How to remove wallpaper?

Age of wallpaper and on drywall or plaster?

I use a 50/50 mix of vinegar and hot water in a spray bottle. Spray it on the wall and let it sit for a while. Check every so often if the wallpaper can be scraped off with a putty knife. Use the same mixture to clean the adhesive residue with a sponge. Let dry. Prime and paint.

Some wallpaper can be removed with water and a plastic scraper. Just pull it off. Other wallpaper types need a steamer to remove it. And others require the chemicals. It depends on the type of wallpaper and thickness. It also varies if a homeowner installed it or a professional. Professional installed wallpaper is MUCH harder to remove. Clean off all of the sticky goo with water and vinegar. Good luck!

Before you make any investment, try this. You need a spray bottle filled with hot water. Spray about 3 panels of the wallpaper very liberally, walk away for 30 minutes, come back and spray again two more times (spray and walk away for 30 minutes x 2). FROM THE BOTTOM UP, start tearing the paper up very slowly, jerking as you go. If the paper tears, just scrape it up with your fingernail and continue jerking the paper up. Continue on in the room the same way doing 3 panels at time. To remove the glue left on the walls, you’ll need a bucket of warm water and an old broom. Wet the broom in the hot water and start washing the wall with the broom which will break up the remaining glue. Then wipe the walls down with a soft cloth dipped in warm water. The broom will be shot when you’re done so you’ll have to pitch it. This worked for me and I removed 3 rooms of wallpaper that were 25-30 years old. Good luck and let me know how it turns out!
