9 Best Spray Gun For Polyurethane 2025 in the United States

The AWF PRO Foam Gun - AWF 1850 is a solid choice for both contractors and DIY enthusiasts looking for an effective tool to apply polyurethane foam. One of its standout features is the PTFE non-stick coating, which greatly aids in cleanup and prevents foam buildup, making it easier to maintain. The 40-inch long barrel is designed for extended reach, helping users access hard-to-reach areas without straining. Its swivel tip further enhances maneuverability in tight spaces, which is a definite plus for detailed work.

One of the strengths of this foam gun is its compatibility with various Great Stuff Pro Cans, allowing for seamless use with popular foam products. This makes it a great fit for users who frequently work with these specific materials.

The ease of use is commendable; simply attach the can, and you’re ready to spray. The adjustable control knob allows for precise bead size changes, catering to different project needs. However, users should be aware that if there’s leftover foam in the can, they will need to run a cleaner can through the gun to prevent clogging. Durability appears to be a strong point, with many users noting that it withstands regular use without breaking down. However, as with any tool, care and proper cleaning will go a long way in extending its lifespan. With these factors in mind, the AWF PRO Foam Gun is a reliable option for applying polyurethane foam, particularly for users who prioritize ease of cleaning and reach.

The TCP Global Brand HVLP Spray Gun Set offers a versatile and comprehensive solution for those looking to apply a variety of coatings, including polyurethane.

This makes it highly adaptable for different projects, from automotive painting to household touch-ups.

The inclusion of an air regulator, moisture filter, and a cleaning kit enhances its value, offering users the tools needed for both precise application and maintenance. The stainless steel build ensures durability and longevity, while the low-pressure, high-volume design helps in achieving professional finish results with minimal overspray.

Some users may find the initial setup and adjustment of pressure settings a bit challenging without prior experience. The one-year warranty provides some peace of mind, though it might be on the shorter side compared to some competitors. This spray gun set is particularly beneficial for DIY enthusiasts and semi-professional users who need a reliable and flexible tool for various painting tasks.

Additionally, the gun supports 360-degree spraying, providing consistent performance even when used upside down. Users will appreciate the ease of achieving like-new performance with replaceable atomizing heads, ensuring the spray gun maintains its quality over time. However, the absence of an air compressor and hose coupler in the kit means additional purchases are required to start using the spray gun.

While it boasts a solid build quality, the unit's weight of 2.6 pounds might be slightly cumbersome for extended use. Given its industrial focus, the 3M Accuspray Paint Spray Gun System is best suited for professional painters and serious DIY enthusiasts who need a reliable and efficient tool for detailed and varied painting tasks.
