A polyurethane "porch and deck" paint would be a logical choice.
Glidden makes one, Home Depot carries it, I use it...shop floor, steel
French doors opening to screen porch and lanai...a counter top on the screen
porch...any place where I want a hard, durable surface. The colors
available are limited. I use white which yellows a bit after a couple of
years but not so much that I mind it. Green mold will grow on it too if it
is where it is frequently damp; if so, add some mildewcide.
Using solid stain. Steer clear of Cabots, absolutely the worst in the
industry IMO. Applied BM's Arborcoat solid almost a year ago, so don't
know what the long term durability is, yet. Cabot's started peeling on all
the flat surfaces within a month. What of waste of $600.00!
