What is self leveling caulk?
Self-leveling is just what it sounds like. It is a thinner material and will flow to fill up the gap between your concrete slabs nicely. It finishes with a nice surface and doesn't require any smoothing afterward. However, self-leveling caulk can run out through the ends of a crack, or through any gaps underneath where you caulk. So you must make sure you've got a pretty well-sealed area for the caulk before you put it down. It cannot be used on any vertical surface either. Typically, if your job is larger, self-leveling caulk is the way to go as it doesn't require smoothing.
What is non sag caulk?
