drywall mud texture over old wallpaper


I have an old ceiling I just want to texturize with drywall compound. Amazingly this ceiling is wallpapered. Looks very old but fully intact. Plaster underneath. I know this is a strange question, but can I just texture over the wallpaper? I'm thinking the water in the drywall compound could cause the paper to loosen so perhaps i could douse the walllpaper in warm water, remove any loose bits then proceed covering whatever didn't easily come off? This is a bedroom, I'm alittle burned out on home improv. projects (been doing them for 5 flippin' years) so looking to do it fairly quick and easy, not perfect

No. Not even for a 'not perfect' job.

Soak the paper in hot water with a garden sprayer and 9 times out of 10 it will fall down in full sheets.

I will try that Chris. I had used DIF in another bedroom on a border and it didn't do much. Ended up just priming and painting over the border and magically it disappeared.

Annie - I also use hot water in a garden sprayer for removing paper. I toss a little vinegar in too, cause I like how it smells

Since you'll be spraying the ceiling, you need to protect the floor/switches/outlets with some plastic.

Get rid of your paper tiger and get a 2-3 inch wide putty knife with a little flex. For a large area i usually work with two sprayers so that i dont have to keep making trips to re-fill.

What has worked for me is the following:

1. Spray entire area until dripping.

2. Re-spray a workable section (10 ft square or so).

3. Give it a minute or two (but not long enough to dry out) Start peeling off the paper using the putty knife - like Chris said, it should start to loosen and (keep your fingers crossed) fall off in big sheets.

4. As soon as it gets a little hard to pull off; re-spray the area you are working on and the adjacent area. You should be working damp/wet, if things start drying out spray spray spray. This isn't scraping paint. If it gets hard to remove the paper don't just scrape at it -WET IT DOWN MORE! If you think you are spraying enough... Spray it all again. You cannot get it too wet nor can you spray it too many times.

5. Once you start getting the paper down in large pieces make sure you are bagging it right away- the semi-wet paste (am i allowed to call it paste?) makes a mess on the floor and if allowed to dry will re-adhere the paper to whatever it's touching - like baseboards.

6. Once you successfully remove every last scrap of paper [YAY you!!] the ceiling needs to be thoroughly cleaned to remove any residue before priming and finishing however you like.

Here's why I discourage people from painting/coating over paper:

My last paper removal project was four layers of paper in a 130 year old room.
- the outermost layer peeled off as soon as it got saturated- came down in great big sheets and sometimes took some of the next layer with it.
- the next layer required soaking several times before it separated
- the next two layers were the biggest PIMA! it took CONSTANT wetting and a great deal of elbow grease to get that mess off. At some point I was reduced to using a razor blade to scrape off postage stamp sized pieces. All because someone painted between two of the older layers of paper :angry:

I probably sprayed a total of 40 or 50 gallons of hot-vinegary water on the walls over the course of removing all the paper.

But the bottom line was that it HAD to be done. The paper was failing at various places in varied layers and painting over
It or papering over it would have been temp fix that would look bad and that would result in certain failure later.

Phew. Lot to get off my chest, but looking at my gorgeous pristine plaster walls makes me really happy and makes it worth it.

NO, adhesive is now the term

Ok- this is like top secret but I'll let you have it if you don't tell anybody. After you soak it good, cut 4' sections of light painters poly (9'-12' more than the height of walls)and with a dry rag press it on the wet walls. Will hold the water in so you don't have to work so hard at wetting it. Pull off A section at a time and fully strip and clean glue b4 moving the next one.
Beats a steamer or a tiger. This rocks. But don't tell anyone.

Thanks everyone, I see that it will be necessary to remove the wallpaper, oh how I dread it! I knew it was wishful thinking that I could just take a big shortcut, rarely does it work out that way. Your instructions should help me alot. I figure the money I save doing the project myself will pay for the many visits I'll need to the chiropractor and massage therapist

Of course, you can call it glue if you wish too, but be ready to duck....
