How to Get a Paint Sample Off a Wall
- 1). Locate an obscure section of the wall, such as behind a piece of furniture, and hold the heat gun two inches away from the wall. Apply the heat -- heat loosens the bond paint has to wood and drywall. Rotate the heat gun in a small circle; do not hold it stationary for more than ten seconds, or you risk scorching the wall.
- 2). Watch the paint. When it begins to bubble, turn off the heat and get your scraper.
- 3). Hold the scraper at a 30-degree angle from the surface of the wall and push downward. Hold the heavy-duty plastic bag below it to catch the falling paint. Use the largest resulting paint chip as your sample.
