How to Repair Armored Door Rust

Did you know that armored doors can rust? And, when they do rust, it can be a real pain to repair them. This blog post will show you how to repair armored door rust so your door looks as good as new. Stay tuned!

How to Repair Armored Door Rust

Repairing armored door rust is important because it can help keep your door looking new and in good condition. If you don’t fix the rust, it can eventually cause more damage to the door, which can end up costing you more money in the long run. So, make sure to repair any rust as soon as you notice it!

Summary: If you have an armored door, you know how important it is to keep it in good condition. Unfortunately, even the best doors can start to show signs of wear and tear over time. If you’re experiencing rust on your armored door, here’s how to fix it! First, you’ll need to remove any rust that’s causing the issue. This can be done with a wire brush or a rust removal compound. Once the rust is gone, you can apply a new coat of paint or sealant to the door. Make sure to wait until the door is completely dry before using it again.

Things You’ll Need

  • Steel wool
  • Grease
  • Patience

Place steel wool in the ungreased pot. Heat steel wool on low heat to avoid charring or burning it. Add grease and let soak. Mix the two ingredients, scraping them up with a metal utensil like a spoon to get all of the pieces onto the bottom of the pan. Clumps tend to stick ;). 

Scrub the door with an even coat of oil, then generously apply oil to the door’s rust areas with your hands or cloth rag (do not use dry). For heavily rusted spots, reapply oil; be persistent; keep at it! Repeat the process each time you see new rust appear on the surface over the next few days.

A Stepwise Guide on How to Repair Armored Door Rust

Step 1:  Disassembly

To repair an armored door’s rust, you will need to disassemble the entire unit. Be sure to remove all screws and bolts before prying it apart. In most cases, these metal parts are joined together by an adhesive and a metallic strip. You will need to remove all of these before proceeding.

Once you have removed all the fasteners, the door will come apart quickly and without too much noise. Now that you have the door apart, you can see the extent of the rust damage and how it has eaten through all those parts.

Step 2:  Cleaning

Once you have disassembled your armored door, it is time to clean everything thoroughly. There may be dirt and old grease in the crevices. These will prevent a solid adhesion of the paint and rust preventatives you use later. Clean everything as well as possible with some hot water and a clean cloth (no soap or solvent; they may dissolve some of the grease, which is not what you want). Make sure to dry everything off before proceeding.

Step 3:  Repairing the Rusty Parts

Now that your door is clean, it is time to repair some rust. There are many ways how you can go about doing this. First, you can either spot-repair or sandblast all the rusty areas and then repair them individually. A third method is to use a combination of both.

Spot repair is a method of repairing small areas of damage on metal surfaces. The advantage of spot repair is that it does not require any preparation, and you can start painting immediately after doing the repair. The disadvantage of spot repair is that if you allow rust to sit for too long, it may spread through the metal and damage other parts as well.

Sandblasting is a good way to remove rust en mass without compromising the underlying metal. However, it does require some preparation, and you will need to use some filler first. It also takes longer to prepare everything for painting.

Step 4:  Remove Rust with Electrical Current

This is another possible method how to removing rust from sheets of metal. This method requires a direct electrical current, which you will run through the sheet metal to make the oxidation process work faster. You can either use a small generator or an old car battery for this purpose, but keep in mind that doing it with the latter may be dangerous if you are unsure how to do it safely.

Step 5:  Rust Removal

Removing rust can be done in two ways: using a rust converter or sanding it off. A rust converter will turn the rust into magnetite, while sanding it off will remove the rust completely. Each method has its own advantages and disadvantages.

Using a rust converter is very simple and straightforward: You paint everything with the solution and wait for it to dry. However, the rust converter will only work when it finds metal not covered with lacquer or paint. This means you would have to disassemble your armored door entirely and do some sanding in between the metal parts before you can use a rust converter. And even then, there are no guarantees how long the reaction will last.

Sanding, on the other hand, is more time-consuming and arduous. However, you can use it even if some paint layers are covering your metal parts (although rust converters may not be able to convert the old rust under such conditions). If you do sand everything down first, make sure you go down to the bare metal. You will have to use some wonderful sandpaper, ideally 1000 or above.

Step 6: Sanding

When repairing armored door rust, you will have to use some form of sanding equipment. This is how the paint will stick to the metal surface better. Make sure that you choose a coarse type of paper or pad so it will remove all those little divots and dents left by the rust before you apply the filler.

Step 7:  Rust Protection

After you’ve removed all the rust from your armored door, it’s time for the next step: rust protection through painting. It may seem odd to spend all that time removing rust only to apply paint for protection, but it’s necessary to remove all the rust quickly in order to effectively repair the door.

If you use high-quality paint from one of the professional-grade manufacturers, your solution will last years without any problem – even without applying for any further protection. However, if you are looking for how to repair armored door rust to save money, you can also use automotive primers or rust converters followed by paint.

Step 8:  Reassembly

Once the rust protection is applied and dried up completely (which takes about one day), it is time to reassemble your armored door. This step is easy to do after you have finished sanding down the metal parts. However, if you have some rust, it may be wise to check how well they are protected by applying some primer on top of them before reassembling everything. This way, you ensure your doors will be resistant to rust for at least another year.
