If the crack you're filling is deeper than 1/2 in., you must wedge flexible backer rod (available where caulk is sold) into the joint so the caulk is limited to a depth of 3/8 in. The ideal width for a bead is also less than 3/8 in.

A single bead of caulk can fill gaps up to 1/4 inch. If the gap is slightly larger than this, fill it with a bead of caulk deeper into the gap, but not flush with the surface. Wait until the caulk is completely cured before coming back to put a surface bead on.

Should I smooth caulk?

Make sure to squeeze hard enough to force the caulk fully into the joint. Draw the tip of the caulk tube along the length of the joint as you slowly squeeze the handle of the caulk gun, working at a speed that is slow and consistent.
