Polyurea Spray Rig Builder
Spray Foam Rig Builder
Tell us what you spray and at what output. Our team can match a gun, mix chamber and rig to your work, with training.
The spray gun is where polyurea and spray foam are actually made. The A and B sides arrive hot and under pressure, collide in a mix chamber the size of a pencil lead, and leave the tip already reacting. A worn chamber, clogged screen or wrong tip shows up instantly as a bad pattern or off-ratio material. This guide explains the main gun types, how to size the mix chamber and how to keep a gun spraying clean.
A polyurea spray gun is a plural-component impingement-mix gun: the A (isocyanate) and B (resin) streams collide at high pressure inside a small mix chamber and exit through the tip already mixed. Air purge guns blow the chamber clean with air when you release the trigger; mechanical purge guns push the leftover material out with a valving rod. Choose the mix chamber and tip for the output and pattern you need, and keep screens, chambers and seals clean every day.
A and B enter separately through check valves and fine screens that stop debris.
Small orifices aim the streams at each other so they collide and mix completely.
The tip shapes the spray fan or round pattern for the job.
Air or a mechanical rod clears mixed material out when you stop spraying.
Opens and closes both sides together so the ratio holds on every trigger pull.
Gun grease protects seals and keeps material from building up.
Mix chamber size controls flow. A small chamber gives a lower output and finer pattern for thin coatings and detail work; a larger chamber pushes more material for big foam and polyurea jobs. The proportioner must be able to hold pressure at the chamber size you choose, and the tip sets the pattern width.
Detail work, edges and thin-mil coatings.
Most bedliners, floors and general polyurea work.
High-output foam and big polyurea areas. Needs a machine with output to match.
Flat fans for coatings and even films; round patterns for foam and some detail.
Grease the gun front and seals at every shutdown to keep material from curing inside.
Clean the A and B screens; a clogged side is the fastest route to off-ratio material.
Look for build-up or wear in the orifices and replace worn chambers.
A lopsided, tailing or spitting pattern means something is clogged or worn.
Keep the safety lock on and the gun capped when not spraying.
Guns are simple to pull and hard to master. ArmorThane trains applicators on equipment setup, gun care, spray technique and troubleshooting, and builds complete rigs with the gun, proportioner and hose matched together. See our polyurea spray guide, spray foam proportioner guide and spray foam rigs.
ArmorThane builds plural-component rigs with the gun, hose and proportioner matched, and trains your crew to spray and maintain them.
Contractors: become an ArmorThane applicator
Polyurea is sprayed with a plural-component impingement-mix gun fed by a heated proportioner. Air purge and mechanical purge guns are both used.
Not fast-set spray polyurea. It gels in seconds, so it must be mixed at the gun by a plural-component system.
Air purge guns blow mixed material out of the chamber with air. Mechanical purge guns push it out with a rod. Both stop the mix from curing inside the gun.
Match it to the output and pattern you need and to what your proportioner can supply at spray pressure. Smaller for detail, larger for production.
Usually a partly clogged screen or chamber, low pressure on one side, or worn parts. Stop spraying and check screens, pressures and the chamber.
Contractors get equipment, coatings and training from one source, with no franchise fee and no royalties. Owners can find a certified applicator near them.
ArmorThane has built a strong reputation over the past 30 years for producing high-quality, durable protective coatings.
