Question Wallpapering over backing paper primed w/oil-based sealer?

Is my plan sound?

My master bath is papered with a vinyl-coated wallpaper. The vinyl layer peels off very easily. Underneath is a firmly attached backing paper which is pasted onto a painted, sized Sheetrock wall.

I'm in my 60s and not as physical as I once was. To avoid the very time-consuming, extremely messy and physically-demanding task of wetting and scraping off all that backing paper, I've considered fixing any loose areas and seam areas with compound and then sealing everything with oil-based Kilz sealer - oil-based so it won't soak into and dissolve the old water-based adhesive behind the backing.

The backing paper is firmly in place. The bath has a ventilation fan. I want to cover the walls with a paintable, strippable textured wallpaper. The lower 4 ft. of the wall will be beadboard. No wallpaper will be around the sink or the tub/shower.

Anyone with experience know if this will last?

Welcome to the forums!

Removing the wallpaper backer is best! Generally it comes off fairly easy when wet. I usually mist the wall with water from a pump up garden sprayer. Get it as wet as you can without making a mess [rags/towels at the floor] then scrape. That said, an oil base primer will generally seal the paper but you can still get bit by any paper with a poor bond to the wall.

Did I mention it's best to remove all the paper

Mark,

Is it true that vinegar in the water will aid in dissolving and loosening the old backer/adhesive?

Some swear by it, others by adding fabric softener to the water. Personally I think as long as you get it wet - that's all it needs. The wallpaper paste is water soluble, once you get water/moisture thru the paper - it will dissolve the paste.

get it off, it has the potential to come back and haunt you regardless of how solid it appears. Nothing worst than having to re-do a project due to a ill advised short cut>
