See the people at Your local Paint Store and buy a device which puts small holes into the wall paper . It scores the paper so that the liquid stripper can penetrate and loosen the paper. Also buy some Stripper solution. and a plastic Scraper. Score the walls and then place a few old towels on the floor under where You will be working . Then use a rag to apply the Stripper Solution and wait a few minutes .Usually the paper simply starts to fall away from the walls. Then using the scraper remove all the remaining paper from the walls. After wiping every thing clean You can apply the Primer and follow up with 2 coats of paint . If You do this You will have a nice new wall .

You will see any lines show through on the wallpaper...if and when you need to take the paper down, it is going to be a lot harder...because water/liquid is put on wallpaper to remove it, when you start painting the paper, is probably will bubble up, peel off......you can use a primer, but the same thing will happen just as I mentioned for the paint...i have wallpapered for 30 yrs...

It will likely show the crease where the wall paper meets up or over laps. If that doesn't bother you, then you can cover the wall paper with paint, and it will just appear as though it's a different type of wall paper.

Technically you can, but it will not look right. Certainly a saturated color will cover better, but it will look like painted wallpaper, not a painted wall.

It's not a good idea, it's hard to remove it but will be worth it in the end. There is a special chemical you can buy to make it easier.

you will see stripes from the wallpaper through the paint, and after you paint it, taking the paper off will be 3X as hard.

So in my bedroom there's wallpaper and it's all over the 4 walls. It has a white background with flowers on it. And I wanna paint it a different color and do one wall chalkboard paint. Could a turquoise color paint work over the wallpaper? and what about chalkboard paint? Because removing the wallpaper is tedious and expensive
