You can remove paint from the following surfaces using a heat gun:
While you will realize that the methods to remove paint from a surface, no matter the material is the same, unfortunately, you will need to keep in mind a few precautions. These precautions are material specific so you need to be aware of them all in case you end up making a mistake.
When you heat metals, you need to wear a respirator or at least a decent mask as the metals will release toxic fumes that can be potentially dangerous for you to breathe around. A good way to make sure you don’t face this issue is to work outside. However, if this is not accessible to you, ensure that you work in a well-ventilated area.
Concrete is another material that you may use a heat gun on to remove paint. However, unlike metal, this surface can be damaged with the high temperatures of a heat gun! That’s why it is recommended to not allow the heat to go beyond 1000-degrees Fahrenheit. You also need to remember that concrete contains pores that will be stained by the paint. You can peel off the paint layer but unfortunately, the stain itself cannot be removed.
The same can be said for stone surfaces. They are porous so the paint can get into the pores. You won’t have much luck using a knife to scrape the paint away, so a ball of steel wool might be better suited to the task.
Where can you not use your heat gun to remove paint?
Any painted area that contains paint consisting of lead is not a recommended job for a heat gun! Mostly any paint job before the 1980s comes into this category but you can also find brands that still incorporate lead, so it is important to be vigilant.
In case you are unsure whether the paint has lead in it or not, it might be a job best left for professionals to tackle. You might have to deal with toxic fumes being released from the paint if heated via a heat gun. Professionals will have the right kind of gear and equipment needed to tackle this.
Heat guns are also not recommended to remove paint from plaster walls, since it might not only remove the paint but can also damage the surface.

Work in an area that is well ventilated. We also recommend that you do not use a heat gun if you have no prior experience. You should start slow, such as for DIY crafts projects and then move on to something as advanced as peeling paint off using a glue gun.
- We have discussed this before; certain metals can cause the occurrence of toxic fumes when it is heated. So, it is recommended that you use wear gas masks as this can allow you to reduce the danger of accidentally being exposed to these fumes. A respirator is the best option but gas masks can also be quite effective.
- Finally, we suggest that just as you aren’t allowed to use heavy machinery under the influence or using medications, make sure you are focused when using a heat gun. If the heat goes up to 10000 degrees F, it might cause great damage to you or to any surfaces it comes in contact with. So, caution is necessary. If your skin comes in contact with the heat, it can cause severe burns!
The important aspect to remember about your heat gun is that it is like an industrial-sized hairdryer! So, it is easy and hand-held to use but you need to be careful. We recommend that you wear safety goggles, gloves, and a mask for the coming procedure.

- Your next step is to heat your heat gun! You will need to plug the gun in for a while before it is used. It can take a few hours to heat up so you will need to be patient before the magic can happen!

For this, we recommend that you bring your heat gun as close as possible to the painted surface. Do this slowly and carefully getting each corner and part. You will keep heating the surface till you see that the paint is bubbling up and it begins to melt.
- For your next move, you can begin scraping the paint off now that it is easier to remove. Dry paint will chip and take ages to come off but melted and gooey paint can be scraped off. You might get some bits of paint left behind that cannot be scrubbed off, however, we will deal with them later. The goal is to get as much paint off as you can.
- Now that most of the paint has come off, your next step is to add some important ending touches to your work. This is when you can bring out the steel wool and use it to slowly scrape off the leftover bits of paint.
- Finally, to complete the job, you will use the cloth and white spirit to rub the entire surface. With this, your surface will become completely free of any residue of paint that was there before.
