Product Information
Full details
This pack of 10 Makita 40-grit sanding sheets is for professionals and DIYers needing to perform heavy-duty material removal on wood, metal, and painted surfaces with a 1/3 sheet sander. The key benefit is the efficient stripping of paint, varnish, and heavy stock thanks to the coarse 40-grit white aluminum oxide. A potential caveat is that this coarse grit is not suitable for fine finishing and may require subsequent sanding with finer grits.

FAQs
What surfaces can I use these 40-grit sheets on?
These sheets are suitable for heavy sanding and stripping on wood, metal, and painted surfaces.
Can I use these for a smooth finish?
No, 40-grit is a very coarse grade intended for heavy removal. You will need to follow up with finer grit sandpaper (e.g., 80, 120, or higher) for finishing.
How do I know when to change the sanding sheet?
Replace the sheet when you notice a significant decrease in cutting power, the abrasive feels dull, or the sheet becomes heavily clogged with dust and debris.
Are these sheets compatible with random orbital sanders?
No, these are specifically designed for 1/3 sheet orbital sanders. Random orbital sanders typically use round, adhesive-backed or hook-and-loop discs.
What does 'open grain' mean for sanding sheets?
An open grain pattern means there are wider spaces between the abrasive grits. This helps to reduce clogging by allowing dust and debris to escape, maintaining the sheet's cutting efficiency for longer.
What is the grit range for heavy sanding and stripping?
Generally, grits from 40 to 60 are considered coarse and are best suited for heavy sanding and stripping applications.
Troubleshooting
Sanding sheet not staying attached
Ensure the sander's pad is clean and free of debris. Check that the clamping mechanism or hook-and-loop system is functioning correctly and is securely fastened.
Poor material removal
The abrasive may be dull or clogged. Replace the sanding sheet. Ensure you are applying adequate, consistent pressure. Check that the sander is operating at the correct speed and RPM.
Excessive dust despite dust collection
The open grain pattern helps, but heavy material removal naturally creates dust. Ensure your sander's dust port is clear and connected to an effective dust extraction system. Consider using a dust mask rated for fine particles.
Pros and Cons
Pros
- Aggressively removes paint, varnish, and heavy material quickly.
- Durable white aluminum oxide abrasive for extended life.
- Open grain pattern resists loading, maintaining abrasive effectiveness.
- Cost-effective bulk pack for frequent use.
Cons
- Too coarse for any fine finishing applications.
- Requires subsequent sanding with finer grits for smooth surfaces.
- May generate significant dust, requiring appropriate dust collection.
Setup, Compatibility & Care
Setup: Ensure your 1/3 sheet sander is unplugged before attaching or removing sanding sheets. Align the sheet with the sander's pad and secure it firmly using the sander's clamping mechanism or hook-and-loop system, depending on your model.
Compatibility: These sheets are designed for standard 1/3 sheet orbital sanders. Verify your sander model accepts 1/3 sheets.
Care: These are consumable items and are not designed for long-term care. To maximize their lifespan during use, periodically brush off excess dust and debris. Avoid excessive pressure, which can wear the abrasive unevenly. Replace sheets when the abrasive becomes dull or clogged.
