How can I smooth out a wall that has been painted with textured paint?

Depending on the type of wall, you may have to do the following additional prep work:





Textured Walls: There are three methods of removing or concealing wall texture.





Floating the Walls: Use a broad knife to trowel the joint compound over the rough walls in light, even coats. After the wall is at the preferred smoothness, allow to dry. Prime the newly smooth surface with 2 coats of primer/sealer.





Sanding: If the texture is minimal and the new wallcovering is heavily-textured, this process is adequate and time-saving. After sanding, a primer/sealer is applied. This method is the least preferred, however, because of the labor and the dust that covers the entire house.





Hang lining paper: Fill all holes and cracks with joint compound, chip off any high points with a broad knife, then lightly sand the wall surface in order to help even out the wall. Prime the wall and allow to dry thoroughly. Using a heavy-duty adhesive, apply to lining paper. Sometimes it really helps to paste both the wall surface and the back of the lining paper since the lining paper is so porous and heavy. Once the lining paper has dried, apply a primer/sealer.





Wood-paneled walls: Wash thoroughly with a deglossing solution and water, then sand smooth. Fill vertical grooves of paneling with spackle and apply primer; or apply primer and hang heavy-duty lining paper. Seal with acrylic or alkyd primer, allow to cure, and hang wallcovering.

Been there, done that, I used an old fashioned carpenters hand plane to knock down the high peaks. It was a knuckle buster though and it will only smooth it out so far. The sanding idea would work after that.How can I smooth out a wall that has been painted with textured paint?
Sand it then put a thick coat of primer.
I wound up using a razor blade scraper. I first sprayed the wall with a light mist of water, and waited about 5 minutes before scraping. God what a mess, but it was better than sanding. Good luck with it. I don't think I will ever use it again. You could always prime it and paint over it or prime it and pick another colored textured paint. Holly
You'll probably have to sand it.If it's not that rough you can wallpaper over it and paint the wallpaper.If you decide to paper do a small test strip to see if you need to size the wall.I always use wall paper paste so it sticks well.
The best way is to use an electric sander with coarse sand paper to prevent clogging....Its quite messy so wear a dust mask.....If you don't like that idea you can mix artex in with your paint and roller over it to fill in some minor cracks and textures....
Score it with a knife and then get it freshly skimmed over by a plasterer, just a finishing skim.
