I have a concrete shed but the door is wooden (and currently painted blue - think it has been painted with perhaps an exterior gloss). I have a tin of Cuprinol garden shades in the colour black but would I definitely have to remove all of the previous paint or could I just roughly sand it down? If it's going to be quite a time-consuming job, would it be easier to just use a black exterior gloss on the door - if I use one of those, do I have to remove all of the blue paint or can I just sand it down roughly first? Any advice would be appreciated. Thank you.
