Hello everyone, this is my first post here so aloha lol. I made the mistake of painting door frames, skirting and a bare piece of wood with matt emulsion having done no preparation. I know realise this was a mistake, i have a horrible powdery finish to the skirting and door frames, with regards to the bare piece of wood i realise i also did this all wrong, it still looks like a bare piece of wood but with white paint on it, so what do i do next, how do i recover these mistakes...............
