Would love to see a picture of your fathers floorMy father painted his garage workshop floor for many of the above reasons, but also because it's much easier to sweep a painted surface than a raw concrete one. The dust from the latter is awful. Dad was a notorious miser though, so any old leftover paint would do for him, resulting in a tastelessly multi-coloured surface. Pragmatic though and he wasn't bothered about what others thought as no one else resorted to his workshop domain, apart from mum who would bring him a cuppa. He was also quite eccentric and once painted a pair of work trousers black because he didn't like the colour. Hardly a fashion victim and he was most annoyed that using gloss paint on a pair of trousers would make them go "all hard and uncomfortable". He was a civil engineer! There truly is no such thing as "common" sense - it's a rare attribute.
