Jonathan - Bit of a daft question. My partner is a control freak. She's just painted the bedroom in her house with all furniture bedding etc in place and refuses to use any coverings or dustsheets. Uses a brush, so less splatter than a roller, and claims she doesn't need to cover anything because she doesn't ever make a mistake. I explained no professional or good amateur would do likewise. Could you please point me to a professional 'how to' guide, college training material, or even write a few sentences yourself about good practice and decorating. READ MORE…
I am not aware of any training material about this since it should be common sense that there are always going to be random splashes and risk of spillage - accidents do happen.
However, if your partner is happy to continue not to use dust sheets then the best thing to do is not interfere, she is bound to have a mishap at some stage and will learn the hard way.
This video sprang to mind, btw
