Can you wallpaper over the textured walls?
 

How do you wall paper over the textured walls?

not without getting bumps. etc. To put up wall paper you need a flat surface.
You can get thin sheet rock and put it over the wall you want to paper.

I have done it in a small guest bath, but keep in mind that the result will have a textured surface, so choose your wallpaper with that in mind. A paper with a random pattern and textured finish will have better results than a smooth finished paper. You also will need to be more careful finishing the seams, but it is ok to do and looked nice as long as you are ok with the texture. The difficult part was removing the paper when we decided to sell our house. That was a stinker.

We have textured walls up north. The decorator put up a heavy plain wallpaper first, then the wallpaper over that. Quite a job but it looked good.

the texture is basically splattered plaster, so it's very hard, then it is painted.

I wanted a smooth wall in an area, I just sanded it down with 50 grit sandpaper.

Messy, very, need to drape plastic all around.

I didn't think many folks did wall paper any longer?

According to all the decorating magazines and blogs, wallpaper is back in. How that translates to the rest of us, who knows?

I did something similar up North, over a SAND PAINTED wall. After spending hours (no make that days) getting most of the sand off, I found a great wallpaper that looked like cloth. I used a separate paste (as opposed to pre pasted) due to the imperfections in the wall. Took a while, but it worked.

I used the white liner in our NJ kitchen. The whole house had sand painted walls--I bet what village tinker has. It worked fine.

And yes, wallpaper is coming back in style.

The easiest way to smooth the textured wall is to apply a skim coat of drywall compound to the wall using a 12 inch putty knife. Apply then lightly sand area and make sure to seal with a good sealer/primer before applying wallpaper

I know someone who was in the paint/wallpaper store business for his entire career.

He told me that when borders appeared and became so popular, he knew it would kill the wallpaper business. -- I am trying to remember when that Trojan Horse full of borders showed up in decorating. Seems like it was during the peach and teal era.

I have not used wallpaper since 1987 when we bought a house where we had to strip a big room. I remember rolling off blobs of glue the size of basketballs and swearing, "As Traditional Home magazine is my witness, I will NEVER have wallpaper again."

But. . .you know what...I just bought some brown towels. I have not bought brown towels since the earthtone era. Was that the early 80s?

So with decorating, we just never know what might start looking good to us again. (I digress. All the OP wanted was some DIY advice. Not a flashback to my decorating past.)
