š ļø About These 70x100mm Wet & Dry Sponge Sanding Sheets
Built for the weekend warrior and the professional detailer, these 70x100mm hook-and-loop sponge sanding sheets bridge the gap between aggressive material removal and mirrorālike finishing. Whether youāre knocking down body filler on a restoration project, leveling a hardwood surface before staining, or wet sanding clear coat to remove orange peel, the flexible foam core hugs curves and contours that rigid paper simply canāt follow. The premium aluminum oxide grain stays sharp longer and rinses clean when loaded, so you work faster with less dust. Hook-and-loop backing means you peel, press, and go ā no clamps, no wasted time.

ā Common Questions About 70x100mm Wet Dry Sanding Sheets
Can I really use these sanding sheets with water?
Yes, absolutely. Every sheet uses a waterproof resin over the abrasive and a closedācell foam body that wonāt absorb moisture. Wet sanding dramatically cuts dust, keeps the abrasive from clogging, and yields a smoother surface on automotive clear coats, gelcoat, and highāgloss finishes. Just dip in a bucket, keep the surface wet, and rinse the sponge frequently.
Will these fit my sander? What brands are compatible?
They fit any random orbital or palm sander that uses a 70x100mm hookāandāloop pad ā which is one of the most common sizes. Many owners of DeWalt DWE6401, DWE6421, Makita BO5041, Bosch ROS20VSC, Ryobi, and Wen orbital sanders use these sponge sheets successfully. Always measure your platen: as long as itās approximately 2ā3/4" x 4", youāre good to go. The loop backing grips securely without any additional adapter.
How do I tell the grits apart? Are they marked?
Each sponge sheet is printed with its grit number on the reverse side (the nonāabrasive backing). The coarse ones (300ā400) feel aggressively rough to the touch, medium (600ā800) feel like coarse paper, fine (1000ā1200) begin to feel smooth, and very fine (1500ā2000) feel almost slick. If ever in doubt, start with what feels least aggressive and work downward until the scratch pattern matches your needs.
How long does one sheet last compared to regular paper and sandpaper?
Because the foam sandwich absorbs vibration and the grain is bonded to a flexible, tearāresistant base, these sponge sheets typically outlast standard paper discs 2ā3 times under similar pressure. When performance drops, simply rinse the sponge in water to dislodge packed dust and let it air dry. The abrasive stays sharp through many cleaning cycles, making them a costāeffective choice for large projects.
Are these suitable for automotive paint correction and detailing?
They are widely used by DIY auto body enthusiasts for this exact purpose. Use 300ā400 grit for heavy filler shaping, 600ā800 to level primer, and 1000ā2000 grit wet to refine clear coat before compounding and polishing. When you progress through the grits, you remove previous scratch patterns and leave a nearāpolished surface that buffs to a mirror finish with minimal rotary work.
Do the sheets leave pigtails or deep scratches?
When used correctly ā moving steadily, not dwelling in one spot, and stepping through the grits from low to high ā these aluminum oxide sponges produce a consistent scratch pattern that gets finer with each pass. Avoid jumping from 300 straight to 1500; use the intermediate grits, and the deep scratches will be completely erased by the time you reach 2000 grit, leaving a uniform haze ready for polishing.
