Diablo's premium 1/3 sheet sandpaper delivers professional-grade sanding for 1/3 sheet orbital pad sanders and hand sanding blocks. Each sheet measures 9" x 3-2/3" - the standard 1/3 sheet format that fits all major brand 1/3 sheet pad sanders.

The 120 grit (medium-fine) abrasive is built for pre-finish smoothing for painted projects, primer prep, and knocking down raised wood grain after the first coat of primer.

• Sheet size: 9" x 3-2/3" (1/3 of a 9" x 11" standard sheet)
• 120 grit (Medium-Fine)
• Premium grain blend formulated for fast material removal and extended sheet life
• Clog-SHIELD coating reduces pitch and resin build-up from softwood and finishes
• ENDURA-BOND grit-to-backing bond resists premature grain shedding
• Compatible with 1/3 sheet orbital pad sanders and hand sanding blocks
• 10 sheets per pack

Tip: For most softwood and painted trim, 120 grit is the right final sanding step before primer. Going finer can partially seal the wood and reduce primer adhesion.
