Pool Deck Caulk

[Tomcat]

Wonder what you went with. I need to redo mine.

When first built, I used deck o seal, but I'm not happy with the longevity. After five years or so, it needed repairing. I used a polyurethane caulk (not self leveling) to fill the separation points, but now's it's separated quite a bit more all around the pool.

I just started filling in my decking control joints because they've cracked and separated in some places. The sikaflex SL worked great, was truly self leveling (very fluid), but doesn't come in white unless you buy the two part and mix it. Likewise, I've also used the quickcrete SL and it was fluid, but didn't seem to flow as well as the sikaflex and in fact buckled up as it cured. The sikaflex joint is concave, but the quickcrete joint is convex. Weird. Now I'm going to redo around my coping (over 130 linear ft, yikes!) and am looking at the Vulkem, but it is only semi-self leveling, so I'd like to know how it goes on and cures.
