A rusty door or door frame is a problem that, if left alone, can turn into something really serious. Appearance aside, if not repaired quickly enough, rust will progress to permanent metal degradation over time. Then the only way out will be to replace the damaged elements. Meanwhile, self-repair is not, contrary to appearances, a difficult challenge and does not require ordering a specialist each time. In this guide, you will learn how to renovate a rusty metal door without incurring additional costs?
Even if you’re new to do-it-yourself home improvement projects, painting rusting accessories or patio furniture doesn’t have to be as scary as it sounds. Each item is different, so follow the steps below to do it properly and efficiently. Here are some professional tricks for painting rusting metal.
How to paint a rusty metal door?
Step 1: Check for structural damage to the metal
Check the size of the rust. If it’s just superficial rust that easily degreases with a light touch, the paint will stick better. But if the rust is deeper, you may need to consider replacing it. If the rusting area is too pliable or malleable, it is too late to paint. Regardless of the quality of the primer and paint, if the metal is rusting beyond the irreparable point, it is better to replace it.
Step 2: Scrape off excess rust
Before you start applying primer and paint to the door or doorframe, you need to remove all rust and start with a clean surface. Otherwise, the new coat of paint will have an uneven surface and risk of flaking again. Effective rust removal tools include wire brushes and sandpaper. Gently run a wire brush over the rust a few times until all of it comes off. Then rinse the area with warm water and wipe with a soft cloth to get rid of any excess dirt and grease that may remain from the rust.
Tip: You can make your own rust degreasing solution by mixing a mild dishwashing liquid with water. Apply it to the rust and then let it air dry before applying the primer.
Step 3: Use a quality primer before painting
In order for the paint to adhere to the metal after removing the rust, a quality primer is key. Rinse the area with water and let it dry. Then completely cover and protect the area with an oily metal primer. These types of sleepers are readily available at any hardware store.
Step 4: Apply paint
Depending on your style, painting over rust can take on a variety of looks and textures. When using a paint spray on rust, you’ll get a more uniform texture than when using a standard brush. Spray painting allows for a more consistent and professional result. It also works great to cover any spot in hard-to-reach areas.
Rusty metal door – when not to paint?
Always inspect rust thoroughly before painting. If a piece of metal is too badly rusted, no amount of preparation and primer will bring it back to life. Make sure the rusting metal is strong enough to do the job – whether it’s a piece of garden furniture or an iron gate you’re refinishing.
