Getting Your IR Lamp Layout Right in Custom Paint Booths
When we’re building custom heating walls for paint booths, the biggest headache is always the cars themselves. I mean, think about it. A tiny coupe and a massive SUV don’t soak up heat the same way. If you just space your infrared lamps evenly—like a ladder—you’re asking for trouble. You’ll end up with cold spots on the roof and a lower chassis that’s practically frying. Not a good look. Mapping the heat Here is how we actually handle it. We look at the shape of the vehicle and place the lamps where they’re actually needed. We bunch the lamps closer together in the middle to really hit those doors and fenders. Then, we leave a bit more breathing room at the very top and bottom. Why? Because that’s how you stop the paint from flashing or bubbling. You also have to keep an eye on the distance between the lamp and the car. It’s a balancing act. Shortwave IR digs deep into the primer, while medium-wave is your best bet for the clear coat. We usually mix the two or tweak the wattage so the heat actually hits the metal instead of just warming up the air in the room. The heavy lifting We mount everything in reinforced aluminum frames. It’s the only way to keep the wiring from melting under all that heat. Most of our builds use high-wattage quartz tubes. Just a heads-up: make sure your electrical panel can handle the initial surge when you flip the switch. If it can’t, you’ll be tripping breakers all day. And keep an eye on your fans. High-wattage tubes put a lot of pressure on your cooling system. If your airflow is off, the heat just pools at the ceiling, and your curing becomes a total mess. The trade-off Here’s the catch. When you customize a wall for a specific shape, it’s not “one size fits all” anymore. If your shop switches from painting sedans to trucks, you can’t just press a button. You’ll have to get in there, slide the brackets around, or swap out the tubes for something with more kick. It’s a bit of a pain, sure. But it’s the only way to get that perfect, professional cure every single time.
