Caulking the Door Frame

What happens here

After the first coat of primer has dried, the presenter applies caulk to seal any remaining gaps around the door frame. He uses 'Big Stretch' caulk, which is designed to be flexible and durable for exterior use. He carefully applies a bead of caulk into the seams between the door frame and the siding. To achieve a smooth, professional finish, he immediately smooths the freshly applied caulk with a wet sponge, wiping away any excess.

Goal: Seal gaps and cracks for weatherproofing and a smooth finish
