THE FAT BOY SYSTEM – ADVANCED FACE AND SURFACE POLISHING FOR REPAIRS AND BLENDING

Fat Boy 4 inch Sponge Pads are engineered for surface polishing, seam blending, scratch removal, face work and finish restoration on quartz, granite, marble and engineered stone.

Designed for both fabrication shops and in-home repair professionals, Fat Boy Pads deliver precise surface control and a smooth, even finish. They perform the same functions as donkey pads and monkey pads but offer improved durability, more grit options and a larger size lineup.

Quit being a donkey or a monkey. Be a Fat Boy.
Use Fat Boy Sponge Pads.

NEW 15000 GRIT

The Fat Boy system now includes an ultra-fine 15000 grit pad for exceptional clarity and high-end finish quality on both natural and engineered stone.

DESIGNED FOR LOW-WATER AND INDOOR REPAIR WORK

For repairs inside homes or commercial spaces where water must be controlled:

Soak Fat Boy Sponge Pads in water for at least 20 minutes before use.
The sponge absorbs enough water to stay cool and lubricated during polishing without requiring constant water flow.
This allows clean, mess-free repairs in kitchens, bathrooms and tight work areas.
