Smoothing osb sheathing
Making basically a false wall for a project that’s about 6 feet wide and 8 feet high. I made the frame and nailed osb sheathing to it (cheapest option) but now I’m curious how I could get it smooth for paint. I don’t want to buy like 10 things of wood filler and I want to try to stay away from an orbital sander.
Im thinking stick on wallpaper im just worried the texture of the sheathing would be seen when i press the wallpaper on.
Any ideas?
