How to remove wallpaper that was never sized and has been on for 25 y?

Hi Peggy, I’ve done it with a steamer, but that was years ago. Today I think they recommend a remover. Maybe this will help. https://www.hgtv.com/design/decorating/design-101/how-to-remove-wallpaper

Very patiently. Use the wallpaper remover Dif in hot water. Spray on paper, I use a bug sprayer, but a spray bottle will work. Let soak in and scrape off with wide putty knife.

Lots of water.

If the walls were never sized or primer you will have a hard time trying to get it off. It will shred instead of peel and may damage the walls. This is the only time I recommend washing it down, priming with Kilz primer, then painting. Easy solution without the mess.

We have never used a steamer for wallpaper removal. We’ve had great success with the paper tiger wall paper perforator tool and spray on wallpaper remover products similar to these

this is the process that we used to remove wallpaper. Good luck! https://www.charlestoncrafted.com/2017/01/24/experience-removing-wallpaper/

The Paper Tiger perforator is a great tool but be careful with the pressure so you don't damage the walls underneath.

Mix 50/50 in a spray bottle: warm water & fabric softener OR warm water & vinegar

I used fabric softener. Saturate wall and let it sit to loosen the glue. Using a plastic scraper to remove. Once all has been removed, clean up with warm water and dish detergent with a microfiber cloth.
