Caulk between deck and coping?

Hi, Beth,

Did you use acrylic caulk? If so, that was probably the issue. As I indicated above, this Vulkem 911 polyurethane caulk was a complete hassle to work with but it doesn't shrink and forms what appears to be a very, very durable seal. Mine is 2.5 years old and looks like the week I put it down.

I wish I could give you advice on how to get the old caulk out....that's gonna be tough. I would do it mechanically...i.e. no chemicals.

Dave,
We used SIKA Flex (Sikaflex-1CSL) polyurethane caulk, which my dh swears is the same as deck o seal. Its self leveling etc... it was very easy to install, using a caulk gun. But it took some muscles to squeeze it, but it did self level very nicely.
It didn't pull out everywhere just in some places, so I am wondering if we can just cut those piece out and redo only those sections...
The work never stops, we are opening our pool tomorrow.

Beth,

I thought poly would stick to just about anything but apparently not. That's a bummer it didn't hold up well. Patching it in seems like the best solution. Good luck with it.
