Comparison of Magnum Painter Plus with other Graco airless models

I’ve been using three different airless paint sprayers for quite some time now, and I thought it would be helpful to compare them in different situations. The models I’ll compare are the Magnum Painter Plus, Graco X5, and Graco X7. These sprayers are commonly used by professionals and DIY painters. So, let’s compare their features and determine which one is the most suitable fit for each situation.

Graco Magnum Project Painter Plus Airless Paint Sprayer Summary

  • Recommended Gallons per Year: 50
  • Pressure Range: 0 – 2800 psi
  • Max. Tip Size: 0.015
  • Max. Hose Length: 50 ft

The Magnum Painter Plus is a smaller and more lightweight model compared to the Graco X5 and X7. It is suitable for smaller-scale projects and occasional use. If you have a moderate painting workload, such as painting a single room or small exterior surfaces, this model can handle the job effectively.


  • The RAC IV 515 Switch Tip ensures smooth and efficient spraying.
  • The floor-standing pump provides stability during use.
  • The 25-foot hose offers good reach for various painting projects.
  • Ideal for beginners in airless spraying, making it user-friendly.
  • The suction hose eliminates the need for frequent refilling.


  • High power setting may result in significant overspray, requiring careful control.
  • May require thicker stains to achieve optimal performance with this unit.
  • Weighs 15 lbs, which might be considered relatively heavy for some users.

Graco X5 vs Project Painter Plus

  • Recommended Gallons per Year: 125
  • Pressure Range: 0 – 3000 psi
  • Max. Tip Size: 0.015
  • Max. Hose Length: 75 ft

The Graco X5 is a versatile airless paint sprayer that offers a higher recommended gallons per year capacity than the Magnum Painter Plus. It can handle larger-scale projects and is suitable for homeowners and DIY enthusiasts with more frequent painting needs. With its higher pressure range, it provides more power and can handle thicker paints and coatings.

Graco Magnum X7 vs Project Painter Plus

  • Recommended Gallons per Year: 125
  • Pressure Range: 0 – 3000 psi
  • Max. Tip Size: 0.017
  • Max. Hose Length: 100 ft

The Graco X7 is similar to the X5 in terms of recommended gallons per year and pressure range. However, it has a slightly larger max tip size of 0.017 and a longer hose length of 100 ft. This makes it better suited for larger projects or areas that require a longer reach, such as multi-story buildings or extensive exterior painting jobs.

In summary, if you have a smaller painting workload and occasional use, the Magnum Painter Plus should be sufficient. For more frequent painting needs and moderate-sized projects, the Graco X5 would be a suitable choice. If you have larger-scale projects or need a longer hose length, the Graco X7 would be the best option. Consider your specific painting requirements and the scale of your projects to determine which model would best meet your needs.

My Experience with Magnum Project Painter Plus

I started with HomeRight Super Finish Max for a flawless finish for kitchen cabinet doors. It did well with the primer, but left annoying paint bubbles when I sprayed on the actual paint. Then I bought and tested the Graco Painter Plus, a mighty beast that exceeded my needs. I used Benjamin Moore advance paint, which flowed seamlessly through it, resulting in flawless doors in just a few seconds as shown in the image below.

There was overspray and cleanup, but the convenience of leaving paint overnight and the minimal mist in the air made it all worthwhile.

Best material to use in your graco magnum project painter plus

The Magnum Project Painter Plus is a paint sprayer designed for handling large painting tasks with both water-based and oil-based paints and stains. In my opinion, this graco sprayer works better with water-soluble paints than oil-based paints.

If you prefer oil-based paints, you should thin them to the right consistency using mineral spirits to achieve similar results. However, it’s important to note that the sprayer may clog if you use materials with textures in them. It is not suitable for spraying lacquers or enamels.

When it comes to paint, latex paint works best with this sprayer. It can also do a satisfactory job with certain stains, but the stain needs a thicker viscosity. On the other hand, it performs excellently when spraying acrylic paint.

Acrylic and latex paints are particularly well-suited to airless painting, where paint is sprayed without compressed air. This method allows faster drying and reduces overspray. However, if you use an air-assisted machine, where the paint is sprayed through compressed air, it’s important to properly dilute the paint to avoid nozzle clogging.

Graco Project Painter Plus Performance

The powerful pump and adjustable pressure control of the Graco Magnum Project Painter ensure a smooth and consistent spray pattern, resulting in professional-quality finishes. Whether you’re painting walls, fences, decks, or cabinets, this sprayer delivers exceptional coverage and effortlessly handles a wide range of paints and stains.

With its stainless-steel piston pump designed for long hours of continuous use, it proves reliable for even the most extensive projects. Despite its compact size, it rivals larger consumer sprayers in specifications, making it a cost-effective choice. Though it may require some practice to master, the adjustable pressure dial and recommended extension rod provide enhanced control and comfortable spraying.

By employing careful technique and plastic and tarps, you can prevent unwanted overspray. The Graco Magnum Project Painter Plus is an impressive performer that ensures remarkable results every time.

Graco Magnum 257025 Portability

Unlike some other models, it doesn’t come with a wheeled cart. This means you’ll have to lift the entire unit, along with the paint-filled bucket, hose, and gun, by yourself. However, by purchasing a longer hose, such as a 50-foot one, you can cover a wider area without moving the sprayer unit frequently.

Graco sells longer hoses, but remember, this sprayer can only handle up to 50 feet. If you’ve got a larger project, like painting a multi-story house, you might want to consider a more powerful sprayer like Graco X5 or X7 models.

But hey, the sprayer has a saving grace. It’s got a robust handle built into the upper casing, which is handy when you need to transport it. So, while it may not be the most portable option out there, they added a convenient handle. This is for those times when you have to move it around.

Graco Magnum Project Painter Plus Tips

Graco Magnum Project Painter Plus Tip

Your Graco Magnum 257025 Project Painter Plus Paint Sprayer includes a 515 True Airless spray tip. This is just one of the 16 available True Airless tip sizes.

When using your Magnum sprayer, it’s important to choose the right spray tip size for the material you’re working with. For thinner substances like stains and enamels, it’s best to use a smaller tip size. This allows for more control and a smoother application.

On the other hand, when working with thicker materials such as exterior, latex, or oil-based paints, opt for larger tip sizes. They allow for a higher flow rate, ensuring efficient coverage.

Remember, the size of the hole in the spray tip determines how quickly the material leaves the gun. So, a larger hole size results in a faster spray. For instance, a 313 tip will spray faster than a 311 tip.

Graco Project Painter Plus Cleaning

The cleanup process for the Project Painter Plus is an important aspect to consider, especially if you are using oil-based paints or stains. It involves running fresh mineral spirits through the equipment, so it’s crucial to ensure you have an ample supply and a proper plan for waste disposal.

You have two options for managing the waste: you can either reuse the mineral spirits by allowing them to settle and straining them, or you can contact your local waste facility to learn the appropriate method for disposal.

However, if you are using water-based paints, the cleanup becomes easier and more straightforward. All you need to do is connect a standard garden hose to the intake valve of the equipment and flush the excess paint into a bucket or slop sink. This eliminates the need for mineral spirits and simplifies the cleanup process.

It’s worth noting that when storing the Project Painter Plus for an extended period, particularly for cabinet or furniture spraying, it is recommended by Graco to fill the unit with their proprietary Pump Armor fluid. This precaution helps to protect the equipment and ensure its proper functioning when you need to use it again after a prolonged period of storage.

Graco Magnum Project Painter Plus Replacement parts

Magnum replacement kits include essential components to repair or replace damaged parts. This allows uninterrupted spray performance and extends Magnum equipment lifespan.


In summary, the Graco Painter Plus is a highly capable and user-friendly airless paint sprayer. It offers excellent performance, versatility, and ease of use, making it suitable for a wide range of indoor and outdoor painting projects. So, invest in this versatile sprayer, and you’ll be well-equipped to handle any painting task that comes your way. Thank you for reading my Graco Magnum Project Painter Plus Review.
