FAQs

What is Grit 80 sandpaper best used for?

Grit 80 is considered a medium grit, ideal for aggressive stock removal, shaping, and initial smoothing of wood and paint. It's perfect for removing old finishes or smoothing rough surfaces before moving to finer grits.

Can I use this sandpaper on metal?

While primarily intended for wood and paint, the hard aluminum oxide grain can provide some material removal on metal surfaces for general grinding or preparation tasks. However, specialized metal abrasives may be more effective for dedicated metalwork.

How long should this sanding sheet last?

The lifespan depends on the application and user technique. The C420's special bond strength contributes to high durability and reduced grit loss, extending its service life compared to standard sandpaper, especially when used within its intended applications.

What does 'C/D paper back' mean?

This refers to the type and weight of the paper backing. 'C' weight is generally for medium-duty applications, and 'D' weight is for heavier-duty tasks. The combination suggests a durable yet flexible backing suitable for contour sanding.

Can I use this with a random orbital sander?

Yes, if your random orbital sander uses a clamping system to attach sandpaper sheets (rather than hook-and-loop), this sheet is compatible. Many tools designed for sheet paper are compatible.

What are the dimensions of this sanding sheet?

The dimensions are 230 mm in width and 280 mm in height.

Does this sheet come in other grits?

Yes, the Bosch C420 line is available in other grits, such as G100 and G120, for finer finishing tasks. This specific product is Grit 80.

Troubleshooting

Sanding sheet tears or breaks prematurely

Ensure the sheet is securely clamped and not overtightened. Check for sharp edges or debris on the sanding pad. Reduce excessive pressure during sanding.

Uneven sanding results

Verify the sanding sheet is applied flat and evenly on the tool. Ensure consistent pressure and movement across the surface. Check that the surface being sanded is also relatively flat.

Dust collection is poor

Ensure your sander's dust port is clear and connected properly to a dust extraction system. The sandpaper itself does not have holes for dust extraction.
