3M 7000126424 Wetordry Sanding Sheets 400A Grit

Product Description

The 3M 7000126424 is a wet-or-dry abrasive sanding sheet designed for finish-coat sanding work on painted, varnished, and primed surfaces. Each sheet measures 9 inches x 11 inches and carries a 400A grit rating, making it suitable for fine material removal between successive finish coats without cutting too aggressively into the underlying layer. The sheets can be used wet with water to reduce abrasive clogging and extend usable sheet life, or used dry depending on the application. Sold in a Pro-Pak multi-sheet format, this product is sized for standard hand-sanding blocks and palm sanders common in finishing work.

These sanding sheets are used in residential and light commercial finishing applications where a smooth substrate is needed between coats. Typical scenarios include sanding between coats of varnish, lacquer, or paint on wood trim, cabinetry, furniture, and doors. They are also suited for sanding bare or previously painted metal surfaces prior to applying a primer coat or finish coat. Painters, finishers, and general contractors reach for this grit range when surface prep quality directly affects the final appearance of the finish.

Key Features

• 400A grit rating for fine between-coat sanding without aggressive stock removal

Compatibility

Designed as a general-purpose finish-sanding sheet for use on wood, metal, and previously coated surfaces requiring fine abrasive preparation between finish coats.

Installation Notes

These sheets are installed by hand or with a standard sanding block — no power tool required, though they are compatible with wet-sanding by hand on flat or contoured surfaces. When sanding between finish coats, allow each coat to fully cure per the finish manufacturer's specification before sanding. Work in a well-ventilated area and wear appropriate respiratory protection when dry-sanding lacquers or solvent-based finishes. Dispose of used wet-sanding water and slurry in accordance with local environmental regulations.
