Popcorn texture is an inexpensive way of covering walls or ceilings with a something a little more interesting than plain paint. Once on, however, you cannot apply a different wall treatment without first removing the popcorn. If you decide you want to remove popcorn texture from your walls, it is not a difficult job. If you have a large wall or walls, it make take some time to get done, however.
Remove any furniture and wall fixtures from the room you are working in. Lay a plastic tarp across the floor and tape it around the edges of the room.
Spray a small portion of the wall with water from a spray bottle. Apply water until the popcorn is damp.
Hold the drywall blade so the blade is upright and flush against the wall where you sprayed the water. You should hold it so the blade is at a 30-degree angle.
Gently push the blade up, scraping the popcorn texture off the wall as you push. Scrape away all of the damp popcorn in the same way.
Spray another portion of the wall and scrape off the damp popcorn. Keep doing this until the wall is clear.
Wrap up the plastic tarp and throw all of the scraped off popcorn away.
