Choosing a Spray Gun Based on Your Project Needs

A vital part of Polyurea application is choosing the right gun. Within this article, we will review the top seven types of Polyurea and Polyurethane applications, which gun is best, and why you should choose them for your next project.

The technologies in the spray guns we will be discussing combine rapid trigger response, superior atomization, and quick-change spray pattern size to output combination allowing for longer duration for spraying.


Roof & Wall Insulation

Practically any spray gun will work great for roofing and wall insulation. The Graco Fusion line is a popular choice, along with the PMC Air Purge line. Click here for more options.

Air Sealing Attics and Rim Joists

Applying open-cell foam or closed-cell foam in attics and walls, having a durable gun that is lightweight and simple to handle is crucial. The Fusion CS and Fusion, Mechanical Purge guns are ideal for sealing wear tight rim joists. Click here to learn more about these guns.




Roof Coatings

Given the variety of roof coatings needing multiple materials applied, including a closed-cell foam and coatings – the Fusion Mechanical Purge, GX-7, and Problem P2 are all ideal for high output spray polyurea applications. Learn more about our roofing system guns.




Pipe & Tank Coating

For projects requiring protection of storage vessels, including; steel and concrete tanks, pipe linings, reactors, rail tank cars, truck tankers, potable water tanks, bulk dry-storage tanks, and more – the best-fitted guns are Graco’s Fusion Air Purge, Fusion Mechanical Purge, and GX-7. Alternatively, PMC’s AP-3 and PX-7 Mechanical Pour Gun are ideal as well. Learn what to use for Pipe & Tank Coatings.




Secondary Containment Spill Prevention

A secondary containment system provides an essential line of defense in the event of a failure of the primary containment, such as a bulk storage container, a mobile or portable container, piping, or oil-filled equipment. Graco Fusion Air Purge and Mechanical Purge and PMC AP3 or PX-7 Mechanical Purge are ideal for these types of projects. Click here for more options.



Spray-On Bedliners

When applying the material to truck beds, a variety of entry-level and industrial-use equipment are available—starting with Graco Fusion Air Purge, Fusion Mechanical Purge, GX-7 – as well as PMC’s AP3 and PX-7 Mechanical Purge. Learn more about these guns.





Waterproofing

When working on waterproofing projects, efficiency is key. Graco Fusion Air Purge, Mechanical Purge, and GX7 and PMC’s AP3 and PX-7 Mechanical Purge work exceptionally well for waterproofing projects. Learn more about these guns.





Types of Spray Guns



Air Purge Spray Guns

The Graco and PMC AP series spray guns present the operator with easy-to-operate and maintain spray guns that can be utilized in various applications. These air purge guns provide the operator with simple output settings by simply removing and replacing the appropriate size chamber right from the front of the gun with no gun disassembly needed.

The design of these guns enables the applicator to leave the gun connected to the hose set at the end of the day by pumping a small amount of grease into the mixing section.

Some of these gun’s features combine a revolutionary 360-degree rotational head allowing hoses to be connected to the top or the bottom of the gun. This quick-change mixing chamber allows removal from the front of the gun without disassembling two separate air connection locations: one-piece machined mixing chambers and a new air cap designed to preserve the mixing chamber tip.

Mechanical Purge Spray Guns




Graco Mechanical Purge Spray Gun provides the applicator a spray gun designed to reduce operator fatigue and facilitate utilization control. With this aim, a new ergonomic gun handle has been produced and placed at the center of balance to balance weight distribution and provide enhanced stability during the application.

All models include a tool kit with the necessary tools for proper adjustment and support of the gun. Some of this gun’s features combine superior mixing, while the engineering cleaning minimizes reacted substance inside the mixing chamber. Easy spray pattern tip turns out without changing the mixing chamber and a powerful air cylinder to expedite the rapid valving reaction.





Graco Fusion Spray Gun

The Graco Fusion Spray Gun features an easy air-blast tip cleaning to help reduce build-up and tip clogging. The spray gun’s long-lasting side seals mean less downtime for maintenance, and applicators experience quick-release fluid housing, allowing you to change the mixing chambers without simply using tools.

If you need to remove the front cap, it can be quickly removed or replaced by the hand-tightened front cap – no tools are required to clean the spray gun, maintaining the seal and mix chamber.
