The products you are useing are the ones I would go with, but are you giving them enough time to work. You should let the removal product set at least 20 minutes and you should apply it at least twice which means you wait at least 40 minutes before you start doing anything to the wall. The best way to apply the remover is with a pump up garden sprayer and be sure to start at the bottom of the wall and go up. If you can not get all of the adhesive off this way then sanding is your last resort and if you can not get all of it off you will need to prime the walls with Bin primer from Zinsser and then you are ready to start repairing the walls.
If there is any other wallpaper in this house I would not remove it but just prime and paint over it as you have found out it really becomes a part of the wall when they were not properly prepared to start with.
Good luck.

I have waited. What is left on the walls is only wallpaper glue and in some spots very thick. I have sanded about a 1/3 of the area. Next I will go back over the area with warm water and TSP or DIF and then rinse again, prior to repairing the walls. Is the Zinnser brand the only thing you recommend? I bought KILZ Oil Based Primer to put over the prepped walls prior to painting.

I have found out that the BIN primer which is a white pigmented shellac ( there are other brands) holds back the staining from the adhesive left on the wall better than an oil based satin killer such as KILZ.

There have been some changes in things since this post started. I would use the DIF Gel remover to get off the glue that is still on the wall. Then you should prime with GARDZ from Zinnser which will hold back any remaining glue and it is water based, which means very little odor.

Hope this helps out.

I have 40 year old wallpaper glue that is heavy on the non primed drywall. I had tried everything including steam, DIF, and fabric softener. The only thing that really helped us was Krud Kutter, degreaser with the orange/red label! Spray on well, wait 5-7 minutes and use a plastic spatula to scrape off the glue! Follow with a wash of warm water/vinegar! I did most of my house this way. The wall paper was vinyl with gauze on the back and let me tell you it had an embossing on it that made it impenetrable with the scoring tool that is sold. Good luck! You can find the Krud Kutter at your local home store in the painting section!.

Sounds like you have a real problem. Is the entire wall crackling, or just certain areas?
I have never dealt with this. I suggest that you post this as a new question. More people will come across it and hopefully come up with a solution.

Previous owner painted over wall paper glue I think. I did not realize it till I was done painting one room and noticed the terrible texture in some spots. Coverage in those areas was poor despite two coats of decent Behr paint. Discovering the same thing in another room. not sure what to do. I have done a lot of wall paper removal and know it is too late to get the glue residue off. it is painted over. I am a DIYer. But not a lot of time. Will primer help? What kind?

I removed my backsplash in my kitchen and the adhesive is very hard to remove. I would like to put different backsplash on my kitchen walls, but I need ideas of how to remove the adhesive. I have tried liquid glue removal and a little sanding. Any thoughts what if I can get it all off can I just add my grout and then my backsplash? Help!!

i'm dealing with the same problem. thought i got all the glue off my wall where i had a wallpaper boarder. i'm going to just try (in a small area) some good primer. hope this works.

For walls covered in wallpaper that is firmly fixed, a lot of time and effort is needed to remove the paper. During the process it is highly likely that the surface of the drywall will be damaged, needing additional time and effort to restore. After this, the surface is still likely to be less than perfect, and painting may not be completely successful.
In severe cases like this, it is faster to remove the drywall and replace it with new sheeting. This material is cheap and easy to work with, and will give a finish that is as good as new. This has the advantage of giving access to electrical wiring and other services if any changes are needed. If you don't want to remove the old sheeting, consider fixing the new sheets over the old. Make sure you find where the studs are before fixing.

Quicker to tear out all of the walls and re dry wall the room? HA! We used Guardz over the remaining wallpaper sizing/glue and it worked great... First we peeled away the top vinyl layer of wallpaper, then for the backing (on the wall) we used a pump sprayer with hot water and fabric softner.. spray it on, wait 10 minutes, then use a wall scraper.. it came of in sheets.

After that we did a quick sanding of the walls, then used Guardz to seal up the glue. Some light patch work followed, then came the paint.. done..

The time it would take to tear up a room, removing drywall, re installing it, taping mudding, sanding and priming would be twice what it took us to do what we did..

Not to mention, if you have several rooms to take care of, do you really want to tear everything down to studs? Most of us would not, but if youre handy enough thats all you!

I have the same issue, will try the hot water and fabric softener... what ratio do you use? I have the concern that the walls were not primed before this old (40 years) wallpaper was applied, so for the small spot I tested, that the knockdown finish (I'm in California) was starting to dissolve if I got too aggressive in trying to scrub the hard, dried paste off. I will try a longer wait time to let the mixture do its thing.

Six months ago I removed the backsplash from my kitchen and the adhesive left was thick. Everyone told me I would "just" have to replace the drywall. That's a big "just". Anyway, I noticed the adhesive bubbled and would just scrape right off behind the coffeemaker and over the stove so this weekend I got out the steamer!! I got all the adhesive removed in a few hours using steam and a scraper. No chemicals and free!!!

Looks more like a white paint after I removed the wallpaper. It is thick and uneven...could it be a wallpaper paste? Can I paint over it if I sand it down as opposed to trying to remove it?

Can I prime and paint over wallpaper?

I just wanted to put my two cents in on this. If you are dealing with a waterborne paste, then try to take off with some kind of wallpaper stripper. I’ve used Chomp before and you can let it soak 1-5 minutes then take a plastic scraper and without applying too much pressure, just enough to get the glue off, careful not to take any Sheetrock mud with it, then rinse and let dry. If there’s still residue then sand. It is true that you will want to use Zinsser Gardz or an oil primer after that. I’ve used both and have had great luck with both. I don’t know how Gardz does it, being a waterborne product bc the rule of thumb is if it’s waterborne then use oil to block and vice versus but Gardz somehow works. You’re basically trying to stop the old glue from coming in contact with water and reactivating, somehow Gardz keeps the glue from reactivating. That being said if in doubt on what kind of glue you’re dealing with use oil primer. If the wallpaper is really old then chances are you’re not dealing with waterborne paste and it would be best to use an oil primer.

I'm trying to remove very old paper wallpaper that was put right on top of the untreated sheet rock. Putting any liquid (fabric softener, glue temper, etc.) on the leftover glue (after stripping the paper off) is just melting the sheet rock. What can I do?
