old wallpaper adhesive removal help

3 years ago

I have read so much advice on removing the residual adhesive. The wallpaper was a horrible thick paper with medallions flocked in old gold on a whitish background. The house is 1920, the walls plaster, and the wallpaper probably 1960-70? I started the project pre-COVID and am coming back to it. A lot of things I found said the paste for others that remained was sticky. This is/was not ever sticky. Sometimes I can just scrape it off and it flakes off. The walls are not perfectly flat, so have a few gouges.

Safe and Simple does not seem to be available at the moment. I am allergic to liquid fabric softener, so did not go that route. Tried vinegar and hot water. It helped loosen some. Tried a scrubby and it seemed to wear away the top coat of the plaster around the stubborn paste faster than the paste that remained in those spots. Tried some Dawn and baking soda solution. The paste that is tough to get off is hard and slick and the color of Bondo. Now that those test patches have been wet and scrubbed, the edge has totally disappeared and a razor can't even get under it. Any thoughts?

And how do I scrape the fragile dry bits out of tight corners that have less than 2" between wall some trim around a doorway on the adjoining wall? I am going to do as much of it dry scrapping as possible since it seems wetting it with water based solutions makes it harder to get off. What is this stuff? Any other thoughts?

Luckily it is only the top 1/2 of the wall. Sadly the bottom half seems to be a pressed paper wall covering (painted fingernail red) adhered to dry wall that was then... maybe glued to the studs or lath underneath? There are no obvious fasteners visible. What happened to that plaster? Shrug. Who knows.

Have you used one of these to score the wallpaper?

From the above the wallpaper is gone and the poster wants to remove residual glue.

Painting over old vinyl wallpaper or removing?
Q

The house is 100 years old. So, 1. Make sure walls are indeed plaster. (peek behind outlet cover?) 2. See if vinyl wallpaper can be pulled off (I'm sure it's decades old). If not, do I go to steps 3. scoring the paper, using gel stripper, etc. 3. Best case scenario, how much time are we talking? Remember that it's a rental, and rental time is only one year. I'm scared that I start and then reach the point of no return... and end up with a wall that needs skim coating. Now, my impression is that it's very thick vinyl wallpaper, probably installed in the 70s, 80s. It feels plasticky, with a texture, and definitely scrubbable. Because it's heavier than normal wallpaper, I'd assume that it's been attached with a heavier paste. Is that going to be a problem regarding removal? How can I figure out what paste was used?

Sorry to hear about your experience. Mine is/was similar. I found several layers of wallpaper, with a skim coat in between, and then under that, it seems to have been applied directly to drywall. I have removed a lot of wallpaper in the past, but I ended up damaging the drywall in one room so badly, we decided to hire someone. I had several contractors come through who looked at the amount of wallpaper and wouldn't do it! One guy was willing and he starts this morning so I will see what magic he uses. If he has any tips, I will share.

Repairing old plaster walls- removing painted paper (not wallpaper)?
Q
Comments (5)
Looks like wallpaper to me :) I prefer repairs that resemble the original install method but you can also look into specific repair systems with plaster washers, or even use drywall and mud. You'll want to remove all the paper (steamer, or whatever method work ok), and anything loose. A lathe/plaster wall relies on the mechanical hold of "keys" through the lathe. Basically, the scratch coat is pushed through the lathe, and those blobs harden and hold it in place. So, you'll need to remove anything that is cracked and the surrounding area. You'll know you can stop removing once you see the keys through the lathe (ie ones that haven't broken off). The actual repair would be a pretty long post, but your basic options for further googling are: 1. scratch/brown/finish, known as a 3-coat plaster (probably what you have already). Products aren't usually carried at big-box stores, so call around to plaster suppliers or masonry/stucco suppliers. They'll be able to help you with product selection. 2. Drywall patch - a sort of 2-coat plaster system. Cut a drywall patch to fit the new hole (not too thick, might only need 1/4" drywall). Use durabond to mud it in. Finish coat with durabond. 3. Look into repairing with plaster washers (I'm not familiar myself).

How do I prep walls for painting after removing old wallpaper?
Q
Comments (17)
I usually have two or three blades so I use one to clean another which gets most of the goo off. My collection usually is a wallpaper scraper, a 4 or 6 inch joint knife, and a one inch super flexible putty knife. Then I wash off the blade in the bucket I use for rinsing the rags. Washing the walls requires changing out the water regularly. I am usually the person who gets bored first so typically I go get the clean water while my partner works on the wall. Depending on the container you use, you may be able to run a wire across the top of your container to clean your blade against. This task is one that can benefit from some combination of company, loud music and alcoholic beverages.

@kathyg_in_mi - the wallpaper is gone. I did try to score the dried glue with a razor to get more surface area for solutions to be taken in. the results were mixed. the areas that are hardened seem ready to stay. have seen some posts about applying Guardz over what does not come off. the previous owner handyman sure did like his adhesives.... so am worried that because it is not likely real wall paper paste, that Guardz won't seal it in anyway.

Get a REAL wallpaper-stripper!

* Roll/brush on a couple coats about 20 minutes apart.

* Here's the TRICK.....

* Get some light (half-mil) painters-plastic. Press it on the wall.

* The idea here is to keep the stripper from drying-out, by using the plastic film!! It's the same reason you wrap up Meatloaf in Saran-wrap!

* Leave it on for a couple hours....watch a Football or Baseball game :-)

* Then, pull some plastic back, & start scraping. Consider getting one of those BBQ Grill scrubbers with the handle & open scrubby-head. This will help you chew-thru the paste.

* Now.....rinse, rinse, & rinse again!

* Then apply a couple coats of Gardz.!

Be careful. Old bathroom (vinyl) wallpaper often contains asbestos. Removing it will release friable particles into your home and endanger the health of you and your family. It's best to wet an area and send the sample off for testing.

Do what Faron says. Commercial strippers contain enzymes to make the removal easier. And enzymes require time to work.

Alternatively, you could experiment using something like Biz laundry booster or a top shelf laundry detergent like Tide. I've not used laundry products personally so there may be good reasons not to. That's why I said 'experiment.'

Two other suggestions for removing the glue from your walls: TSP and VERY hot water. Or liquid fabric softener and very hot water. The hot water is the key.

update... i tried a few of the suggestions, there are places that the plaster scrubbed away around the area I thought was glue... maybe it is not? Am waiting for an estimate on fixing some cracks in the coved plaster ceiling, will ask about the make of the walls then too. thanks

Consider a skim coat to cover up everything. We just resorted to this!
