Installing shrink wrap on a scaffolding needs a heat gun—a tool that must be used with caution. There are a few things to keep in mind to avoid these common shrink wrap issues, many of which come down to proper heat gun use. This guide covers the basics you need to know, whether you’re in training or doing it on-site for the first time.
Minimum and Maximum Temperature Limit
The minimum temperature is around 100°C (212°F), while the maximum is approximately 500°C (932°F). These values depend on the type and thickness of the shrink wrap. We recommend checking the manufacturer’s guidelines to determine the ideal temperature for your specific application.
Now, why is there a limit, and why should it be followed?
If the heat is too low, the shrink wrap may not contract at all. Even if it does, you could end up with wrinkles or loose areas. Excessive heat, in contrast, can cause over-shrinking, resulting in tears or holes. It can also damage the surface being wrapped or even create a fire hazard.
Double Check the Shrink Wrap Heat Gun’s Parts
Heat guns come with a few parts that need to be in good condition for safe and effective use. These include extension, hose, regulator, and liquid propane (LP) gas tank.
The extension is attached to the gun to direct the heat exactly where you need it. Avoid getting it damaged or clogged so it won’t disrupt the heat flow and cause poor results. The hose connects the gun to the gas supply. See to it that there are no leaks, as these can pose a safety risk or even cause a fire.
The regulator controls the gas pressure from the tank to the heat gun. If it’s faulty, it can cause problems, so get it checked and fixed if needed. The LP gas tank is what generates the heat for the gun. Always inspect it before, during, and after use to reduce the risk of leaks, explosions, or running out of fuel.
Some heat guns don’t use LP; instead, they’re powered by electricity. They’re often considered safer because there’s no risk of gas leaks. Even so, regular checks are still important. Make sure the switch is working and always unplug the heat gun when it’s not in use.
Wear Safety Glovesand Eye Protection
Using a heat gun can be risky, even with training. For one, it gets really hot and can cause burns. That said, a pair of scaffold gloves is a must to protect your hands from touching hot surfaces or heated air.
Eye protection, like these Wrap-around Safety Glasses, is just as important. They’ll cover your eyes from any hot air or bits of debris that might get blasted off during the installation. It’s better to be safe than sorry!
Shrink Wrap Heat Gun Use and Film Installation Training
This is especially recommended if you’re an employer looking to deliver excellent results and satisfy your clients. It gives assurance that the job is done safely, efficiently, and at a professional level. Providing your team with training also cuts down on mistakes, saving you time and money in the long run. Even better, it helps build trust with your clients and maintain a good reputation.
