Apply Caulk to Vertical Exterior Seams

What happens here

Begin applying the caulk to vertical exterior seams, such as those where siding panels meet or around window and door trim. Hold the caulk gun at a consistent 45-degree angle to the joint. Apply steady, even pressure to the trigger while moving the gun smoothly and continuously along the seam. The goal is to create a uniform and continuous bead of caulk that fills the gap completely. The video demonstrates this action on various vertical joints of the house's exterior siding.

Goal: Apply caulk to all vertical exterior gaps
