Why Use a Paint Sprayer?

Best HVLP Paint Gun 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 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 painting the exterior of a home that has a clear perimeter, 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, a paint sprayer is a great tool. It makes short work of projects like crown molding or popcorn ceilings.

There are sometimes when using a paint sprayer won’t be ideal. These include:

  • Painting of areas that have many items requiring masked and covered
  • Painting of areas that have many items requiring masked and covered
  • The need to save money
  • Painting a surface that isn’t completely clean

Overall, spray painting will generally save you time in comparison to painting with a roller and brush. If you are working on a large project, it can also save money over hiring a professional to complete the assignment.

How to Use an Airless Sprayer?

Airless sprayers pump paint at high pressures, oftentimes up to 3000 PSI. The tip is designed to break up the paint evenly into a spray pattern made of small droplets. Some models, such as Graco 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. Read our Best Airless Sprayers Review if you need help finding the right model for your project.

Here are some simple steps to follow when learning how to use an airless sprayer.

  • 1
    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 begins to flow, move it into the paint bucket. Hold the spray gun over the empty bucket and pull the trigger. Continue until the paint begins to flow at a steady stream.
  • 2
    Choose Your Tip Size
    Most spray 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 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.
  • 3
    Turn your pump on the “Spray” position. Practice on a piece of cardboard or spare wood first. Adjust the pressure as needed.
  • 4
    Spray Techniques
    It is important that you move the gun parallel to the surface you are spraying. Do not spray in an arc pattern. In addition, keep your gun perpendicular to the surface. If you move fast, you will prevent runs. Keep in mind that using several thin coats is better than applying a thick one. Try to overlap your strokes by 30 to 50 percent.
  • 5
    Remove Clogs
    If the paint sputters, your tip might be clogged. Twist the tip around 180 degrees and point it at some scrap wood. Squeeze the trigger and try to unclog the tip.

How to Use an HVLP Sprayer?

HVLP spray guns use 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. If you need more help finding the right model, be sure to read our Best HVLP Spray Gun Reviews.

Here are some simple steps to follow when learning how to use an HVLP sprayer.

  • 1
    Mix Materials As Instructed
    Most materials will need to be mixed according to the manufacturer’s instructions.
  • 2
    Prepare Your Cup
    Fill the designated cup with materials and leave some room at the top. Never overfill your cup and make sure the lid is securely attached.
  • 3
    Adjust Gun
    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.
  • 4
    If your finish appears dry, reduce the airflow by reducing pressure. If the finish appears wet, reduce the fluid flow by adjusting the appropriate knobs. Likewise, you can adjust the pattern size and inlet pressures.
  • 5
    Spray Techniques
    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. Start with 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 a Compressor?

If you have an air compressor, you don’t need to purchase an HVLP system but could just use a Spray Gun. These are more cost effective than purchasing an entire system, but you’ll need your compressor with you wherever you paint. For tips on which HVLP spray gun will be best for your needs, read our Best HVLP Spray Gun Reviews.

Here are some simple steps to follow when learning how to use a Spray Gun with a Compressor.

  • 1
    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.
  • 2
    Attach the Gun
    Secure your spray gun onto the compressor hose. Place the appropriate materials into you canister as recommended by the manufacturer. Secure the canister to the gun.
  • 3
    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.
  • 4
    Spray Techniques
    Hold your gun six to eight inches from the surface. Make sure it remains perpendicular at all times.

    Move the gun horizontally and start at the top. Slowly work your way down to minimize running.

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 sprayers can be used with water-based exterior and interior materials. 

In addition, most sprayers are capable of applying oil-based exterior and interior materials.

Not all sprayers will apply 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 task.


Now that you know how to use your new paint sprayer, it is time to get the jobs done. Remember to always follow the manufacturer’s instructions found in the owner’s manual. Complete all your household tasks with ease and spend more time doing the things you love.
