How do you paint over wallpaper?

It has been proven it will not work. Eventually with moisture etc. the wall paper will bubble and will be worse down the road. do yourself a favor and look to remove and start over.

The problem is the 'wet' of the paint can soak into the paper and lift its glue, thus bubbles. The warmer and drier the room, the faster drying the paint, the less wet the paint, the quickness you put it on, all can be factors. Heaters, vents, fans, add dryers to the paint, all may help. Good luck.

I just finished doing my front room first you have to patch seams with dry wall mud and sand when mudd is dry then primer the walls then you are ready to paint

do yourself a favor and remove the exsisting wallpaper. It is so proven it will not be to anyones benefit long term, You can read others stories,however different homes maybe it worked for them and maybe they are just saying it worked.Honestly at this point follow your own instinct.

I painted my livingroom wall, which had paper on it back in 1991. It had some fuzzy pattern which remained but the color was fine. It never came loose or failed in any manner. It was painted with regular interior wall paint in RED. It looked great until I decided to tone it down with gray stripes late last fall - 2016. That's 25 years!

Because the sheetrock was very old and wouldn't allow me to install one of the little wall fireplaces using molly bolts, I had my carpenter simply cover it with new sheetrock. The house was built in 1972.

Try painting it if that's what you want. You shouldn't have any problems!

When budgets are tight, necessity is the mother of bravery. We bought an old house in the early 70s which had several layers of wallpaper in every room. There was no money for sheetrock at the time, but I had been given some leftover paint and decided it couldn't possibly look worse than it already did, so I got a pan and roller and painted it. The paper bubbled almost immediately as the paint soaked in and I was seriously about to panic, but I persevered and finished the job. Wonder of wonders, the paper shrank back down and flattened out as it dried. It wasn't perfect, but it was a heck of a lot better than it was when I started. This was old-fashioned paper, though, not the vinyl faced stuff that's used today, so your results might be different.

I have, but you do have to do some prep work first. My kitchen had paneling with wallpaper clued and nailed to it. When trying to remove it failed I spoke to a paint store. They suggested buying wallpaper liner and hanging it horizontally over the wallpaper. I did this, let it dry for a day and painted over it. Perfection, 20 years later and 2 color changes and absolutely no issues. Not only did it eliminate the seams it covered up the paneling grooves.
