How Many Grades of Scuffing Pads Are There and Which Applications Are They Suitable For?
In industrial work, surface preparation is a crucial step that directly affects the quality of the next processes, whether painting, coating, deburring, or assembly. If the wrong abrasive tool is selected, problems such as uneven surface, peeling paint, blistering, or rework may occur, leading to higher production costs and longer production time.
One of the most widely used surface preparation tools in factories is the Scuffing Pad, also commonly called non-woven abrasive pads. Scuffing Pads from Norton are especially popular because they come in several models and different levels of coarseness and fineness, allowing users to match them to each production step.
Common questions include:
- How many grades do Scuffing Pads have?
- Which grade is suitable for which job?
- Which model should be selected for each production line?
This article explains in detail to help you choose the right pad accurately and cost-effectively.
What are Scuffing Pads?
Scuffing Pads are abrasive pads made from non-woven synthetic fibers combined with high-quality abrasive grains. They are designed for:
- surface preparation before painting
- deburring edges of workpieces
- removing surface gloss or contaminants
- blending scratches from coarse sanding
- final finishing and defect removal
Key advantages of Scuffing Pads
- produce consistent scratch patterns
- easy to control
- minimal base-material removal flexible and able to reach corners and contours
- suitable for both wet and dry applications
What materials can Scuffing Pads be used on?
Scuffing Pads can be applied to many materials, including:
- steel
- stainless steel
- aluminum
- plastic
- fiberglass
- automotive parts
This makes them suitable for automotive parts manufacturing, industrial painting facilities, maintenance work, and metal furniture production.
How Many Grades of Scuffing Pads Are There?
Generally, Scuffing Pads are classified according to coarseness and fineness, similar to sandpaper:
- lower grit number = coarser, stronger cutting action
- higher grit number = finer, finishing work
For industrial applications, Norton Scuffing Pads commonly used in factories come in four main grades below.
1. Coarse Grade – Norton 440 (#150)
✔ Finishing characteristics
- aggressive cutting power
- clearly visible scratch pattern
- opens the surface quickly
- suitable for heavy-duty work
✔ Suitable for
- removing old paint
- rust removal
- eliminating heavy contamination
- opening surface to improve coating adhesion
✔ Industrial applications
- plant maintenance work
- metalworking and machining shops
Norton 440 (#150) is ideal when strong cutting force and fast surface removal are required at the first stage of preparation.
2. Medium Grade – Norton 496 (#280)
✔ Finishing characteristics
- medium aggressiveness
- smooth and controllable scratch pattern
- does not excessively remove base material
✔ Suitable for
- surface preparation before painting
- deburring cut edges of metal
- blending marks from coarse sanding
✔ Industrial applications
- metal painting factories
- automotive parts production
- OEM production lines
Norton 496 (#280) is a popular and versatile grade because it covers both surface preparation and intermediate finishing.
3. Fine Grade – Norton 447C (#320)
✔ Finishing characteristics
- fine and uniform scratch pattern
- smooth finished appearance
- does not damage the substrate
✔ Suitable for
- high-quality paint preparation
- finishing before clear coating or lacquer
- applications requiring smooth cosmetic surfaces
✔ Industrial applications
- industrial painting jobs
- decorative stainless-steel finishing
- electrical appliances and visible components
Norton 447C (#320) improves paint adhesion while keeping scratch marks from appearing after coating.
4. Ultra-fine Grade – Norton 447 (#400)
✔ Finishing characteristics
- very smooth surface
- scratches are barely visible
- used for final finishing steps
✔ Suitable for
- finishing before product delivery
- parts requiring strict QC inspection
- last-stage defect removal
✔ Industrial applications
- cosmetic surface finishing
- premium-grade painting processes
- components where product appearance is critical
Norton 447 (#400) is ideal for achieving highly uniform and flawless surface quality, minimizing defects at the final production stage.
How to Select the Right Scuffing Pad for Your Production Line
You can choose the right Scuffing Pad easily based on the working step:
heavy paint removal / heavy rust
➜ Norton 440
general surface preparation before painting
➜ Norton 496
high-quality finishing surface preparation
➜ Norton 447C
final finishing before product delivery
➜ Norton 447
Selecting the correct grade from the beginning helps:
- reduce working time
- lower rework rate
- minimize surface defects
- improve product quality standards
