Wallpaper Removal Techniques

Here are a few techniques for wallpaper removal.

Vinegar Water Mixture

To make a vinegar-water mixture, you will need a spray bottle, a cup of white vinegar, and water. Fill the spray bottle most of the way with water then add vinegar until the bottle is full. The amount of vinegar you should use depends on how strong you want the mixture to be. A 50/50 mix of water and vinegar is usually strong enough for most applications. Be sure to shake the bottle well before using it to mix the ingredients together.

Spray Hot Water

Pour hot water into a spray bottle and begin misting the wallpaper. Make sure to saturate paper well but be careful not to get the wall too wet or it could damage the drywall underneath. Allow the hot water to soak in for a few minutes then begin scraping the wallpaper away with a putty knife or other sharp implement. Repeat this process until all the wallpaper has been removed.

Steam Removal

This method is best suited for vinyl or pre-pasted wallpaper. To begin, fill a large pot with water and bring it to a boil. Next, hold the pot close to the wall and direct the steam onto the wallpaper. Be sure not to get too close or you could damage the wall. After a few minutes, the heat will cause the wallpaper glue to loosen and you should be able to peel it away easily. If necessary, you can use a knife or other sharp implements to scrape off any stubborn bits.

Chemical Removal

There are several commercially available chemicals that can be used to remove wallpaper but they can be quite toxic so it is important to use them safely and according to the manufacturer’s directions. You have to follow safety tips against the chemicals and for a chemical emergency, you can contact the helpers. Generally, you will need to apply the chemical solution with a sponge or brush and then wait for it to soak in for a few minutes before attempting to remove the wallpaper. Once again, a knife or other sharp instrument can be used to scrape off any bits that are resistant to coming loose. After removing all the wallpaper, be sure to wash any residual chemicals off your walls with soap and water.
