I have a patch of wallpaper in the middle of a wall I am trying to paint. Its only about 18 inches tall and 6 inches wide.
It doesn't seem to want to come off, I tried using a razor blade to take it off, but its on there too good.
I believe it to be very old, and it probably wasn't put on right (it was there when I moved in) I do not want to damage the wall... What would happen if I just painted right over it?
You can rent a steamer to remove the wall paper. You might also try wetting it with a spray bottle and letting it soak. It will be tough to not damage the drywall paper so be prepared to spackle it.
The finish you get will depend on surface of the wallpaper.
If it's a smooth paper then you should be OK just to paint over it. You will notice where the paper is though as it will have a slightly different texture to the rest of the wall.
If it's a textured paper then you'd have to use filler to smooth it out first.
However, most wall papers have (at least) two layers. There's a backing layer and the surface layer (and possibly one in between depending on the quality of the paper). Even if you can't get the backing layer off the wall you should be able to get the top layer off. Soak it (as uSlackr suggests) - scoring it first with a sharp knife or scoring tool will help the water soak through - and then use a scraper to take as many layers off as possible. It's very easy to dig the scraper into the wall so you have to take care - don't rush.
Try just taking a sponge of warm water and rubbing it over the patch and then scrapping it off. I would try this before the steamer, or if you have a heat gun this may help.
Presuming that the wall is textured, I recommend texturing over the wallpaper and blending it with the existing texture.
