Ali Indistries Inc 4209 100 Grit Aluminum Oxide Sandpaper 25 Sheets 9x11

100 Grit Aluminum Oxide Sandpaper

This pack contains 25 sheets of 9 x 11 inch sandpaper rated at 100 grit. The medium grade suits surface preparation before painting on wood, metal, plastic or painted surfaces. It is intended for DIYers and tradespeople who need a consistent abrasive for mid-stage finishing work. Buyers who want heavy stock removal or final polishing should choose a different grit.

Resin bond backing and boxed format

A resin coating replaces the ordinary glue bond so the abrasive stays attached longer during hand or block sanding. Sheets are packed 25 to a box, keeping them flat and protected from moisture until needed. The standard dimensions fit common sanding blocks and quarter-sheet palm sanders without trimming. Users who prefer hook-and-loop discs or belt sizes will not be able to use these sheets directly.

Grit 100 decides the job

The single specification that determines fit is the 100 grit rating, which places this paper in the medium range for surface preparation before paint. Coarser grits such as 60 or 80 remove material faster, while finer grits such as 120 or 150 produce a smoother finish for final coats. Select this box only when the project calls for that specific mid-range abrasion level.
