Painting - Removing wallpaper glue

I've been able to remove the wallpaper using a Wagner Power Steamer very easily. My problem is that the glue doesn't come out with the wallpaper... :(
What is the best way of removing it? I planning on prime it after with Primer Zinsser Bulls EYE 1-2-3. Is it a good one for the job or does any one has a different suggestion? FYI, the wallpaper is applied on top of a previously painted wall.

Thanks for any help,

Scraping and washing with solution of DIF and water is probably the most effective

If it is not all completely removed, Zinsser's Gardz is the best primer
It will seal and harden it right in there

use a mixture of water and TSP. It should take the glue of glue off, assuming of course that the wall was prepped properly prior to the wallpaper application.

Hello,
I use an electric sander with 220 grit paper to remove the bulk of the glue.
After that, I wash it down with water and either DIF or a mixture of vinegar and water, then rinse with plain water.
DIF is supposed to attack glue - I've fared about 50/50 with it.
Vinegar added to the water simply acts as a wetting agent to slow down the evaporation.
TSP (tri sodium phosphate) will also retard the evaporation. TSP (non-phosphate) substitutes generally won't. TSP is getting hard to find in some areas.

Pick up a cheap (WalMart has a Black and Decker 1/3 sheet sander for under $20) sander and a "peanut" sponge (one of the stifff sponges shaped like a peanut) and maybe an empty 5 gal pail.
Change water often. <-- biggest mistake most people make is not changing the water often enough. All that does is reapply more adhesive. If you can see the water turing color, it's well past the time to change it.

Dried wallcovering adhesive sands very, very, very easily. In the time I've taken to type this & you to read this, I could have sanded about 95% of the dried adhesive from a decent sized wall (8x8).

I second the Guardz as a primer.
The 1-2-3, while excellent, is overkill in this situation. 1-2-3 is an interior/exterior product and is priced accordingly. It's best use is on exterior hard to hold - such as vinyl siding - surfaces or for killing some stains.
Guardz is a slower drying material, designed to give maximum pentration of binder/resin/pigment into a porus substrate.

P.S. Taking off wallpaper is fun eh? LOL!
My wife and I just got done removing 4 layers of old wallpaper from a kitchen. The previous owner had papered, painted over that coat of paper, the repapered, then repainted, then papered and papered over top of that one. Since the paper had been painted over the steamer didn't work. We had to "dry shave" it all.

IMO warm water and elbow grease works as well as anything. I always sand when dry and IF there are any areas that the glue won't remove - prime them.

I just removed the wallpaper in one of my bathrooms and ended up soaking the remaining glue with DIF and letting it sit for a few minutes. After everything was soaked in, I used a stiff bristle brush and a mixture of water & Dawn to scrub the wall down. Once it dried, it was perfect.

Usually warm water and elbow grease will do it. The last paper I took off had so much glue, I ended up spraying it with water in a spray bottle and using a scraper. I'd wipe the glue off on a paper towel. I've never seen a wall with that much glue!

save your money.... use an old spray bottle...fill it as hot as u can get it with water, maybe add vingar (75 water to 25 vin.)..either way soak a strip of that adhesive..... u know like 3x8 whatever....soak it all, then pick at a corner then carfully peel a way you'll remove the whole strip, u get the rthymm and you'll be done within minutes...you can do it this way or TRY and find a better way over a period of days....but just apply yourself and get it done...It's not super fast and easy no matter how it's done....P.S. if u have toddlers....they're very good at being destructive have them help!! give them simple instructs and ur on your way back to a bare wall (ready to go)
