Sanding Peeling Paint and Edges

What happens here

Using an Ekasant electric orbital sander equipped with a coarse grit sanding sponge, aggressively sand all areas of the door jamb where the primer is peeling. Pay close attention to removing all loose and flaking paint to ensure a smooth, stable surface for subsequent coats. Then, switch to a half-inch foam abrasive to carefully sand contoured and rounded edges, achieving a smooth transition and preparing these areas for painting.
