I have quite a bit of experience with painting, as I have painted everything from rooms to furniture … and anything else you can think of. I always achieved excellent results, except for one occasion: at that time when I painted the front door of my house. The door in question is metal and receives a good dose of sun in the afternoon. As a result, the metal heats up to oven temperature, and, over time, the paint deteriorates.
After applying the trial and error technique to many base and paint combinations for years, I discovered a successful formula. I tried it last summer on the outer side door of my house, which is also metal and exposed to the sun as much as the main one. No cracks have occurred.
So this spring, I intend to do the same at the front door.
Step 1. How to prepare the door to apply a new coat of paint
If your door has old paint, what you will need to do depends on the state of the paint. If the door finish is free of cracking or peeling, but simply needs a fresh coat of paint, just gently sand the surface and clean it. If the surface paint is cracked or chipped, it will need to be removed with a paint remover or hot air gun. I decided to use a chemical remover. When using a paint remover, it is essential to be careful not to damage the door metal with scratches or indentations. I followed the instructions on the can labels that I had used on previous projects.
It’s a chore and mess job, but it’s a necessary step if you want the new coat of paint to stick to the metal with no problem.
Step 2. Sand and clean
Once all the paint has been removed, sand all areas where the paint has not come off, then wash the door with TSP cleaner and rinse thoroughly. Let dry.
Step 3. Apply foundation
Apply a gripper base coat to the flat surfaces of the door. Use an angled brush to paint any area where there are low relief panels. Let dry.
Step 4. Paint
Coat a light coat of exterior paint on flat door surfaces using a roller. Use the angled brush to paint any area where there is low relief or beveled panels. Let dry.
This is what the door looks like with a light coat of paint on the gray gripper base. Once the first coat dries, add a light second coat of paint and let dry. Make touches if necessary.…
