The Diablo DCS120080P01W is a 12 in. x 18 in. 80-grit sanding sheet with StickFast PSA backing, designed for moderate stock removal and surface preparation on wood using drum and wide-belt sanders. This is a floor and large-surface sanding sheet built for professionals who need a reliable, long-lasting abrasive that keeps cutting rather than glazing over mid-job.

The abrasive layer uses a premium aluminum oxide blend - a formulation chosen specifically because aluminum oxide fractures during use, continuously exposing fresh, sharp cutting edges. The result is consistent material removal from the first pass to the last, without the drop-off in performance you get from cheaper abrasives. The 80-grit rating places this squarely in medium territory: aggressive enough to flatten rough surfaces and remove old finishes, refined enough to leave a surface ready for a finer follow-up grit before top coat.

Diablo's ENDURA-BOND resin system anchors the aluminum oxide grit to the backing with a high-strength bond that resists the heat and friction generated during extended sanding sessions. Grit shedding is one of the main failure modes for cheap sanding sheets - the ENDURA-BOND system addresses that directly, keeping the abrasive where it belongs throughout the life of the sheet.

The Clog-Shield stearate coating on the face of the sheet acts as a release layer between the abrasive and the material being sanded. Pitch, resin, and wood fibers that would normally pack into the grit and kill cutting performance are shed off the surface instead. For contractors working with pine, fir, or any resinous softwood, this coating makes a measurable difference in how many passes you get before the sheet needs replacing.

The StickFast backing is an industrial-grade pressure sensitive adhesive (PSA) system. Peel and press - the sheet bonds firmly to the sanding drum or plate without clips, clamps, or water activation. When the sheet is spent, it peels off cleanly without leaving adhesive residue behind. This is the attachment system specified for use with the Clarke-American OBS22 drum sander, among other machines that use PSA-style sheet attachment.

This sheet is the right choice for finish carpenters, flooring contractors, and woodworkers doing surface prep before staining or coating - anyone who needs to knock down high spots, remove old coatings, or flatten a surface efficiently before stepping up to a finer grit. At 80 grit, it is not a finishing sheet; use it as a working pass before moving to 100 or 120 to close the grain for finish work.

A No-Nonsense Workhorse Sheet for Real Sanding Jobs

The Diablo DCS120080P01W delivers on the basics that matter most in a sanding sheet: it cuts aggressively, resists clogging, and holds together through the full life of the sheet.

• Who it's for: Flooring contractors and woodworkers using a Clarke-American OBS22 or similar PSA drum sander who need a dependable 80-grit sheet for stock removal and prep work before finishing.
• Why it stands out: The combination of ENDURA-BOND resin bonding and the Clog-Shield stearate coating means this sheet keeps cutting longer than a standard aluminum oxide sheet - less downtime swapping abrasives, more consistent surface quality across a large area.
• Worth knowing: This is sold as a single sheet - stock up if you have a big floor or wide surface project, since 80-grit prep work burns through abrasives faster than finish grits.

• What machines does this sheet fit? This sheet is specified for use with PSA-compatible drum and wide-belt sanders, including the Clarke-American OBS22. Check that your machine accepts PSA-backed 12 in. x 18 in. sheets before ordering.
• What materials can this sheet be used on? Diablo rates this sheet for use on wood. It is designed for moderate stock removal and surface preparation prior to coating or finishing.
• Is 80 grit right for my project? 80 grit is a working grit - use it to remove old finishes, flatten uneven surfaces, or take down rough stock. It is not a finishing grit. Plan to follow up with 100 or 120 grit before applying any stain or topcoat.
• How do I attach and remove the sheet? The StickFast PSA backing peels and sticks directly to a compatible sanding drum or plate. Press firmly to seat it, and peel it off when the sheet is spent. No water, clamps, or clips required.
