80 Grit Medium Abrasive Sheets
Ali Industries 4210 aluminium oxide sandpaper comes in 9 by 11 inch sheets for surface preparation before painting. The resin coating resists wear better than standard glue bond paper. Each box contains 25 sheets suitable for wood, metal, plastic and previously painted surfaces. This medium grade balances material removal with a smooth finish.
Resin Bond Construction and Sheet Format
The resin coating extends abrasive life during hand sanding or block use. Standard 9 by 11 inch dimensions fit common sanding blocks and half sheet orbital sanders without trimming. Aluminium oxide grain stays sharp across wood, metal and plastic substrates. The 25 sheet pack supports multiple project stages from a single box.
Not for Heavy Stock Removal or Fine Finishing
Builders needing aggressive stock removal should choose a coarser grit such as 60 grade. Projects requiring ultra smooth surfaces between polyurethane coats need finer grades like 150 or 180. Check that your sander accepts 9 by 11 inch sheets or half sheet formats before ordering. Verify the medium 80 grit matches the specific surface preparation stage required.

Questions about this item
What grit level does the 80-grit aluminum oxide sandpaper provide for surface preparation?
The 80-grit grade is rated Medium and is intended for surface preparation before painting on wood, metal, plastic and painted surfaces.
What are the sheet dimensions and how many sheets come in a box?
Each sheet measures 9 inches by 11 inches and the box contains 25 sheets.
How do you attach the sheets to a hand sander and what mistake should be avoided?
Cut or fold the 9x11-inch sheet to fit the sander’s clamp size and secure it tightly; the common error is leaving the sheet loose, which causes tearing and uneven sanding.
