Have to repaint my MIL porch and floor. what Benjamin moore or SW paint will hold up the best? I am actually doing the whole porch but it is the floor hat concerns me the most.
I agree 100%, I did many a porch floor and concrete as well, with treadplex, been on my basement stairs for last 10 yrs............The most durable paint that I have experience with on porches is SW Armorseal/Treadplex. I painted 200 yards of raw wood bleachers at a local high school a couple of years ago and they still look solid. The only sheens are semi and gloss. This product is undoubtedly one of the most durable paints for a porch or deck.
It's listed at $70 a gallon, if you can get it at 45, it'll be worth it. Talk to your rep and he'll work with you.
