3M™ Paper Sheet 426U is a general purpose abrasive sanding sheet constructed on an A-weight, light paper backing and features an anti-loading coating and open coat construction. Silicon carbide abrasive and lightweight paper backing make this sheet an ideal product for finishing applications such as paint prep, white wood sanding, sealer sanding, and solid surface finishing.

Easily cut 426U sheet to size for tasks such as sealer sanding with 3M™ Orbital Sander

Fast Cut, Fine Finish on Wood and Painted Metal
3M™ Paper Sheet 426U is a premium silicon carbide sheet that creates a smoother finish than aluminum oxide or garnet abrasive products on painted metal and wood substrates. Its resin bond construction provides superior grain retention while the open coat construction, along with the load resistant coating, combine to provide excellent anti-loading characteristics. The light A-weight backing provides conformability over contours and into crevasses and corners.

Final Finishing by Hand or Power Sander
The sheet can also be easily cut to fit a hand pad block, inline sanders, or finishing or power sanders. Other applications include general sanding, finishing, blending, surface leveling and prep prior to staining or painting. These versatile sanding sheets contain the ideal abrasive grain type and grades for multi-step finishing processes.

A 3M Best for Finishing Hard and Soft Woods
Silicon carbide is a synthetic mineral that is very sharp and commonly used for final finishing in white wood sanding. While it breaks down faster than aluminum oxide, it produces a superior finish.
