Heat guns are a great addition for a DIY’er to possess in their arsenal. Heat guns have a wide array of uses and are most commonly used to strip paint.
They can also be used to dry out damp wood, bend plastic, soften adhesives and shrink wrapping.
Benefits of Using a Heat Gun
There are several benefits to owning a heat gun and having it on standby. As long as you use a variable temperature heat gun, the possibilities of use and benefits are nearly endless.
For starters, heat guns don’t have a flame. Unlike other heat-making tools, you won’t have to worry about starting fires or adjusting flames. Heat guns are also electrically and heat protected. Internal sensors will shut the gun off is it becomes too hot, is used too long, or gets a power surge from the outlet.
Depending on your intended use for the heat gun, the benefits can be enormous. From saving time to making repairs on items you might otherwise throw away. Detailed uses and the benefits for each are listed below.
What Can I Use a Heat Gun For?
There are many uses for a heat gun, but here are the most popular applications.
Taking off paint from furniture or other woodworking items could be a pain unless you have a heat gun. Removing paints without the use of solvents and chemicals is safer and environmentally friendly.
If you are in a hurry to get your painting tasks done, it is possible to use a heat gun to reduce your wait time.
Shrink Wrap Applications
Whether you work with videos or gift baskets, applying shrink wrapping is much easier with a heat gun.
The heat gun will require a special nozzle, but a heat gun makes it easy to weld PVC pipes and floor tiles.
Removing a bumper sticker from a car is easy with a heat gun. Any removing residue can be removed with WD-40 or Goo-Gone.
Thaw Frozen Pipes
Ever turn on the faucet and find that there is no water during the winter months? Apply heat from your heat gun over the frozen area of the pipe and thaw it quickly. Just be careful to do it slowly and make sure your pipes can handle it or you might have a bigger mess.
Restore Automotive Trim
Older cars tend to lack luster in their trim. Take the heat gun to it and restore your black trim to its original shine.
Heat guns are capable of fixing any defective or unlevel candles.
Ever wanted to roast your own coffee? You need temperatures of 750 degrees Fahrenheit which shouldn’t be an issue for most heat guns.
You are basically just shrinking tint film to your window. The heat gun makes the process much smoother.
Have a small, shallow dent that needs to be repaired? Use the heat gun to gently warm the area. Then, apply dry ice to cool the metal and pop out the dent. Do not overheat the metal or the paint will be removed in the process.
Features of the Best Heat Guns
When you are in the market for a new heat gun, here are some of the features you should look for:
Most heat guns feature 1000 to 2000-watts of power. If there are airflow and heat controls on the gun, the more wattage you have, the better.
The main control switch is usually located in front of the pistol grip. This switch gets turned off automatically when the pressure is removed making it safer if the gun gets dropped.
High-quality guns will produce a wide range of temperatures. The larger the range, the more useful the gun is.
This feature is a must-have if you want to properly store the gun.
High-quality guns will offer more than one speed or variable speed which makes the tool more useful.
This stand allows the gun to rest during work and afterward in a safe position. It also allows for hands-free work such as bending a plastic pipe.
Heat guns often come with a variety of nozzles that are used for various purposes. You normally will have to purchase these separately, but it is important to note if your gun will work with the nozzles you desire.

How Does a Heat Gun Work?
A heat gun will always have a source of heat. This is usually produced by a heating element but sometimes consists of a gas flame. There is also a mechanism to move the hot air, usually an electric fan.
Heat guns contain a nozzle which directs the hot air and a power switch to turn it on. Sometimes the heat gun will come with other features such as variously shaped nozzles, ergonomic handle or external stand.
A heat gun will emit temperatures between 100 °C and 550 °C (200-1000 °F), while some can run higher.
Heat Gun Nozzle Types
You will find that there is a wide variety of nozzle types to help you accomplish a myriad of jobs. Here are the most used nozzle types and their general applications.
Heat Gun vs Hair Dryer
Many people think that using a hair dryer is the same as operating a heat gun. While they both produce heat and have the same concept in design, there are some big differences between the two.
First of all, the maximum temperature of most hair dryers is 140 degrees Fahrenheit. To have a hair dryer with higher temperatures than this would burn your skin. The heat coming from the hair dryer isn’t going to be powerful enough for most heat gun applications.
Hair dryers are designed for drying hair. There are times, however, where they might work in a pinch for some applications of a heat gun. If you have a sticker or adhesive that needs to be removed, the hair dryer might be powerful enough, just be careful not to overheat the unit.
Heat guns are often made to industrial-strength standards and are meant to do jobs quickly. They can often melt PVC and easily apply shrink wrap to gift baskets, boxes and more. In addition, many models offer variable temperature controls so you have more options available.
The other major difference is that a majority of heat guns are made to be compact. This allows them to reach into difficult places like corners with ease.
Shrink Wrap Heat Gun
Many shrink wrap heat guns are powered by propane instead of electric, although they work in a similar fashion. They are handheld units that offer a trigger and handle but they are connected to propane gas through a flexible rubber hose.
The gas bottle can be placed on a trolley for safety so moving around the object is easier. Gas gets drawn out of the barrel when the trigger is depressed. It then mixes with air in the barrel as well. An electrode generates a spark which then ignites the gas/air mixture to create a flame.
There are safety measures included with these guns. For example, if the trigger gets released or the gun gets dropped, the gas is cut off and the flame will be extinguished. In addition, the burner tends to be protected by a cowl to avoid burns.
The shrink wrap heat guns can seem a little intimidating to use. The flame is visible and operation can be noisy. These guns tend to shrink an oval areal of 30 to 40 centimeters in diameter at a time.
Tips & Tricks When Using a Heat Gun
The heat gun should always be held at a 45-degree angle from the work. You also don’t want to keep it in the same place for more than a few seconds at a time.
When stripping paint, it is important that you use a scraper once the paint begins to bubble. If you continue to heat the paint after it bubbles, you could burn the paint. If you find that there is some paint which is difficult to remove, don’t continue using the gun on it.
This can damage the wood or metal that you are heating. Instead, you can sand the surface for a quality finish.
Here is a general guideline for the amount of heat you need for each project:
Safety Tips to Follow When Using Heat Guns
Heat guns can easily reach temperatures exceeding 1000 degrees (F). Instant burns, fire or injuries can occur in seconds. Therefore, you should pay special attention to the heat gun, the heated items, and the surrounding area. Below are a few tips to always keep in mind.
In addition, you might find these safety tips to be helpful:
An occasional DIY’er may opt for the simpler and more modestly priced guns, which have everything you need to get the job done efficiently.
On the other hand, if you’re a contractor planning on lugging your heat gun through construction sites, you may want to go for the more advanced and heavy-duty models like the Dewalt and Bosch.
These are guaranteed to stand the hardships and dropping they may sustain. You can’t go wrong with any of these choices.
Depending on the job and your budget, you can decide on the best heat gun here for your individual needs to get the job done.
