I have three back steps which are under a overhang, but they do get
spattered when it rains. They are pine over treated lumber and SWMBO
wants the pine removed and something like TREX laid over them. I saw
some hardiboard siding (?) which looks like 3/8 thick and yellow in
color. Would this be acceptable if screwed down every 12 inches?
Will it hold paint? How about wear and weather resistance? I've
never used it but have used the grey cement board.

TIA
