How to repair drywall that has adhesive patches all over from removing decorative mirror tiles?
Our 1970s original had these "decorative" mirror tiles on one wall when we purchased it. Of course we promptly removed them, but it left the drywall with patches of adhesive all over. How should I repair this wall - make it smooth again? I thought perhaps sanding all of the adhesive down, then applying new texture with a skim coat. But I’m definitely no pro at this stuff, so….suggestions?
Use a 6" taping knife to scrape off as much of the adhesive as you can get, then skimcoat the entire wall with a 12" knife. Sand the ridges, then prime and paint. You will have a brand new wall. Use lightweight formula mud. It will be very easy to sand. Hope this helps.
Sandpaper is definitely the answer. But an electric sander will do the best job. Don’t try to "chip" the adhesive off in any way because ya might pull off pieces of the wall too, which will defeat your purpose.

If you try to sand the wall you may damage the paper cover either soak the adhesive and scrape it if it goes soft or have the wall skim plastered.

Do as you said but sanding down the adhesive will damage the paper of the drywall. No big deal. It’s important to seal the damaged drywall before you put on your skim coat. Use a product like "GARDZ Damaged Drywall Sealer" on the areas you sanded, let it dry and apply your skim coat.
