| Tool/Material | Description |
|---|---|
| Sanding Paper | Various grit levels, such as 80, 120, 180, and 220 grit |

Preparation
Before you start sanding, it’s important to prepare the metal door properly. Here are some key steps to follow:
-
Remove any hardware, such as handles, hinges, and door knockers, to ensure they’re not damaged during the sanding process.
-
Use a wire brush to remove rust and loose paint from the surface. This will help the sandpaper work more effectively.
-
Wipe down the door with a damp cloth to remove any dust or debris.
-
Apply masking tape to any areas you don’t want to sand or paint, such as window panes or decorative elements.
-
Set up drop cloths to protect floors and furniture from paint and dust.
The Sanding Process
Now that your metal door is prepared, it’s time to start sanding. Here’s a step-by-step guide:
-
Start with a coarse grit sandpaper, such as 80 or 120 grit, to remove any remaining rust or loose paint.
-
Use a sanding block to hold the sandpaper and apply even pressure while sanding. Avoid pressing too hard, as this can damage the metal surface.
-
Work in small sections, following the grain of the metal. Sanding against the grain can cause scratches and damage the surface.
-
After sanding with the coarse grit, switch to a finer grit, such as 180 or 220 grit, to smooth out the surface and prepare it for painting or refinishing.
-
Repeat the sanding process, gradually moving to finer grits, until the surface is smooth and free of scratches.
Painting or Refinishing
Once your metal door is sanded and smooth, it’s time to apply primer and paint or finish. Here’s how to do it:
-
Apply a coat of primer to the metal door, following the manufacturer’s instructions. This
