Steam and moisture resistance

Dave had today off work, which admittedly I thought meant Xbox day. I was surprised to come home to find he'd been to B&Q and come back with a multitude of goodies and surpassed my expectations of his DIY skills! Oh, and he had my dinner on the table when I got in too. I, on the other hand, waltzed in, dumped my wet clothes, ate the food then sat in my pjs all night. The closest thing I got to DIY was popping my head round the door to take this photo... and in doing so, might have accidentally got paint all over the lens of my camera. I think I'm in trouble. I'm trying to make it better with an offering of builder's tea.
