My pool deck area is what I believe is stamped concrete. Every 4 months it keeps getting so dirty that I have to pressure wash it to clean it. See pic. I believe part of the problem is that the surface is extremely porous.
What can I do to mitigate this problem? I have few ideas but not sure if they’ll work.
Hose it down every other week.
Paint with concrete sealer/wet look. Though it’s VERY porous.
