Has anyone done the paper bags on walls and then painted over them?

Then make an underlayment for wallpaper for rough walls..... the 1000 is the thickest...https://www.youtube.com/watch?v=643EXhB5jpw

or you could skim coat them with joint compound and even put a texture on them with a texture roller..... https://www.youtube.com/watch?v=zH-_yNUH2-s

Yes I have used the brown paper bags on my walls and just used a latex paint. Works great. I also used old outdated ugly 70s wallpaper in place of the brown paper bags. If you paint the wallpaper first (any color) then tear in irregular pieces you can give the walls the appearance of ancient walls. I first tore small paper pieces and it was time consuming, which I am a impatience person, so I finished it in larger pieces. Dont leave a straight line though. Always tear a crooked jagged line and try not to overlap a large area . The smaller overlap the better.

I say go for it! I am same way. Scare to try anything new and when i do i usually tweet it and end up saying the heck with it. I found out that if you do mess up or dont like it just take a putty knife, lift a corner of it and it comes right off! Oh and I forgot to mention when you put the pieces on to take something and smooth it out. It pushes all the bubbles and excessive glue out. There is several ways to put the glue on. I used a half and half, sometimes variation of mixture. Sometimes i used a paintbrush to coat the walls and pieces and sometimes i just stuck the paper in the bucket of mixture. One thing I noticed though when i just stuck the whole piece in is because i used a dark color paint it left a slight film which came right off with water but it was extra work so you might not want to do it that way. Just take a paint brush and treat the pieces like you would if you were wallpapering.

Thanks for the old wallpaper idea! My mother-in-law is obsessed with remodeling, so our garage has been collecting dust for years with various materials she bought but didn't use. She also keeps the remains of paints, wallpaper, and construction tools, because she hopes she will still need them. Usually, it doesn’t work like that because if she used something once, then she doesn’t return this purchase anymore. She even stores water-soluble package we introduced into everyday life for the sake of the experiment. Why keep a thing that is so easy to get rid of...?
