Black & Decker 80G MOUSE 5-pack sandpaper

I reach for 80‑grit sheets when I need to remove material decisively—old finish on a window sash, a stubborn paint edge on trim, or rounding over a rough cut that a saw left behind. Black & Decker’s Mouse 80‑grit sheets are built for those exact jobs: coarse stock removal in tight quarters. After running a few projects with this 5‑pack, I’ve got a clear sense of where these sheets shine and where they fall short.

Setup and fit

These are sized for Mouse‑style detail sanders, with perforations that line up to the tool’s dust ports and a pointed nose for getting into corners. Fit on my pad was straightforward: align the holes, press down from heel to tip, and you’re in business. The replaceable tip is the standout detail. The nose is where the abrasive wears out first, so having a spare tip to swap in extends the life of the sheet meaningfully. I’ve learned to keep a couple of those tips in my apron pocket; they’re small and easy to misplace.

One caveat: if you bear down hard or tilt the pad on an edge, the sheet’s tip can lift. Keeping the pad flat and pressure light prevents that. Before each swap, I also brush dust out of the sander’s pad hooks and the sheet backing—clean hooks grab better and reduce any tendency for a corner to peel.

Abrasive performance

As an 80‑grit aluminum oxide, the cut is exactly what you’d expect: fast, coarse, and controlled. On softwoods like pine and poplar, I could erase mill marks quickly without scorching. On painted trim, the sheets removed flaking paint and feathered hard edges well. They are aggressive enough to level wood filler flush without smearing it.

Aluminum oxide is a tough, friable abrasive that fractures under load to expose fresh cutting edges. In practice, that means the sheets keep cutting at a consistent rate until they load up. On resinous knots or gummy latex paint, they will clog; a quick pass with a crepe‑rubber cleaning block restores some bite and extends life.

You’ll want to follow with finer grits for finish work. After using these Mouse sheets, I typically step to 120 and then 180 before primer or clear finish. If you stop at 80, you’ll see scratch patterns telegraph through paint, especially under glossier finishes.

Dust collection

The perforations do their job as long as you align them with the pad’s holes. With the sander’s onboard collection engaged, dust capture is noticeably better than non‑perforated sheets. On interior trim where I care about cleanup, this matters. It’s not a dust‑free experience, but it keeps the surface clear enough that the abrasive isn’t skating on debris. If you have the option to connect the sander to a vac, extraction improves further and keeps the grit cutting sharper for longer.

Tip: before sticking on a new sheet, knock dust out of the pad holes with compressed air or a brush. Clogged holes reduce airflow and shorten sheet life.

Durability and lifespan

These are consumables, and 80‑grit gets used hard. On bare pine and poplar, one sheet’s main body lasted through several door casings and a pair of window stools if I rotated to fresh areas and swapped the tip when it dulled. On old, layered paint with the occasional nail kiss, life drops fast—as it will for any 80‑grit detail sheet.

The replaceable nose helps balance the wear pattern. The tip dulls first because that’s where most users naturally concentrate pressure. Swapping keeps the central area cutting longer and makes the 5‑pack go further. If you push down, the abrasive overheats, glaze forms, and your usable life shrinks. Light pressure and steady movement are the keys; let the grit do the work.

Control and surface quality

On delicate trim profiles, control is where the Mouse format and these sheets really earn their keep. The pointed nose gets into tight corners and narrow recesses that a quarter‑sheet sander can’t reach. The contour sheets flex enough to ride a slight radius or the inside of a cove, so I could blend patch work without flattening the profile. You still have to be mindful: 80‑grit erases material quickly. A couple extra seconds in one spot will flatten a bead or round over a sharp reveal. I treat these like a shaping tool and sneak up on the final surface.

The backing feels compliant without being floppy, which helps maintain contact over uneven profiles. Scalloping is minimal if you keep a consistent pace and avoid pivoting on the tip.

Where it shines

• Small to medium detail work: casings, sashes, furniture edges, drawer fronts
• Paint prep on profiles where larger sanders can’t reach
• Feathering repair areas to blend patch and original
• Fast material removal with decent control in corners

Where it struggles

• Large flat fields: door slabs, tabletops, deck boards (you’ll go through sheets quickly)
• Gummy coatings and resinous knots without frequent cleaning
• Heavy pressure or aggressive angles can cause the tip to lift

If your project is a whole room of baseboard or a set of cabinet doors, a larger sander with bigger sheets or discs will be more efficient and cheaper per square foot. Use the Mouse sheets for the edges, corners, and inside profiles after the big surfaces are handled.

Tips for best results

• Use light, even pressure. You’ll remove material faster, keep the surface flatter, and extend sheet life.
• Align the dust holes and clean the pad between changes to maintain good airflow and adhesion.
• Start with 80 only when you need it, then step through 120/180 to erase scratches.
• Rotate the sheet on the pad to use fresh areas; swap the replaceable tip as soon as it dulls.
• Keep a crepe cleaning block nearby to clear loading on paint or resin.
• Mark high spots with a pencil; stop as soon as the line disappears to avoid over‑sanding.

Value and pack size

You get five sheets in the pack, each with a replaceable tip and dedicated contour options. For household repairs, touch‑ups, or a furniture refresh, a single pack covers a surprising amount of ground if you use it efficiently. If you’re tackling a full exterior door with multiple layers of paint, plan on more than one pack, or complement with a bigger sander for the flat fields.

I appreciate that the sheets are consistent from one to the next—no surprises in cut rate or backing quality. That predictability matters when you’re blending patches or matching surfaces across a room.

The bottom line

These Mouse 80‑grit sheets do exactly what they’re designed to do: remove material quickly in tight spots while maintaining good control, with useful dust perforations and a clever replaceable tip to stretch their life. They’re not a miracle worker for big jobs, and they demand a light touch to stay put and avoid digging in. Used correctly, they cut cleanly, clear dust well enough, and help you get into corners and contours without ruining profiles.

Recommendation: I recommend these sheets for anyone using a Mouse‑style detail sander on small to medium tasks—paint prep on trim, furniture edges, window sashes, and corner work where precision matters. They’re a practical, well‑thought‑out consumable with features that genuinely help in detail sanding. If your work is mostly large flats or heavy stripping, you’ll save time and money using a larger sander for the bulk removal and reserving these for the areas only a Mouse can reach.
