How to paint exterior door?

Painting an exterior door properly requires a methodical approach to ensure a durable, beautiful finish that can withstand harsh outdoor weather elements. To achieve professional results, it is best to open the door, pop the hinge pins, remove the door entirely, and lay it completely flat across two sturdy sawhorses. Next, use screwdrivers to remove all door handles, locks, deadbolts, and weather-stripping rather than trying to tape around them. Clean the entire door surface using a heavy-duty degreaser like TSP to remove grease and body oils around the handle area. Lightly sand the entire door using 120-grit sandpaper to scuff the old gloss finish, create a profile for adhesion, and wipe away all dust. Apply a high-quality exterior primer, followed by two coats of premium exterior acrylic latex paint using a high-density foam roller for flat areas and a high-quality sash brush for recessed panels.
