If your garage door needs some TLC, today, we’re going to show you how to prep and paint your garage door.
We’re going to focus on metal garage doors in this article. We have another article about painting wooden garage doors, though.
We’re going to show you how to prep the garage door for paint, repair any damages and the best paint and practices to use while painting it.
So, let’s find out how to paint a metal garage door, shall we?
You can employ a high-quality chemical paint stripper to remove old paint from your garage door.
Alternatively, you can use medium to fine-grit sandpaper, depending on the number of paint layers your garage door has accumulated. If you opt for a chemical stripper, it’s essential to sand the door’s surface afterwards to ensure the complete removal of the old paint.
We suggest investing in an affordable sander for this task. Not only will it expedite this process, but you’ll also find the sander useful for numerous other projects.
After removing all the paint, it’s time to prepare the surface. If there’s any rust on the door, now is the moment to address it.
There are discs specifically designed for angle grinders that can efficiently handle surface rust. Alternatively, you can purchase metal paint that can be applied directly over rust. However, if the rust on your metal garage door is severe, you might need to replace parts of the door or even the entire door.
If you intend to prime and paint your metal garage door a few days after you have stripped the paint off, you should cover it to protect it from the elements. If you don’t, it will rust.
Once you’re ready to paint, wipe the metal down and remove any dust, dirt and grime. You can use white spirit to ensure all of the dust has been removed. Now is the perfect time to mask off any areas you don’t want paint on, too. Use good-quality masking tape and paper to protect the garage and other surfaces.
Before painting, apply a high-quality metal primer to the garage door. Most metal primers offer excellent rust protection, ensuring your garage door remains protected for years.
Adhere to the instructions provided on the primer can; some may necessitate sanding between coats, while others might require sanding before painting. Once the metal primer is completely dry, you can proceed with your chosen paint.
For optimal results, apply thin coats and follow the guidelines on the paint can. Thin applications prevent dripping and allow the paint to dry faster. Most metal paints typically need at least two coats for thorough coverage, with some demanding three or more.
That’s how you paint a metal garage door. The process isn’t overly complicated.
With thorough prep work, ensuring the removal of as much old paint as possible and cleaning the door to eliminate dust, the painting becomes straightforward. But which paint is best for a metal garage door? Let’s delve into paint options, shall we?
