PEEL, ALIGN, AND PRESS ONTO A PSA PAD
Use a full-contact adhesive disc where a no-hole pattern fits the process
PSA means pressure-sensitive adhesive. The sticky backing attaches directly to a clean compatible pad, while the uninterrupted abrasive face provides full-surface contact.
16 live variants
Both diameters are listed in 80, 100, 120, 150, 180, 220, 320, and 400 grit.

DECISION GUIDE
Which PSA disc size and grit should you choose?
Fit the diameter to the backing pad and choose grit from the current scratch pattern, the work material, and the finish or coating manufacturer’s preparation requirements.
Compact pad coverage
Choose only for a compatible 5-inch PSA backing pad that does not require an extraction-hole pattern.
More surface coverage per pass
Choose for a compatible 6-inch PSA pad and larger-panel work.
Correction through pre-finish sanding
Use 80–100 for faster leveling, then 120–180 as progressively finer stages when the workpiece and finish schedule call for them.
Fine refinement and coating preparation
Use for fine scratch refinement or approved between-stage preparation. Do not assume every stain, primer, or coating should be sanded to the finest available grit.
ORIGINAL PRODUCT SPECIFICATIONS, RETAINED
What exactly is in each PSA disc box?
Aluminum oxide on paper backing
The product record specifies a premium C-weight paper backing with a resin bond and an anti-static top coat intended to resist loading.
Pressure-sensitive adhesive
Remove the release liner and press the sticky-back disc onto a clean compatible PSA pad.
No-hole, full abrasive face
There are no extraction holes. Do not use where the pad or dust-control system requires an aligned hole pattern.
100 discs in one size and grit
Choose 5-inch or 6-inch and one of eight live grits from 80 through 400.
PSA DISC COMPATIBILITY
Are sticky-back discs the same as hook-and-loop discs?
No. PSA discs bond to a smooth adhesive-compatible pad; hook-and-loop discs attach mechanically to a separate hook-face pad.
Presses directly onto a PSA pad
Peel the release liner, center the disc, and press the full face onto a clean compatible pad. Do not add a hook-and-loop interface between the disc and pad.
Does not align with through-pad vacuum holes
The solid abrasive face covers any holes in the pad. Use a no-hole setup only when the tool and dust-control method are appropriate for it.
Diameter and attachment must both match
A 5-inch or 6-inch random orbital, dual-action, rotary, platen, or stationary disc sander still needs the correct PSA backing pad and an approved speed range.
Clean, flat contact supports secure attachment
Dust, oil, old adhesive, edge damage, or an uneven pad can prevent full contact. Stop and inspect the pad if a correctly sized disc curls or lifts.
PROJECT-BASED GRIT GUIDE
Which PSA sanding-disc grit should you start with?
Begin with the least aggressive grit that removes the current defect, then refine that scratch in controlled steps. The required endpoint depends on the substrate and the next coating or finishing operation.
Faster leveling and coating removal
Use for more aggressive dry sanding when the workpiece and tool can tolerate the scratch. Follow with the intermediate grit needed to remove it.
Intermediate sanding and pre-finish preparation
Use to reduce coarser scratches, blend repairs, and prepare wood or metal for a specified next step.
Fine surface refinement
Use where the finish schedule calls for a finer scratch before primer, sealer, paint, or another finishing stage.
Very fine preparation and scratch reduction
Use only when the substrate and coating instructions call for this range. Sanding wood too fine can change stain or finish absorption.
Loading note: The anti-static top coat is intended to resist loading, but no paper disc is clog-proof in every finish, resin, pressure, or heat condition. Replace a loaded disc and correct the process rather than forcing it.
HOW TO USE IT
Attach the disc to a clean PSA backing pad
Pad condition, alignment, rated speed, pressure, heat, and dust control affect disc retention and the finished scratch pattern.
- 01
Disconnect power or remove the battery and confirm disc diameter and PSA attachment.
- 02
Clean and inspect the backing pad; replace a damaged or contaminated pad.
- 03
Peel the release liner, center the disc, and press the full face firmly into place.
- 04
Follow the tool instructions for starting and stopping; verify that the disc runs flat, stays centered, and remains secure.
- 05
Sand with controlled movement and replace a loaded, torn, curled, overheated, or lifting disc. Stop to inspect the pad if lifting repeats.
Use the guarding, extraction or collection, personal protective equipment, training, and operating procedures required by the machine, abrasive product, work material, and workplace.
Use it for
- Compatible 5-inch or 6-inch PSA backing pads
- Wood sanding and finish preparation
- Ferrous alloys and other metals with an approved process
- Sanding, deburring, blending, and finishing
- Shops that consume boxes of 100 in one size and grit
Do not use it for
- Hook-and-loop backing pads
- A pad or vacuum setup that requires extraction holes
- A dirty, oily, damaged, or incompatible backing pad
- Use above the disc or tool speed rating
- Wet sanding unless the abrasive specification, backing pad, tool, and complete process are approved for it
PRODUCT FAQ
Questions before you choose?
What does PSA mean?
PSA means pressure-sensitive adhesive. PSA, adhesive-back, and sticky-back are common names for discs that use a release liner and press directly onto a compatible PSA backing pad.
How many discs come in a box?
Each selected variant is a box of 100 discs in one diameter and one grit.
Do these discs have dust-extraction holes?
No. These are no-hole discs. They block through-pad extraction and should be used only where the tool, pad, and dust-control process are appropriate for a solid disc.
Can these discs be used on metal?
The current product record lists aluminum oxide discs for wood, ferrous alloys, and other metals in sanding, deburring, blending, and finishing work. Validate the complete process for the material.
Will these fit a random orbital sander?
Only if the sander has a compatible PSA backing pad in the selected diameter and does not require a particular extraction-hole pattern. These are not hook-and-loop discs.
Can I wet sand with these PSA paper discs?
Do not assume these discs are suitable for wet sanding. The current product record does not identify the backing as waterproof, so use them dry unless Maverick confirms the selected disc and the tool, pad, and process are all approved for wet use.
