I have a old deck that I'm gonna pressure wash, well 2 of my friends said to "paint it" and then my cousin (contractor) said paint would eventually ROT the wood, he said to "stain it again"....What say you?
Don't paint it, don't stain it..........
I have seen several painted decks with 20 plus years on them. How many painted porches do you suppose there are? My daughter's deck is painted, about 15 years old now and no rot. She's getting ready to paint it again. It's not cracked or peeling. Place I re-habbed in N Georgia had a 25 year old painted porch in good condition.
I am NOT recommending paint over stain just passing on some personal experience. I would lean towards stain myself, BTW never paint your wood sided house.
