need to plaster/skim a small section of newly created ceiling in my bathroom. I have no plastering skills at all but want to give it ago. I spotted a large tub of 'Smooth on' in B&Q yesterday. Does anyone know if it is easy to use and what is the best way to approach it. it is onto new plaster board.i knocked down a stud wall in the bathroom to reveal about 6 foot of extra space. I have boxed most of it in as cupborads but the ceiling was not done
