Understanding the Different Types of Metal Surfaces:
Understanding the different types of metal surfaces is crucial when it comes to sanding metal. Different types of metal surfaces require different sanding techniques and sandpaper grits. Here are some common types of metal surfaces and how to approach sanding them:
|Type of Metal Surface
|Recommended Sanding Technique
|Recommended Sandpaper Grit
|Smooth and Shiny
|These surfaces are already smooth and shiny, such as chrome or stainless steel.
|Use a very fine grit sandpaper, such as 320 or higher, and use a polishing compound for a mirror-like finish.
|320 or higher
|Painted or Coated
|These surfaces have a layer of paint or coating on them.
|Use a medium grit sandpaper, such as 120, to remove the paint or coating. Then switch to a finer grit, such as 220 or higher, to smooth out the surface.
|120, then 220 or higher
|Rough and Rusty
|These surfaces are rough and may have rust or other imperfections.
|Start with a coarse grit sandpaper, such as 60 or 80, to remove the roughness and imperfections. Then work your way up to a finer grit, such as 220 or higher, for a smoother finish.
|60 or 80, then 220 or higher
Types of sandpaper for sanding metal
There are several different types of sandpaper out there, and each kind has a different purpose. The type of sandpaper you choose will depend on what type of project you’re working on and how fine you want your surface to be. Sandpaper can be made with many different materials as well.
Most commonly, it’s made from glass or emery paper, which comes in various grits (fineness). The standard grit sizes are 40, 60, 80, 100, 120, 150, and 180. The higher the number, the finer and smoother your sanded surface will be. You can also find sandpaper coated with aluminum oxide or silicon carbide for use on steel, cast iron, and other hard metals.
Other kinds of sandpaper you must know.
While sanding metal with sandpaper you may need these:
• Sanding blocks:
• Hook-and-loop disc pads:
These discs consist of hook-and-loop fasteners attached to two pieces of sandpaper—one rough side for removing material quickly and one smooth side for finishing work. Many woodworkers like these because they’re easy to use and don’t require any sanding blocks.
• Wet/dry sandpaper:
This sandpaper can be used wet or dry, depending on what you need. It comes in rolls and sheets, but most people prefer sheets because they’re easier to handle when wet.
• Sanding sponges:
Sanding sponges have abrasive particles embedded into their sponge-like texture, acting like sandpaper when rubbed against wood or metal. They’re handy for getting into tight corners where regular sandpaper won’t fit.
• Sanding belts:
Sanding belts are essentially sandpaper glued onto a flexible rubber belt. They’re great for sanding curves and contours on larger pieces of wood or metal. Because sanding belts conform to uneven surfaces, they help you avoid gouging holes in your projects.
• Power sanders:
If you’ve got lots of time on your hands, power sanders can save some elbow grease by doing some work for you. Although more expensive than hand sanders, power tools offer faster results if you’ve got lots of heavy-duty sanding to do. Examples include drum sander attachments for cordless drills and belt sander attachments for electric drills or screwdrivers.

Types of grits for sanding a metal
As you might imagine, many types of grits are available for sanding metal with sandpaper. The type of metalworking project you’re working on and how rough you want your finish will help determine which one is best.
For example, coarser grits may be used to paint while finer ones are meant to finish. Grits range from 60 to 150 depending on the purpose and desired results:
Coarse Grit (60-80)
Use these if you want a super quick cut but don’t want any visible scratches; these work best with alloys that can easily be worked by hand. Because they’re so rough, they will leave significant scratch marks on soft metals like brass, aluminum, and zinc.
Medium Grit (120-180)
These are great for shaping or removing more significant amounts of material quickly. They also tend to leave some scratches behind, so they’re often used as an intermediate step before fine sanding.
Fine Grit (220-400)
These should be your go-to grits if you want your metalwork to have a polished finish. You can still use them for rough shaping or cutting down large amounts of material, but because they create less friction than medium or coarse sandpaper, there won’t be as much heat generated. They’re also great for removing minor scratches left behind by coarser grits.
Ultrafine Grit (600-1000)
These are used only on finished pieces that need extra polishing. Because they remove so little material, it will take longer to achieve a smooth surface, and you might need to apply more pressure than with other types of sandpaper.
Diamond-coated abrasives are ideal for tough metals like titanium and steel that would quickly dull traditional abrasives. They also work well on softer metals like aluminum and brass, although their high cost limits their usefulness in most shops.
Best sanders for sanding metal
The first step in learning How to Sand Metal Faster is knowing which power sander you should use for your project. Several different sanders can be used on metal, but some are better than others, depending on what you’re trying to accomplish and what type of metal you’re working with.
The five best power sanders for sanding down metals include:
- Makita B0630 Random Orbital Sander.
- Milwaukee 2630-20 Random Orbital Sander.
- Bosch 1377L Random Orbital Sander.
- Hitachi SB8V2 Random Orbital Sander.
- Festool 585137EQ Random Orbital Sander.
Each of these sanders has its pros and cons, so you must choose one based on your specific needs. For example, if you need a sander that allows you to work quickly and precisely, choosing a random orbital sander might be ideal.
These sanders typically have smaller orbits than other models, making them great for detailed work or finishing off edges or small areas where other models might struggle. A belt sander might be your best bet if you’re looking for something more powerful or heavy-duty.
These sanders allow users to move large amounts of material quickly without sacrificing accuracy or precision. However, keep in mind that belt sanders aren’t as easy to control as other models and may not be ideal for starting with woodworking projects.
Things to keep in mind when sanding metal with sandpaper
- First, you’ll want to keep in mind that there are several different types of metal. Copper is a softer metal and therefore easier to sand than steel. On an unrelated note, aluminum can oxidize if it comes into contact with oxygen while sanding, so you may want to make sure it is covered when not in use. Steel has various grades, from mild steel (with several varieties) to tool steel and titanium (even more robust than tool steel).
- You’ll also want to consider what you will be using your piece for; if it is exposed regularly and takes a lot of wear and tear, you may need something more substantial like steel or titanium instead of copper or aluminum. If you aren’t sure which type of metal to choose, talk to someone at your local hardware store about which metals would work best for your project.
- They should have experience working with each type and can help you determine which one would work best for your particular needs. Once you know what kind of metal you want to work with, here are some tips on how to get started:
- The first thing you will want to do is make sure that your metal is clean. If it isn’t clean, sanding won’t help because you will simply be removing rust rather than polishing away dents and scratches. After cleaning, use a wire brush to remove any surface contaminants and rough up your piece to have a better grip on the sandpaper.
- You may also want to use an orbital sander (or something similar) to prepare your metal for sanding before switching over to wet-or-dry paper if you are working on a particularly challenging project.
- Wet or dry? There are two main kinds of sandpaper: wet-or-dry, which is explanatory, and garnet paper. Garnet paper comes in different grades depending on how fine you need your finish to be. It is softer than wet-or-dry sandpaper but can also leave behind some residue when misused.
Tips on How to Sand Metal Faster
Some quick tips on How to Sand Metal Faster
- Use a lubricant. Sanding down metal is hard work, so using a lubricant is helpful. Using something like 3-in-1 oil or WD-40 can make your job easier and even provide a thin layer of protection for your skin if you wear gloves. You’ll still want to be careful, but using a lubricant can make your life easier when working with metal.
- Use different types of sandpaper. Not all types of sandpaper are created equal—and some might be better than others at getting rid of unwanted material quickly and effectively, even if they take longer to wear out than their coarser counterparts. For example, if you need to remove paint from an object made of metal, then 80 grit sandpaper will likely do a better job than 100 grit paper. Switch up your techniques.
- If one technique isn’t working as well as you’d hoped, try switching things up. For example, consider moving in circles or other patterns instead of moving in straight lines when sanding down an object made of metal (as most people do). This can help ensure that all parts of an object get equally smoothed out and worn away by your sandpaper before moving onto another area.
- Consider investing in a belt sander. Belt sanders are especially useful when working with metal because they allow you to create smooth surfaces more quickly than traditional hand tools. They also tend to last longer, so you won’t have to replace them as often. Make sure not to apply too much pressure while using one though it can cause burns if misused!
Precautions when sanding a metal
- Wear a dust mask, gloves, and goggles when sanding metal.
- Keep a wet sponge nearby to clean up any mess while you’re working.
- Follow all safety precautions of your power tool while sanding metal.
- Make sure you have adequate ventilation in your workspace.
- Don’t breathe in any fumes from your power tools or chemicals used on metal surfaces.
- When handling metal for sanding purposes, make sure it is dry and clean before using your sander; oil on metal can ruin some types of sandpaper and even damage your sander if left unattended for too long.
- Be careful not to scratch a surface with your sander—this will only cause problems later on down the road.
- Always test out your sandpaper first—don’t assume that because one type works well with wood, it will work well with metal. Metal has different properties than wood, so don’t treat them as interchangeable materials.
- If you are concerned about scratching or damaging a surface while sanding, use an adhesive-backed abrasive pad instead of regular paper. These pads stick directly onto metal surfaces and prevent scratches during use without causing any additional damage over time as regular paper might do.
