I had a gap between the concrete and the fiberglass stairs in pool. Bought polyurethene caulk today and applied and tooled it with alcohol like I do all my caulks. Man the thing was hard to squeeze out with the gun, the hardest I ever worked with. When I was done it looked great and seems like it will hold up at least 10 years. Did anybody else use something different? I don't want to use silicone, as it's just too soft and pliable and won't stand up to traffic.
