running.
Advantages Of Using Paint Sprayers
Paint Sprayers are ideal for a multitude of projects. One of the main reason people use them is to prime or paint new, large interior walls or spaces.
This project goes faster than rolling alone. This is also valuable when working with new construction because the flooring and ceiling won’t be an issue.
When exterior painting of a home that has a clear perimeter, airless sprayers will out-perform painting by hand.
If you don’t have a clear perimeter but have mature landscaping, sunrooms, playsets and other items in the yard, you can still use a paint sprayer, but prep time will be slightly longer.
If you are painting areas that have detail work or texture, use a paint sprayer, which is a great tool. It makes short work of projects like crown molding or popcorn ceilings.
There are sometimes when use an airless paint sprayer won’t be ideal. These include:
Overall, spray paint will generally save you time in comparison to painting with a roller and paint brush. If you are working on a large project, it can also save money over hiring a professional to complete the assignment.
Consider Using These Paint Sprayer Brands
When it comes spray paint with paint sprayers, you not only have to choose the type of sprayer but the brand you want as well. There are dozens of paint sprayer manufacturers out there, and each one has good points and bad points. The problem is that most of them have more bad points than good.
For that reason, you want to stick to a well-known, trusted brand that will stand behind their product. You want a company you know is going to be there tomorrow to help you is something goes wrong, or you need a new part for your older sprayer.
While we aren’t taking anything away from any brand out there, three brand names continue to jump to the top of the list.
Graco has been in the paint supply game for a long time. Their products are tried, tested, and abused, and they continue to perform day in and day out. From the professional, commercial painter to the once-in-a-while DIY homeowner, Graco has products designed for every project and skill level.
Fuji is a name that most professional painters know and trust. Homeowners and DIY experts are also onboard. Fuji makes paint sprayers for every budget and project imaginable and will have what you need when you need it.
One of the biggest draws to Fuji is their paint sprayer accessories, which allow you to expand your exterior paint spraying venture beyond what comes in the box.
Wagner is geared more for the DIYer, though they do have a solid hold on the commercial market as well. If you are looking for a sprayer that won’t see a lot of use, you can save money with Wagner. You won’t lose out on quality, though, and that is why this home-name brand has stuck around for as long as they have.
How Much Should You Spend?
Depending on your budget, there is a paint sprayer for you. You can find budget models that cost less than $100, but these will generally be all-in-one styles that don’t offer accessories or extras. There are also commercial-grade sprayer systems than can top over $2000.

Which Paints Work Well with Sprayers?
When deciding on a proper paint sprayer, you are going to want to make sure it will work with the materials you are using.
Most paint sprayers are versatile and can be used with a multitude of materials including stains, paints, lacquers and primers.
Make sure that you also refer to the user guide of your sprayer to ensure that you are applying proper materials. Most airless sprayers can be used with water-based exterior and interior materials.
In addition, most sprayers are capable of applying oil-based exterior and interior paints.
Not all sprayers will apply paint solvent-based flammable materials. These include primers, shellacs, lacquers and sealers. Refer to the specific sprayer to determine if you can use it for these items.
There are also special materials such as undercoating and sealers that will require a specific model of sprayer. Keep in mind when using thicker materials; you may need a larger spray tip to accomplish the paint job.
You should also cover all furniture, flooring, and any other material you don't want to use an exterior paint to ruin with drop cloths or plastic sheeting.
Clean Up, Maintenance & Storage
Cleaning after use a paint sprayer is a necessary evil that will require your tie, devotion, and attention. You will need to clean your entire unit after every use. This also means that you can't leave paint in the sprayer for very long or it will need to be cleaned.
Paint cures quickly and can form deposits in your sprayer system. You should always have a waste bucket, water, rags, drop cloths and mineral spirits on hand. Cleaning with warm water and a mild soap will take care of most paints.
However, when you apply paint which are oil-based paints, you will need to use mineral spirits to clean.
Cleaning an airless sprayer will require you to spray solvent and discharge fresh cleaning solution through the sprayer to clean out the internal tubes, suction hoses, and inner workings of the guns.
After that, you will disassemble the gun, tip, paint strainer, air caps, nozzles, rods, and paint cups to hand wash and scrub. Some models will require you to oil seals and o-rings, and some will need throat seal liquid added before the next use.
After a thorough cleaning, you should check all the parts and perform routine maintenance on the device. This can be as simple as putting in a new filter and spray tip or replacing tubing and suction hoses if they begin to wear out.
Medium tips are the most commonly used because they are the best choice for oil-based and latex paint.
After inspection, maintenance, and cleaning, you can store your machine. Always paint stores in a cool, dry place away from direct sunlight, debris, and other hazards. Covering your sprayers can help keep them free of dust and dirt, and all sprayers should be stored in an upright position.
What to wear when painting exterior walls?
Though HVLP paint sprayers produce less overspray than airless sprayers, atomized paint can travel, and could possibly get into your nose and eyes. Using a tip with a smaller orifice and spray fan width reduces overspray and eliminates the chances of damaging anything beyond the spray area.
Protect yourself by wearing proper protection before painting door trim, interior or exterior walls. We recommend: Respiratory face mask Safety goggles/ glasses, Old clothing that can be sprayed with paint, Old shoes that can be sprayed, Old hat to protect your head from paint.
Now that you know how to use your new paint sprayer, it is time to get the paint job done.
Remember to always follow the manufacturer’s instructions found in the owner’s manual.
Complete all your household paint jobs with ease and spend more time doing the things you love.
