Exterior Caulking | Master Sealing Your Home To Paint

What happens here

Move to the vertical corner boards. Apply caulk along the seams where the corner boards meet the siding. Ensure a continuous, smooth bead, working slowly to allow the caulk to fill any deep gaps. Next, identify any visible nail heads on the siding and trim. Pay particular attention to nail heads that are not flush with the surface or those that have penetrated the siding too deeply, as these can take on water and swell, potentially voiding siding warranties. Apply a small amount of caulk over each nail head and smooth it with a gloved finger to seal it completely. The caulk over the nail heads will be painted over and will not be visible.

Goal: Apply caulk to vertical corner boards and all visible nail heads, especially those that are not flush or have penetrated the siding.
