Edited by Tayyaba Rehman — By Fiza Rafique — Updated on May 4, 2024
Abrading refers to the general process of wearing away a surface by friction, while sanding specifically uses sandpaper or other abrasive materials to smooth or finish surfaces.

Key Differences
Abrading is a broader term that encompasses any method of scraping or wearing away a surface through mechanical action, often involving various tools or techniques. In contrast, sanding is a specific type of abrading that uses sandpaper or sanding tools to smooth or modify surfaces, typically wood, metal, or plastic.
The purpose of abrading can vary from removing old paint or rust, preparing surfaces for further treatment, or creating a specific texture. On the other hand, sanding is primarily used to prepare surfaces for painting or varnishing, or to remove imperfections and achieve a desired smoothness.
Abrading can be achieved through different means, such as using a grinding wheel, abrasive blasting, or filing. Whereas sanding specifically involves the movement of abrasive materials (like sandpaper) back and forth across the surface.
The tools involved in abrading can range from manual files and grinders to powered devices like orbital sanders and belt sanders. Sanding tools, however, are generally limited to sandpaper (both manual and powered sandpaper tools), which may vary in grit size depending on the smoothness required.
In terms of finish, abrading may not necessarily result in a smooth surface; it often leaves a rough finish depending on the method used. Sanding, in contrast, is usually intended to leave a surface smooth and is often followed by additional finishing processes.

Common Curiosities
Why is sanding important in woodworking?
Sanding is crucial in woodworking to smooth out rough edges and prepare surfaces for finishing treatments like painting or staining.
What is the difference between sanding and polishing?
Sanding prepares a surface by smoothing it, while polishing is a finer process that creates a shiny, smooth finish.
What does it mean to abrade a surface?
To abrade a surface means to wear it down through mechanical action such as rubbing or scraping.
Are there different types of sandpaper for sanding?
Yes, sandpapers come in various grit sizes, from coarse to very fine, to suit different stages of the sanding process and different materials.
What kind of surface finish does sanding leave?
Sanding generally leaves a smooth finish, suitable for painting or applying other finishes.
Can abrading affect the structural integrity of materials?
Excessive abrading can remove material and potentially weaken structures, so it should be done carefully.
Can abrading be done without specialized tools?
Yes, abrading can be achieved with simple tools like sandpaper or even naturally abrasive materials, though specialized tools are often used for efficiency.
Can all surfaces be sanded?
Most surfaces can be sanded, but some materials require specific types of sandpaper or techniques.
Is abrading necessary before painting metal?
Yes, abrading metal by sanding or other methods is important to remove old finishes and ensure good adhesion for new paint.
How does abrading differ from chemical etching?
Abrading physically removes material through friction, while chemical etching uses chemicals to dissolve or wear away material.
Can you abrade metal?
Yes, metal can be abraded using techniques like grinding, filing, or sandblasting to remove rust, paint, or to prepare the surface for coating.
What safety precautions are necessary for sanding?
Safety goggles, dust masks, and proper ventilation are necessary to protect against dust and particles during sanding.
How do I choose the right sandpaper for a project?
Choose sandpaper based on the material and the desired finish; start with a coarser grit and move to finer grits for a smooth finish.
What is a common mistake when sanding wood?
A common mistake is using too coarse a sandpaper initially, which can create deep scratches that are difficult to remove later.
What are the environmental considerations with sanding?
Dust from sanding can be harmful if inhaled and should be managed with dust extraction systems or by sanding wet to minimize airborne particles.
