We have an old IP (late 60s) with wallpaper in one of the bedrooms. Our old tenants very kindly painted another bedroom before moving out, but left the wallpapered room, which is looking tired. I know it's preferable to remove the wallpaper rather than paint over it, but the interior walls are fibro-masonite, so contain asbestos. As it's interstate, we had a handyman quote for the work; he suggested painting over the wallpaper as he didn't want to remove it with the bare wall underneath. The wallpaper's in fairly good condition - just paint over it given the fibro-masonite?
