Our subject matter is my sister's countertops, see where the cracking/crumbling is? Water will get in there, it just, does. SO, tape the perimeter so you can get a nice finished edge when you are done. Leave enough room for the caulk to fill the edge, but not look like a huge line of caulk. Ya want it to be there, but not THERE.
Squirt a line of caulk along the joint. Wet your finger and press the caulk into the join smoothing it out a bit. Have some paper towels on hand to wipe off the excess.
Then, while it's still wet, remove the painters tape and marvel at your beautiful caulk line!
It's a nice little winter project, ya know, while we are stuck in this vortex of frigid weather, why not seal up our house a bit!
