Hanging paintable wallpaper over paneling?
I have successfully done this with rental units. I may have gone overboard but this is what I did. Skimmed the grooves with DuraBond, scuffed the panels with a polesander while feathering the edges of the joint compound. Applied a coat of primer on the panels and joint compound. Read the directions for the wallpaper paste and if they recommend the use of "sizing" (basically a primer for the paste to improve adhesion) use it. Hang the wallpaper, when dry apply primer to the paper (two coats on the seams) the apply the color coat.
