Repainting decking and shed

[wong]

I need to repaint my decking and shed.
Decking - Do I need to sand it back? Or just jet wash and repaint with non slip decking paint? Any primer needed?



Shed - Can I just paint over the current paint? or Do I need to sand back, prime, then repaint?

Great. So less work than I originally thought. I might just repaint the lower panels on the shed.
