How to Remove Painted Stucco From Interior Walls

While exterior stucco is a portland cement-based material applied over metal lathing, interior stucco is created using a faux material like joint compound or a thick plaster. When you are remodeling and need to remove painted stucco from interior walls, the process is easier than removing exterior stucco, but still time consuming and labor intensive. You must exercise caution during the removal so you do not damage the drywall underneath the stucco coating. It is a tedious process, but not a difficult one.

Interior stucco is designed to be long lasting, and it takes work to remove it.

Step 1

Prepare the room by removing the furniture and other items that you can. Protect the rest of the area with plastic sheeting or drop cloths. Make sure the entire floor is protected as well.

Step 2

Score the stucco by placing a 4-inch metal paint scraper against the stucco and tapping the end of the handle with a rubber mallet to break the surface of the stucco. Do this from the floor to the ceiling in a straight line every 3 feet along the wall.

Step 3

Fill a spray bottle with warm water.

Step 4

Spray the entire stucco surface of the wall, concentrating on saturating where you have placed your score marks. Let the moisture soak in for 10 minutes and then spray the surface again. Do this until the stucco begins to feel loose or pliable to the touch. Do not use a pressure washer to soak the wall. A pressure washer will put out too much water and pressure and potential damage the supporting wall behind the stucco.

Step 5

Place the blade into one of the score marks and then tilt the handle down until it is at a 30-degree angle to the wall. Tap the end of the handle gently with a rubber mallet to start the scraper under the stucco layer. Remove the rest by scraping it by hand. Reapply water to the stucco as necessary to soften it.
