Start by preparing the metal door for painting. Remove any hardware such as doorknobs, handles, or hinges using a screwdriver if necessary.
Thoroughly clean the door to remove dirt, dust, grease, or any other contaminants that could affect paint adhesion.
Using medium-grit sandpaper, lightly sand the metal door’s surface. This step helps create a rough texture for better paint adhesion.
To ensure a clean surface, use a tack cloth to wipe away any sanding dust. The tack cloth will pick up fine particles and leave the surface ready for priming.
Using a synthetic bristle or foam brush, apply a coat of primer suitable for metal surfaces. Begin by painting the recessed or detailed areas first, then move on to the larger flat surfaces.
Now it’s time to paint the metal door. Stir the exterior paint thoroughly with a paint stirrer. Use a synthetic bristle or foam brush to paint the recessed or detailed areas first, followed by the larger flat surfaces.
Depending on the desired color and coverage, you may need to apply additional coats of paint. Allow each coat to dry according to the manufacturer’s instructions before applying the next one.
Once the final coat of paint has dried, reattach the hardware to the door using a screwdriver. Take care not to scratch the freshly painted surface.
Properly dispose of any used paint cans, brushes, or other materials according to your local regulations.
