Wallpaper down. How to proceed

Need quick advice. This wallpaper was hung 30 years ago on unprimed drywall. The paste left over is mostly intact. Instead of steaming or soaking this off along with the top layer of the drywall, can I just shallac or oil prime over this?

What could go wrong?

If you are talking about priming over the paper backing, keep in mind that just because it is stuck tight to the drywall paper does not guarantee that it won't come loose from the mud joints once it gets wet with the primer and paint. You may want to wet a test area to see how it reacts before using the Gardz, or whatever other primer you have in mind.

SW has a product called drywall conditioner that is supposedly a Gardz equivalent. I was hesitant to do the Gardz because it's water based and the old school train of thought says you shouldn't put water based anything on water soluble wallpaper backing.

I ended up steaming it off any way and used SW water based pro block as the primer. But only because I had it left over from another job. 😀

Just to update the thread, this was the most disgusting wallpaper I've ever taken down. I ended up using my trusty Wagner steamer which worked great. The problem was the nasty gobs of paste along with the release back paper. It was a mess.
