That is something I've been wondering, if you have planed wood to clean it up, dimension it etc, what is a good way to roughen the surface?

Thanks @sreilly but my interest in roughening after planing is for a different application, the treads of spiral cat stairs lol. No problem if someone doesn't have a solution here, I can start a thread about it, just thought I'd ask after it was mentioned above.
