Painting Dry Wall
Just spend a weekend removing some really gross old wallpaper in a bathroom. Down to the drywall.

I read There are primers you can put down that essential seal the dry wall before the paint goes in. Alternatively you can just do a bunch of coats.

Anyone have experience on way or the other? It’s a small room so multiple coat probably isn’t too hard.

re: Painting Dry Wall
I am sure by now there is one specifically for this purpose, saw they now have one to protect against mold/mildew. When we removed some wallpaper the contractor told us we needed to use an oil based primer, one coat. The thing we were told to watch for is if there is any additional peeling/bubbling when the primer is wet. Still only used 1 coat, but had to go over some sections a few times

If you don't normally wear gloves when you paint, I'd suggest you do for the primer in case there is some peeling/bubbling.

Use an oil based primer before painting. I've used regular old Kilz oil based primer in the past for walls that previously had wallpaper and years later there have been no issues.

The stuff is a great primer but be sure to have the area well ventilated as it is pretty pungent and will get you lightheaded after a while. The oil base stuff that is.

The latex based Kilz is much easier to work with, breath without a lot of nasty fumes and cleans up with soap and water.

If you decide to use oil base Kilz, use a cheap brush and roller and just throw that shite away when done. The cost of mineral spirits to clean equipment from oil base paints is stupidly priced.

Oil based Kilz is great stuff but it will knock you on your ass.

I suggest using that with the windows open, fans going, and an N95 mask on.

re: Painting Dry Wall
You might think you have it all, but likely some glue spots still on there. We just painted when we though we had it all and just wasn't smooth. Now I'm having to skim coat it and repaint.

And I second Kilz.

re: Painting Dry Wall
Was my first time removing wall paper so maybe somebody else with more experience can comment whether I just suck at it or its an issue. I used the piranha paste remover and scraped everywhere. Looked clear but could see the uneven texture when painted.

Luckily this is only a half bath so skim coating the walls isnt a big deal.

re: Painting Dry Wall
Similar situation but I used Hot water and a putty knife.

I’m thinking I just Maybe doing a really light sanding with one of those dustless sanders before I paint.

A lot of times the walls that get papered are not "sized" meaning primed with something prior to papering. If that is the case, removing wallpaper is often a real PITA as the wallpaper coming off will sometime remove the top paper layer of the dry wall.

It will come off easily and cleanly on taped seams where the sheetrock mud is, but it will often chew up the bare paper areas.

If you are a little suspect about the condition of the walls after removing the paper, you can either blow on, or roll on a bit of texture and that will hide some of the "sins" of small imperfections caused by removing the paper.

This is the correct answer. Gardz is water based, no mess and smell like oil based. Be sure to apply enough that it soaks in to the wall and still leaves some on the surface. We did a hotel remodel where we removed old vinyl wallpaper that tore the top layer of drywall up. After removel, we coated the entire wall with Gardz, which locked down the torn drywall and prevented the torn drywall from bubbling up when the walls were skimmed. After the walls were skimmed, we coated the entire wall again with Gardz and then sprayed a light orange peel and painted. No problems. Gardz is very thin, so it goes a long ways. We used dozens and dozens of 5 gallon buckets of Gardz on that job.

re: Painting Dry Wall
I just did this in my pantry and I used Gardz on the recommendation of this board. It blocks any little pieces of drywall paper from bubbling up. It also creates a nice smooth, hard surface.

Helpful hint: It's SUPER thin so it does take some getting used to but a little goes a long way.
