I had a lot of trouble stripping the wallpaper off the main wall in my laundry which left some indentations in the wall. I filled these but have found afer sanding the wall and painting the undercoat that quite a few of the marks are still showing. Can you please suggest a technic that will cover the marks in the wall and won't cost a lot as I can't afford much more. Is there a textured roller? or something that will give the wall texture?
