Product Information
Full details
This guide is for DIY enthusiasts and professionals needing to prepare surfaces for finishing. The key benefit is achieving a smooth finish across various materials with durable aluminium oxide sheets. A potential caveat is that 80 grit is a coarser grit, best suited for material removal rather than fine finishing.

FAQs
What does 80 grit mean?
Grit refers to the coarseness of the sandpaper. 80 grit is considered a coarse grit, meaning it has fewer abrasive particles per square inch, making it ideal for removing material quickly.
Can I use this for final finishing?
No, 80 grit is too coarse for final finishing. It is best used for initial shaping, removing old finishes, or preparing surfaces for finer grits. You would typically follow up with grits like 120, 180, and 220 or higher for a smooth finish.
What materials can I sand with these sheets?
These sheets are suitable for sanding most materials, including wood, metal, and some plastics.
How should I store these sanding sheets?
Store the sanding sheets flat in a dry environment to prevent them from curling or becoming damaged.
Can these be used with a power sander?
These sheets are designed primarily for hand sanding or use with a sanding block. While some may be cut to fit certain orbital sanders, they are not pre-cut for power sanders and their durability in powered applications may vary.
How often should I replace a sanding sheet?
Replace the sheet when you notice a significant decrease in its sanding ability, it becomes clogged with dust, or the abrasive particles have worn down. Regular tapping to clear debris can extend its usable life.
Troubleshooting
Sheet clogs quickly
Ensure you are not applying excessive pressure. Tap the sheet frequently to remove dust. For very soft materials, consider a finer grit sandpaper.
Uneven sanding marks
Use a sanding block to ensure even pressure. Move the sandpaper in consistent strokes, either with or against the grain depending on the material and desired outcome, but maintain a uniform direction.
Sheet wears out too fast
Confirm you are using the correct grit for the task. 80 grit is aggressive; for lighter tasks, a finer grit will last longer. Ensure the surface being sanded is free of hard contaminants that can dull the abrasive.
Pros and Cons
Pros
- Durable construction for extended use.
- Effective for initial material removal and surface preparation.
- Works well with manual sanding techniques.
- Good value in a pack of five.
Cons
- 80 grit is a coarse grit, not ideal for final finishing.
- May be too aggressive for delicate materials.
- Requires a sanding block for optimal results on larger areas.
Setup, Compatibility & Care
Setup: These sanding sheets require no setup beyond being ready for immediate use. For hand sanding, simply hold the sheet and rub it against the surface. For more controlled and even sanding, attach the sheet to a sanding block. Ensure the sheet is securely held by the block, either by wrapping it around or using a block with a clamp mechanism.
Compatibility: The 80-grit aluminium oxide sheets are compatible with a wide range of materials including wood, metal, and some plastics. They are suitable for use with standard sanding blocks.
Care: To prolong the life of the sanding sheets, periodically tap them against a hard surface to dislodge dust and debris. If the grit becomes clogged with material, the effectiveness will be reduced. For heavily clogged sheets, consider them used and replace them. Store sheets flat in a dry place to maintain their integrity.
