Scrape away loose or flaking paint and damaged material with a putty knife.
Use a wire brush to remove any remaining loose particles from the crack area.
Allow the wall to dry completely before proceeding to prevent trapping moisture.
Use a utility knife to widen hairline cracks slightly for better filler adhesion.
Apply exterior-grade filler into the crack using a putty knife, pressing firmly.

Let the filler cure fully as per the product instructions before sanding.
Sand the patched area lightly to create a smooth, even surface.
Wipe away dust with a damp cloth and allow the area to dry again.
Apply a coat of exterior primer over the patched area using a paintbrush.
Let the primer dry completely before applying caulk or paint.
