Where are the aluminium doors and what are you hoping to achieve by covering them?
Are you still wanting to use the doors, or do you want to hide them?
If you mean to repaint your aluminum door, here's a link that might help you:
Hi Erna, what are you trying to do? Can you be more specific. Are you trying to paint the doors, are you trying to cover an aluminum door with curtains? If you are painting aluminum, you can get specific paint for aluminum. I think Sherwin Williams carries a brand specific for aluminum doors. You will want to check with your Sherwin Williams dealer. Don't use latex. Outdoor Rustoleum would also work well.
Sure, good luck!
Do you mean painting them.?
Yes, but if there any other good solution I am open
I would go to a Sherwin Williams store to get paint specifically for aluminum doors. If you want to cover with a medium like contact paper, you will need to clean thoroughly. Other than these 2 ideas, I'm unsure how you would cover a door unless you added some kind of faux panels to it.
