Rent or buy a steamer made just for removing wallpaper. Best and easiest, especially if you have a lot to remove.

Score paper with a scoring tool made for scoring wallpaper.

Try not to tear the paper on sheetrock, it's a pain to fix for us amateurs.

Recommend you try one method, your wife another. With 2600’, you will get some experience. In addition, not all wall paper is the same and you may have different adhesives.

Score the paper with a roller, spray with wall paper remover, peel.

Most wallpapers have the decorative sheet of vinyl or paper stuck onto another layer of kraft like paper. I found that the wallpaper scoring tools don't really do much to help removal. On the other hand, you can usually just peel the two layers apart like the skin on a banana. Start at a corner, and it should peel right off, leaving only the underlaying paper stuck on the wall.

Fill a spray bottle with lukewarm water, and spray the paper until it is saturated. Keep spraying from time to time to keep it saturated, and after around 5-10 minutes, it should peel very easily from the wall. You can use a putty knife, ideally plastic, but don't force, or you might damage the sheetrock underneath.

Once all the paper is removed, you need to wash the walls thoroughly to get rid of all the paste that's left on the walls. That paste can cause problems with paint adhesion.

I actually ordered a Wagner Spraytech 915 Steamer. What’s nice about it is that besides just being a wallpaper steamer, it also come with multiple attachments for steam cleaning. For $125 it seems like a great tool with tons of uses.

So is a regular handheld scoring tool the best bet?

I hung wallpaper for years and also removed it. First you need to determine if the wallpaper is hung on raw Sheetrock. If it is you will do more damage trying to get it off. Like someone else commented. There are different kinds of paper. If it has a solid vinyl surface you need to remove the top layer first. Wet the bottom layer with warm/hot water let set for few minutes, scrap with a putty knife if it doesn’t come off easily wet again and wait a few more min. (Note if you don’t have experience with a paper tiger it can cause more damage than help.) so be careful if you use one of those. A lot of it is trail and error test small area first before starting a big wall. It takes patience and time. You will also need to wash walls down after to remove all the paste otherwise you will need to prime the wall with an oil base primer before painting.

I have removed tons of wallpaper in my life, and I found that the handheld scoring tools are pretty much useless and a waste of money. (or like my late father used to say, they are just as useful as a screen door on a submarine) Like B J Mack and I described, it is actually easier and faster to just peel off the top layer that has the printing on it. Then you might want to try B J Mack's method as he described it better than I did.. I think this method works better than any kind of steamer. Good luck with your project, and don't forget to wash the walls thoroughly before priming and painting!

Once paper is removed and you have washed down all the walls, use gardz for a primer before painting, just in case, there is a bit of residue that was missed. Hopefully all your walls has been either primed or painted before any wallpaper was put on them.

Best method may depend on how many layers you are removing. A single layer of paper comes off nicely with the peel and warm water approach. Multiple layers not so much IME. I second the Wagner steamer for those situations. You might start in a less visible spot to figure out your technique and what your wall is made of.

So far the Wagner steamer is working pretty well!

It it looks like the walls were painted prior to wallpaper, so that should be better, correct?

Yes painted drywall should be better. Way to get after it!

Please post some pictures once you get a wall or two completed.

Initially we weren’t steaming for long enough. We started using a longer steam time and now we’re able to pull off full sheets vs small sections.

What would be the best way to ‘clean’ the walls once we’re done removing all of the wallpaper?

She’s moving along on wallpaper while I’m pulling up a ton of carpet!

I use hot water and a sponge or rough rag. Keep rinsing your sponge/rag and changing water. If you do it before the adhesive dries out again, it’s easier.
