Seal and Secure Vertical Joints

What happens here

Once the trim board is initially fastened, focus on sealing the vertical joints where trim pieces meet or where they abut another surface. Apply a continuous bead of Christy's Red Hot Vinyl caulk directly into the joint, ensuring full coverage. Immediately after applying the caulk, use a finger to smooth the bead into the joint, creating a clean, professional seam that provides excellent weatherproofing. If nails were driven proud, use a hammer to gently set them slightly below the surface.

Goal: Caulk and finish vertical seams for weather protection and aesthetic appeal.
