I cleaned the walls with bleach water then sanded briefly with sandpaper.
Textured Wallpaper in Kitchen
I wanted a easy and frugal update to my kitchen. FYI I just removed the wallpaper and it came right down. It lasted 3 years.
I then wiped all the walls down and dried once more.
I used $14 textured wallpaper from Lowes. I soaked the paper for 30 seconds, then folded together for 5 minutes before placing on the wall. It's called booking and it's to fully activate the glue on the back. I then used a tool to flatten against the wall. I then used a small cutting knife that provided a clean cut on corners.
I love the outcome so far. This wallpaper is textured and can also be painted.
