How to Use a Heat Gun to Remove Paint

Removing oil-based paint can be a difficult chore, especially if you need to get rid of multiple layers. A heat gun can make this task easier. The idea behind using a heat gun is to actually melt the existing paint, allowing it to be scraped off. In order to melt paint, temperatures as high as 1000 degrees F are sometimes achieved, so this process must be performed with caution.

Difficulty: Moderate

Instructions

Things You'll Need:

• Heat gun
• Heavy gloves
• Eye protection
• Breathing mask
• Paint scraper
• Bucket
• Water
• Mineral spirits

1. Wear heavy gloves and eye protection when using a heat gun, and wear clothing that protects your entire body. If you are removing lead-based paint, which was common prior to 1978, wear a mask. Also, have plenty of water available in case of fire.

2. Turn on the heat gun and wave it back and forth approximately 1 inch over a small area of paint. Keep the gun moving at all times. As the paint begins to bubble, turn off the gun and immediately scrape the melted paint with a paint scraper.

3. Dispose of the scraped-off paint in a bucket and continue heating and scraping the next section in the same manner. Watch for smoldering wood and douse any with plenty of water immediately.

4. Apply mineral spirits to scraped areas to remove any last remnants of paint.

Tips & Warnings

• Dispose of all removed paint properly. Consult your city's health department for instructions on disposing of lead-based paint.
• Do not use a heat gun around windows. The heat will shatter glass.
