I painted over some cheap wallpaper and it bubbled. Now what?

Question

Should I re drywall the whole room? Should I just leave it and hope nobody notices?

Answer 1

No need to go to the expense of new drywall.....sounds like you used latex (water-based) paint over the wallpaper, so what happened was the water in the paint softened the wallpaper.

If the wallpaper will come off easily by adding more warm water in a spray bottle, then remove it entirely, then wash, sand, and apply oil-based primer, and top coat with latex paint.

If the bubbles are few and the rest is still stuck down ok, then remove the bubbled pieces, let dry completely, sand any rough edges, prime with an OIL-BASED PRIMER, then 2 good coats of your tinted latex paint.

If the removed bubbles of wallpaper leave a noticeable gouge in the wall , then fill with some pre-mixed drywall compound, then sand smooth, then go ahead and prime and paint.

Sounds like a lot of work, but much much cheaper than drywall.

Good luck !!

I cannot tell without seeing it why you are getting bubbles. But under no circumstances do you ever size the walls with glue or PVA prior to applying emulsion. This is a recent idea that I and other apprenticed decorators were not taught in college and I think it is a flawed idea. Are you using old, cheap or overthinned paint? If the bubbles keep appearing in the exact same place then after rubbing down seal the surface with some Bullseye 123 primer (you'll have to go to a proper decorators merchants for it), or if you fall over when you see the price of it, a little oil-based undercoat.

Try to make a small cut in the wallpaper with a straight razor or sharp knife, take a damp sponge and go over where you made the cut, it should lay back down, if it don't put a little Elmers glue over the slit you made with the blade and work it in to the cut, be sure to wipe any excess glue off of the wall as it will yellow with age....you may have drywall behind the wallpaper if all else fails remove the wallpaper and repaint....

Answer 5

Talk about extremes!!! Your paper didn't bubble because it was cheap...it bubbled because it wasn't on securely to begin with and you used a water based paint. You're going to have to wet sponge that room down and scrape it off, section by section. Start where the biggest bubble is and work from there. If it bubbled near seams, you can try re-pasting it to the wall.

Answer 6

1st the paint loosened the paste from the wall paper, causing it to bubble, if there is not allot of bubbles you can cut them out with a razor blade, try spackling (not sheet rock mud) to smooth over your cut outs, sand , and repaint.... the reason behind using spackling it will dry faster than sheet rock mud and Maybe you want get anymore bubbles,,, PS use a hair dryer to speed things up ,and you might want to prime your spots with a cheap spray can of paint,it has no water in it , (you can do it)
