Wallpaper

What burb man said. Paperhanging is a lost art lol. They used to have a sizing paint they used before hanging wallpaper. I have no clue what traditional unpasted wallpaper is. They make diffrent kinds of wall paper. Paper backed vinyl, paper backed paper, vinyal backed vinyl, Foil backed vinyl, etc , etc I would use the vinyl backed vinyl, its one peice of solid vinyl. More money but easier to wash , clean and remove. I have never wall papered a camper. And i haven't hung wallpaper in 25 years. I dont know what they use for pastes now. Clay was always good, but not with certian papers. Wheat would mold, but that stuff never came off, the clear used to be garbage.
