The coatings industry has gone mobile

Your shop goes wherever the work is.

Pull up and spray.

Your rig carries its own power, air, heat and material. No utility hook-ups, no hauling parts back to a shop — just set up, spray and drive home.

One rig. Dozens of markets.

Bedliners in the morning, a roof or a floor in the afternoon. The same proportioner sprays polyurea, polyurethane and spray foam — so one investment opens a lot of doors.

Keep what you earn.

ArmorThane is not a franchise. No franchise fee, no royalty, no marketing fund, no territory quota and no percentage of your gross. Your business is yours.

The rigs

Pick your rig.

Three proven layouts — equipment room forward, spray room aft, so generator heat and noise stay away from your materials and your crew. Every build can be customized to the work you do.

Inside a finished rig

Every piece has a job.

These are real photos from a finished ArmorThane Mobile Coatings Unit. Drag the rail to walk through it — power, air, heat and material, all laid out to run the whole job from the trailer.

Looking into a finished spray rig from the rear ramp — 01 **Walk-in spray room** Spring-assist rear ramp, 36″ side door and an LED work-light wing over the 89 × 84″ rear opening.

Proportioner, drums and transfer pumps inside the rig — 02 **Proportioner, drums & pumps** The heart of the rig: a plural-component proportioner fed by heated drums and 2:1 transfer pumps.

Proportioner control panel — 03 **Proportioner controls** Set temperature and pressure for A and B sides. 3,500 psi hydraulic, heating up to 410 ft of hose.

Diesel generator in the equipment room — 04 **Diesel generator** 3-phase power for the whole rig, with a ducted radiator and exhaust out the front wall.

Air compressor in the equipment room — 05 **Air compressor** Gun purge air, transfer pumps and air tools — all from the equipment room.

Air dryer — 06 **Desiccant air dryer** Two-stage pre-filtration feeds clean, dry air so moisture never reaches your iso.

Heated hose on the wall rack — 07 **Heated hose rack** Hose pays out through a curb-side hatch. Add 50 ft sections as your jobs get bigger.

Electrical disconnects and panel — 08 **Power distribution** Dedicated disconnects and breakers for every system on the rig.

Wall exhaust fan — 09 **Exhaust fan** A wall exhaust fan pulls generator heat out of the equipment room.

Tool chest in the spray room — 10 **Tool chest & workbench** Tool chest, wall cabinets and a pegboard so guns and parts are always within reach.

How a rig gets built

From empty trailer to spray-ready rig.

Every Mobile Coatings Unit is built by ArmorThane in Springfield, Missouri. Scroll through a real build — these photos are from our shop floor.

01/09
Start with a bare shell

Every MCU begins as an empty enclosed trailer — sized to the rig you picked and the truck you tow with.
02/09
Frame, wire & insulate

Closed-cell foam goes into the walls, floor and roof. Conduit, power distribution and the partition wall go in before anything is closed up.
03/09
Set the equipment room

Generator, compressor and air dryer are set forward of the partition, so heat and noise stay away from your spray room.
04/09
Mask everything

Walls, doors and fixtures are masked so the spray room can be lined in one clean, seamless pass.
05/09
Line it with ArmorThane

The spray room floor and lower walls get a seamless ArmorThane polyurea liner — the same coatings you will be selling.
06/09
A room built for overspray

Pull the masking and you have a tough, washable spray room that shrugs off chemicals, drums and boots.
07/09
Plumb the proportioner

Drums, heaters, transfer pumps, proportioner and heated hose are installed, plumbed and wired to run as one system.
08/09
Graphics, test & handoff

The rig gets its ArmorThane Mobile Coatings Unit graphics, systems are run, and it is ready to hook to your truck.
09/09
Train & launch

Hands-on training on real equipment, health & safety certification, then 24/7 tech help by phone once you are spraying.

FAQ

Good questions.

Still wondering about something? Call (417) 831-5090 — a real person picks up.

Do I need coating experience to start?

No. Plenty of ArmorThane owners start brand new. Training covers the equipment, application techniques and health & safety, and ArmorThane technicians are available 24/7 by phone after you launch.

How much does a mobile coating rig cost?

It depends on the rig size, proportioner, hose length and options you choose. Fill out the startup form and an ArmorThane equipment specialist will send rig configurations, pricing and training details, then walk you through them by phone.

Is there a franchise fee or royalty?

No. ArmorThane is not a franchise — there is no franchise fee, no royalty, no marketing fund, no territory quota and no percentage of your gross.

What can I spray with an MCU?

Truck bedliners, RV roofs, trailers, garage and concrete floors, commercial roofing, spray foam insulation, secondary containment, manholes, tanks, marine and farm equipment — polyurea, polyurethane and spray foam all run through the same type of plural-component equipment.

What do I need to tow it?

The 20′ and 24′ rigs are bumper-pull trailers on tandem torsion axles with electric brakes. The 26′ is a 14,000 GVW gooseneck that needs a gooseneck hitch. Your equipment specialist will confirm the right setup for your truck.

Can I customize the layout or equipment?

Yes. Every rig keeps the equipment room forward and the spray room aft, but the proportioner, hose length, guns, storage and options can be built around the work you plan to do.

Do you offer financing?

Ask your equipment specialist — financing options are part of the rig pricing conversation.

Will I get a protected territory?

ArmorThane offers an exclusive, protected territory at no additional cost, based on the population you can service and your equipment capabilities.

What happens after I submit the form?

An ArmorThane equipment specialist reviews what you want to spray, then reaches out with rig options, pricing and training details. Want to talk now? Call (417) 831-5090, Monday–Friday, 8 a.m.–5 p.m. Central.
