What happens here

Address any areas with pre-existing chipping paint. Use 80 to 120 grit sandpaper (either by hand or with an orbital sander) to effectively remove all loose paint flakes. Focus on smoothing out the transition between the raw wood or substrate and the old, intact paint to create a seamless surface. Once sanding is complete, apply a water-based primer specifically to these repaired areas. Allow the primer to dry completely according to the manufacturer's instructions before proceeding with the main paint application.

Goal: Prepare chipped areas for new paint.
