Hello, I have a set of outdoor steps that are in need of a little care and attention after years out in the elements. There are 2 coats of paint that have worn through, and the brown undercoat is some sort of rubberised protective paint layer which is currently not providing much protection. There is also a small area where the timber has rotted that I suspect will need cutting out and filling. What are the appropriate steps and materials for this painting and repair job? Before repainting should I strip the current back to the bare wood or can I paint over the existing paint after sanding? Any advice gratefully received to bring these steps back to a good condition. Thanks in advance.
