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.

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.
