In this blog post, we’ll guide you through the steps to prime your Graco airless paint sprayer, to ensure you get the best results for your paint job.
What is priming and why is it important?
If you’re wondering how to prime a Graco airless paint sprayer, it’s important to first understand what priming is and why it’s necessary. Priming is the process of preparing the airless paint sprayer for use by filling the pump with paint and expelling any air from the system. This ensures an even flow of paint and prevents spitting or clogging during the painting process.
Without proper priming, the paint sprayer may not work correctly and could lead to frustrating and time-consuming issues. To prime a Graco airless paint sprayer, simply fill the pump with paint and follow the manufacturer’s instructions for expelling air. By taking the time to prime your paint sprayer correctly, you’ll be able to achieve a flawless finish and save yourself a headache down the road.
Definition of priming
Priming, simply put, is the process of activating certain concepts or ideas in someone’s mind to influence their subsequent thoughts or actions. It’s important because it can affect our decision-making and behavior without us even realizing it. Think about how advertisements use certain words, images, or sounds to make us more likely to buy a particular product.
That’s priming in action. It can also impact our perceptions of individuals or groups, which is why it’s essential to be aware of potential biases or stereotyping that may result from priming. By understanding the power of priming, we can be more mindful of the messages we consume and the ways in which they may shape our thinking.
Importance of priming
Priming is a psychological phenomenon that describes the implicit influence of our environment on our thoughts and behaviors. It refers to the activation of certain concepts or ideas in our mind, which then affect our perception and interpretation of subsequent stimuli. The importance of priming lies in its ability to shape our attitudes, beliefs, and actions without us even realizing it.
For example, exposure to words related to aging can cause us to walk more slowly, while exposure to words related to aggression can make us more likely to choose violent solutions to problems. By understanding and utilizing priming, we can influence people to make more informed decisions, adopt healthier habits, and even reduce prejudice and discrimination. Whether we are marketers, educators, or policymakers, priming offers a powerful tool for shaping human behavior and guiding positive change.

Step 1: Prepare the equipment
If you’re planning to use a Graco airless paint sprayer, it’s essential to follow a few steps to prime the machine correctly. Before starting, it’s important to prepare the equipment for the task at hand. First, ensure that the sprayer is clean and free of any debris.
You can do this by flushing out any old paint or residue with water or a cleaning solution. Next, check that all of the parts are functioning correctly, including the hose, nozzle, and gun. If anything is damaged or broken, it needs to be replaced before using the sprayer.
Finally, make sure you have the right type of paint and enough of it for your project. Once these steps are complete, you’re ready to begin the priming process and start painting with ease. Just remember to take the necessary precautions to protect yourself and your surrounding area, such as wearing safety gear and covering nearby objects to prevent splatters.
By prepping your Graco airless paint sprayer beforehand, you can ensure a successful and stress-free painting experience.
Step 2: Fill the pump with paint
When it comes to using a Graco airless paint sprayer, one of the essential steps is priming the machine. This process involves filling the pump with paint to ensure that everything is running smoothly before you begin painting. To fill the pump, you’ll first need to attach a clean paint container to the sprayer’s suction hose.
Then, remove the prime spray valve and filter from the machine and ensure that they are clean and free from any debris. Replace these components and ensure they are secured tightly. Next, turn on the sprayer and set the pressure to its lowest point.
Slowly begin to pour the paint into the container while keeping an eye on the pressure gauge. If the pressure begins to rise too quickly, turn off the machine and adjust the pressure as necessary. Once the paint is in the container, replace the prime spray valve, making sure it is secure.
Finally, engage the trigger and let the machine run until the paint is flowing smoothly and without any splatters or drips. By following these steps, you’ll ensure that your Graco airless paint sprayer is primed and ready to deliver a flawless finish to your painting projects.
Step 3: Attach the spray gun
One of the essential steps in priming a Graco airless paint sprayer is attaching the spray gun. After installing the prime spray valve and attaching the suction hose, you need to attach the spray gun to the paint hose. To do that, you need to align the black or yellow tabs on the spray gun with those on the paint hose.
Push the tabs in, and then twist the gun in place to lock it into position. Ensure that the spray gun’s filter and guard are attached correctly, then you’re good to go. With the spray gun attached, you can now start the priming process.
The spray gun is where the paint will come out, making it a crucial component in the airless paint spraying process. Without the spray gun, the paint cannot be sprayed onto the surface. Therefore, it is essential to ensure that the spray gun is correctly attached to avoid any leaks or damage.
Step 4: Turn on the sprayer and adjust the pressure
Now that you have your Graco airless paint sprayer primed, it’s time to get ready to use it by adjusting the pressure. To do this, turn on the sprayer and adjust the pressure accordingly. The pressure adjustment knob can usually be found on the back of the sprayer, and you’ll want to adjust it to match the type of paint you’re using and the surface you’ll be painting.
For example, if you’re using thin paint on a smooth surface, you’ll want to use a lower pressure setting, whereas thicker paint on a rough surface will require a higher pressure setting. It’s important to get this right, as too much pressure can cause overspray, while too little pressure can result in an uneven finish. Take the time to experiment with different pressure settings until you find the right one for your specific project.
With the pressure adjusted, you’re now ready to start spraying!
Step 5: Open the prime valve and begin priming

To do so, you need to open the prime valve. This valve allows paint to flow from the hopper to the spray gun.
To open the prime valve, hold your spray gun down and turn the prime knob counterclockwise. Once you do this, you will hear a hissing sound. This sound indicates that the valve is open, and paint is flowing through the sprayer.
Now, you need to keep the sprayer close to your paint can and allow the Graco Airless Paint Sprayer to prime itself. This process involves pushing the paint through the hose and clearing the air out. You will notice paint coming out of the nozzle that might be mixed with air.
Once the prime valve releases clear fluid without air, you can stop priming the machine and get ready to paint your surface.
Tips and Tricks for Successful Priming
If you want to achieve a flawless finish when painting with Graco airless paint sprayers, then it’s essential to know how to prime the device. The process of priming involves filling the sprayer with paint and removing any air pockets to ensure smooth and consistent application. To do this, start by attaching the required spray tip and hose to the unit, followed by pouring the paint into the spray gun’s cup.
Next, hold the sprayer over a bucket or waste container and flush the system by spraying water through it until clear. After this, switch the unit to prime mode and allow the paint to flow through the tubing until it reaches the gun. Finally, adjust the pressure and test spray on a piece of scrap material to ensure everything works correctly.
By following these simple steps, you’ll be able to prime your Graco airless paint sprayer like a pro and achieve stunning results every time.
Tip 1: Use the correct type of paint
When it comes to achieving a successful priming job, using the correct type of paint is crucial. You don’t want to be stuck with flaky or uneven paint, and that’s where choosing the right type comes in. For example, if you’re priming a bare metal surface, opt for a rust-inhibiting primer to prevent any rusting from occurring.
Wood surfaces, on the other hand, should be primed with a high-quality wood primer that will seal the pores and ensure smooth paint application. Remember, not all primers are created equal, and choosing the wrong one can lead to a failed project. So take the time to research and choose the right type of primer for the surface you’re working with, it will save you time, money and frustration in the long run.
Tip 2: Check the filter regularly
One important tip to ensure successful priming of your pump is to regularly check the filter. All pumps have a filter that traps debris and prevents it from entering the pump. Over time, the filter can become clogged and decrease the efficiency of your pump.
Frequently checking and cleaning the filter will help keep your pump running smoothly and extend its lifespan. A clogged filter can cause your pump to suck in air, which can hinder the priming process and cause it to lose prime. This can be an expensive and frustrating problem to fix.
By simply checking the filter regularly, you can avoid this issue and keep your pump operating at its best. Don’t forget to replace the filter periodically as well to ensure optimal performance. So take a few minutes to check your filter and give your pump the attention it deserves.
Tip 3: Maintain the correct pressure level
When it comes to successful priming, maintaining the correct pressure level is crucial. This means keeping an eye on your pressure gauge and making adjustments as needed throughout the priming process. If the pressure is too high, you risk damaging the equipment and potentially causing injury.
On the flip side, if the pressure is too low, the primer may not flow evenly or at all, resulting in an inadequate finish. It’s essential to follow the manufacturer’s recommendations for the correct pressure range, as this can vary depending on the type of primer you’re using and the equipment you’re operating. By taking the time to monitor and adjust your pressure level, you’ll ensure a smooth and successful priming experience.
So, don’t underestimate the importance of pressure control – it could make all the difference in achieving the perfect finish for your project.
Conclusion
In conclusion, priming a Graco airless paint sprayer is a crucial step in achieving a smooth and even finish on any painting project. It’s like warming up before a workout – you won’t see the best results without taking the time to properly prime your sprayer. So, grab your paint, follow the manufacturer’s instructions, and get ready to spray with confidence! Remember, a well-primed sprayer is the key to a picture-perfect paint job.
Happy painting!”
