Description

🔧 Precision Dry Sanding for Fine Finishes — A4 Dry Sandpaper P280–P1200, 230mm x 280mm. Engineered specifically for dry applications where controlled, consistent scratch patterns matter most. These full‑size A4 sheets feature a sharp aluminum oxide abrasive that cuts efficiently through paint, primer, metal, wood, and composite surfaces without water or lubricants. The medium‑fine to fine grit range from P280 to P1200 makes them particularly well‑suited for surface leveling, between‑coat sanding, and pre‑polish preparation on automotive bodywork, furniture, and industrial components. With 50 sheets per pack, they provide the volume professional workshops and busy DIYers need to keep projects moving without constantly restocking.

❓ Frequently Asked Questions

💧 Can I use these sheets for wet sanding?
These sheets are designed specifically for dry sanding. The paper backing is not waterproof and will soften or deteriorate if used with water or lubricants. For wet sanding applications, please use our silicon carbide waterproof sheets available separately.
📏 Which grit should I choose for sanding between coats of paint?
P600–P800 is ideal for light sanding between coats of primer or paint. For final smoothing before clear coat, use P1000–P1200 for a fine, even surface that promotes adhesion without visible scratches.
🧾 Do the 50‑sheet packs come in a single grit or mixed?
Each pack contains 50 sheets of a single grit. Select your desired grit from the options. We recommend keeping a selection of grits on hand—P320, P600, and P1000 cover most common dry sanding tasks.
📐 Can I cut these A4 sheets to fit my orbital sander?
Yes. The A4 size can be easily cut or trimmed with scissors to fit a variety of orbital sanders, detail sanders, and custom hand blocks. The paper backing cuts cleanly without excessive fraying.
🛡️ Will these sheets clog during dry sanding of painted surfaces?
The aluminum oxide abrasive resists loading under normal dry sanding conditions. For best results, use light to moderate pressure and replace the sheet when it shows signs of clogging or reduced cutting performance.
Pro tip: For the best finish when dry sanding, work through grits progressively and use light, even pressure. A tack cloth between grits removes surface dust and helps prevent cross‑contamination scratches.
