We've got 2 walls painted with a suede effect paint that has a rough texture but now we'd like to paint over it. It's not as rough as artexing so I'm looking for something I can paint over it to smooth it out before painting again. Ideally it will be something I can apply with a brush rather than a scraper. I don't really want to sand it down either as it'll be a pain and seriously eat into my daily gaming time! Anyone point me in the right direction as to what I can use on it?
