Download Article

Rust is an inevitability with metal, but that doesn't make it less shocking when you walk out and run into a hole forming. Whether you're dealing with a small piece of sheet metal or something valuable like a auto, you can fix it. Torso filler is a uncomplicated fashion to repair freshly-cleaned holes. If you know how to weld, take advantage of your tools for a longer-lasting repair. By filling in holes, yous stop rust in its tracks and ensure the metal lasts longer.

1
Put on goggles, gloves, and a grit mask for protection. Protect yourself confronting the rust flakes released while y'all're cleaning the metal. Keep your eyes and oral cavity well-covered at all times. Wear cut-resistant piece of work gloves to guard against abrupt edges. Likewise, complete your outfit with long pants and a long-sleeved shirt.^[1]
- Safe glasses won't fully protect your optics, and so choose goggles instead.
- Dust masks don't completely seal over your mouth. For maximum protection, put on a respirator mask instead.
ii
Work outdoors or in some other well-ventilated surface area. Working outdoors prevents metal dust and other harmful things from lingering in your domicile. Almost projects tin be washed outdoors, including auto or gutter repair. Proceed in mind that you lot will need a place to plug in power tools, or at least an extension cord to connect to the nearest electric outlet. If y'all have to work indoors, practise what you can to ventilate.^[ii]
- For instance, if y'all're indoors, open nearby doors and windows. If you lot take a workshop with a strong ventilation fan, utilise it.
- Keep other people out of the area until you're washed with the repair. Afterward, utilise a vacuum and magnets to eliminate any dust in the air.

3
Cover the surrounding metal with masking newspaper and tape. Cutting some sheets of masking paper to size with a sharp pair of scissors. Press them flat confronting the surface of the metal, and so secure the edges with masking record. Leave the rusted area exposed.^[3]
- Comprehend upwards anything nearby that you lot don't want to become discolored. For example, if y'all're fixing a hole on a automobile, prevent paint or hot sparks from ruining the end.
- Masking paper and tape are bachelor online and at virtually hardware stores. These sources will also have everything else you might demand to make metallic look as good as new.
4
Utilise eighty-grit sandpaper to remove all of the paint and rust. Start with the remaining paint nearly the hole, since it is easier to remove than the rust. To make the repair equally effective as possible, scrub abroad the pigment up to 1 in (ii.v cm) beyond the edges of the hole. And so, go dorsum toward the eye of the pigsty, scrubbing with heavy pressure to eliminate the rust. All of the rust must go. Go on sanding until y'all're able to see bare metallic.^[four]
- This office tin can take awhile, so make things easier past using power tools. For instance, switch to an orbital sander and an angle.
- Yous tin can also use tools similar a flathead screwdriver or tin snips to break off rusty sections of metallic. Rust makes the underlying metal soft and crumbly, and so don't hesitate to cut information technology out.
- Y'all could too use a wire brush to scrub away metal. Use ane for an easier mode to clean rust from the inner role of a hole.
5
Apply a rust primer or converter over the bare metal. These products come up in spray-on or liquid forms, and then the application process will vary a little depending on which i you get. For the spray-on version, hold the canister near 6 in (xv cm) from the clean metal. Point it at the spot, press the push button on tiptop of the tin, then sweep information technology across the bare spot at a deadening merely steady pace. Make sure the entire surface is well-covered with the primer.^[v]
- If you're using a liquid primer, spread it with a cream brush. It'southward like applying whatsoever sort of firm paint.
half-dozen
Wait 24 hours for the primer to get dry to the touch. The primer has to be completely dry to ensure that the repair holds. The exact time required tin can vary from product to product, so be sure to bank check the manufacturer'southward recommendation. If you're working in cold or humid weather, expect the primer to dry out at a slower charge per unit.^[6]
- Later on the primer has finished drying, inspect it to ensure the metal looks fix. If it's still exposed, rust could set in once again and cause more than problems. It's worth recoating the spot a second time to ensure it stays clean.
- If you're recoating the metal with additional layers of primers, you may not need to expect the unabridged 24 hours. Some products let you employ additional coatings within an hr.

1
Select a patch matching the type of metallic you lot're repairing. If you're using a metal patch, information technology should be the same type of metal. For example, zinc patches work very well on cars, since most are made with zinc-coated steel. For other objects, such equally aluminum gutters, use an aluminum patch instead. The best way to become what you need is by purchasing a repair kit containing the patch and an agglutinative.^[7]
- If you're unsure what kind of patch to utilise, get a fiberglass patch. It'due south a general-purpose cloth that bonds well to any type of metal.
- If you match the wrong metals together, one of them will corrode over fourth dimension, so you volition be left with a piece of metallic needing to be patched all over once again.
2
Trim the mesh with scissors so it fits over the hole. Keep the patch about one in (2.5 cm) longer on all sides than you think yous need. Y'all can ever trim it down more later if it's as well big for the pigsty. Sharp scissors are fine for well-nigh cases, but switch to tin snips if you're having trouble cutting through the textile. Make the patch roughly the aforementioned shape equally the hole as well.^[8]
- To size the patch, yous could tape a piece of wax paper over the hole, then trace the shape of the hole with a permanent marker. Employ the tracing as a template to cut an identical patch.
- It is possible to use several layers of patching material. Layer several fiberglass patches, for case, to level out a deep hole and make the repair stronger.
iii
Mix body filler with a paint stick on a scrap piece of cardboard. Apply the stick to scoop a golf game ball-sized dollop of the torso filler out onto the cardboard. Open the divide harder and spread 5 to 8 drops of it beyond the body filler. Then, stir the body filler until information technology'south well-mixed. It will plow a compatible color, usually dark-green, although it varies depending on the color of the body filler and hardener.^[9]
- If you're using a fiberglass patch, mix a fiberglass resin and hardener together. The mixing procedure is the same as it is with body filler, so nada changes!
- The filler and hardener typically come up packaged together in a kit. If you're buying them separately, make sure you lot have both products.
iv
Insert the metallic patch behind the hole. Accomplish underneath the metal if you're able to, or button the patch through the pigsty. And then, spread the patch out so it'due south apartment confronting the remaining metal. The patch should completely cover the hole. Keep it stuck in place by spreading a petty bit of the body filler around its edges.^[x]
- Getting the patch in identify can be tricky. Attempt spreading some filler around inside the hole with a paint stirrer. Alternatively, you lot might be able to pin the patch in place with magnets.
- If yous can't get a patch to stick, consider using an epoxy filler instead. Epoxy filler is like a putty, so all you have to do is spread information technology flat on a piece of fiberglass mesh glued over the pigsty. Information technology's a simpler mode to repair a hole, only it doesn't last as long as a patch.
5
Cover the patch with a coating of body filler. Well-nigh kits come with a plastic applicator you can utilize to spread the filler. If you don't accept one, use a paint stick. Apply enough of the filler so it's about ¹⁄₄ in (0.64 cm) higher than the surrounding metallic.^[xi]
- You can sand down the filler later and so it's even with the surrounding metal and ready for repainting. If information technology doesn't look not bad now, no worries. It doesn't have to.
six
Wait about 1 hour for the filler to completely dry. Body filler dries rapidly, and then you won't have to wait long. Exist sure to check the manufacturer'southward instructions for the precise drying fourth dimension. One time the filler is hard to the touch, y'all can brainstorm blending it in with the old metal.^[12]
- The patch dries out faster when it'southward in an area with good air circulation. During cold or humid days, expect it to dry out out a little slower than normal.
- One time the initial layer dries, you tin can apply more filler if it is needed to level out the surface or even finish filling in an oddly-shaped expanse. Sand the patch with 80-dust sandpaper before each coating.
7
Sand the patch smoothen with 180-dust sandpaper. Scrub the entire patch with a calorie-free merely firm amount of pressure. Sand the entire patch until it's level and feels polish to the touch on. Use a lighter touch around the edges to blend the patch in well without scratching the metallic around information technology.^[thirteen]
- Wipe off any dust on the patch before painting it. Yous can use a tack cloth or a microfiber cloth dampened in warm water.
8
Spray on a paint primer and let it dry for ane hour. To quickly paint over the patch, get a quick-drying spray-on primer designed for metal surfaces. Shake the can, then hold it about 6 in (fifteen cm) from the patch surface. While spraying the primer, sweep the canister from side to side across the patch. Don't overlap your strokes as y'all movement from left to correct, or else the paint could build up unevenly in certain spots.^[fourteen]
- Painting at the right speed can be a trivial tough if you have never used spray-on paint or primer before. Practice on a piece of scrap material first, like cardboard.
- Make certain the primer is completely dry to the touch before painting over it. The patch should besides be covered. If information technology's still exposed, it could rust, and then even information technology out with a 2d glaze of the primer.
9
Pigment over the primer and let it dry out for 24 hours. If you lot're going for a more professional person terminate, select a spray-on pigment that all-time matches the color of the existing metal. Hold the canister half dozen in (xv cm) from the surface and apply it from left to right across the patch. Make sure the coating is consistent. If it isn't, let it dry, so use boosted coating every bit needed to restore the metal back to normal.^[15]
- Doing this is great for hiding damage on a car, just y'all don't have to exercise it for things like unpainted metal gutters.

one
Trace an outline of the pigsty on a piece of wax paper. Wax paper is slightly transparent, so information technology'southward a sneaky fashion to go a good idea of what you need to patch over the hole. Hold the paper flat against the metal, then outline the hole with a permanent marker. Cut out the template with pair of scissors afterward.^[16]
- Brand certain the outline is accurate. Cutting it a piffling bigger than the bodily hole is fine. If it doesn't cover the hole, remake it.
2
Use metal-cutting shears to cut a copper bankroll. Identify the template over a copper canvass. Have a permanent mark and describe around the outline. Make the bankroll the aforementioned size as the hole. So, trim it out and set it bated.
- Some other tools you tin can use include can snips, a hacksaw, or a dremel.
- Hardware stores generally have everything yous need for the repair, including welding fabric and copper sheets. Cheque online as well for anything you can't find in a store.
iii
Attach the copper panel to the back of the pigsty with a clamp. Reach underneath the hole to install the copper panel, if possible. You're going to need a way to go along information technology at that place while yous're welding. Try plumbing equipment a clamp around the metallic and copper panel to bind them together. If you're unable to become a clamp in place, employ a welder's magnet instead by placing it on top of the metal.^[17]
- Make sure the copper backing is the same size as the hole. The edges should exist accessible, or else you won't be able to weld them to the existing metal.
4
Put on a welding mask and other gear to protect yourself. Wearable a shaded welding mask to protect your optics against the light from the welding torch. Besides, put on heat-resistant welding gloves and an apron. Have a fire extinguisher nearby likewise.^[18]
- Piece of work abroad from combustible surfaces. If you're fixing sheet metal, place information technology on a welding table, for case.
- Remember to work in a well-ventilated expanse! Accept other people stay out until you're done.
five
Install a steel wire into the torch of a MIG welder. Since steel won't stick to wire, it's perfect for filling in the holes around the copper. Feed information technology through the tip of the torch, making sure information technology stays centered. If it feels like it's stuck, pull it out, clean it, and recenter information technology.
- Wipe the wire make clean with a dry fabric. If it gets muddy, the weld won't plough out very strong.^[19]
- For an inexpensive, all-purpose choice, get a AWS ER70S-3 steel wire. Employ AWS ER70S-6 steel wires for a higher-quality repair.
6
Connect the welder to its gas tank and exposed metal. Hook the hose adapter to the outlet on top of the gas tank. The hose is on the back of the MIG welder, well-nigh where y'all installed the steel wire. After securing the gas, walk to the front of the car and take the other black hose in that location. This one will accept a metal clamp at the end. Secure it to a welding table or a bare console on a car, for instance^[twenty]
- Shielding gas is used to protect the hot metal so it cools into a strong weld. Try using 100% carbon dioxide for an inexpensive way to complete about projects. A 75% argon, 25% carbon dioxide mix volition also work, and is great for welding tough metals like steel.
- The grounding clamp is for safety. Information technology lets out electricity, especially when something happens that causes the welder to overload.
seven
Spot weld every 3 to 4 in (7.6 to 10.2 cm) along the metal. Turn on the welder, and then concord the torch at a 90-degree bending to the metal. Bring the tip of the torch right up against the metal. Hold it there for a couple of seconds to place a ⁱ⁄₂ in (1.3 cm) wide spot of melted steel wire. Do this all the way effectually the perimeter of where the existing metal and copper bankroll meet.^[21]
- Remember to remove your clench or magnet subsequently the initial few welds cool. They will concord the metal together while you finish the repair.
- If the pigsty is small, y'all can close it just past spot welding. You won't need to apply a bronze backing. The steel from the torch's wire will fill in the hole.
viii
Add together more spot welds to fill in the remaining gaps between the metal. Go back to the get-go spot you made. In one case it is cool, weld another spot next to information technology. Complete more ⁱ⁄₂ in (1.three cm) welds side by side to the original set you made. Echo this until the entire perimeter is filled.^[22]
- Spot weld adjacent to each of the cooled spots. Position your torch so the spots don't overlap at all.
- This is called stitch welding since it isn't one continuous weld. Instead, y'all will end up with a bunch of metal dots, kind of like US dimes, next to one some other.
nine
Sand the weld flat with a metallic angle grinder or Dremel tool. Endeavour using an bending grinder fit with an abrasive flap wheel, for instance. Await at to the lowest degree 30 seconds for the weld to end cooling, then hold the wheel upwards to each spot. Grind them all downwards until they're smooth and roughly level with the surrounding metallic.^[23]
- Sanding the weld makes it look much amend. It's skilful if you plan on masking the weld, but you should always do it if you desire to paint over it.
10
Prime and paint the metallic to give it a more than professional look. If you're planning on roofing over the welded spot, utilize a chemical compound, such as a body filler. Cover the entire copper backing, along with the weld, using a woods paint stick. After it finishes drying, level it out with 180-grit sandpaper, then spray on a primer. Apply a coat of pigment afterward if you wish to lucifer the repair to the existing metallic.^[24]
- At the very least, cover the weld and apply a primer to seal out rust. Fresh welds are vulnerable to rust, especially before they have had a chance to absurd.
