In my experience, this caulk does not shrink and it does not crack.
I am too finicky about my projects to rely on someone else’s prep and finish work, so I’ve tried every caulk under the sun. In my experience, they all crack eventually. But about a year ago, my painter friend recommended Sherwin Williams SherMax caulk.
Keep in mind that I am never caulking an area over 1⁄8 in., and generally I am only caulking a paper-thin gap between two materials, so I can’t say how well it holds up on large gaps. But in my experience, this caulk does not shrink and it does not crack.
SherMax is not quite as easy to work with as some other latex caulks that I’ve used. It can pull a bit if you’re not careful. To prevent pulling, I lick my finger before striking the caulk line. I also wear gloves or have a bucket of water for cleaning my hands before it dries because this caulk is super tough and does not come off easily.
