Norton 66261139354 Sanding Sheet 400 Grit Silicon Carbide

Product Description

The NORTON 66261139354 is a 400-grit silicon carbide sanding sheet designed for super fine finishing work on a wide range of surfaces. Part of the T414 series, this sheet uses an open-coat design on a B-weight paper backing, allowing it to perform in both wet and dry sanding applications. The silicon carbide abrasive delivers sharp, consistent cutting action suited to final-pass smoothing, paint prep, and finish sanding on wood, metal, plastics, and composites. It is sold individually and commonly used by finishing carpenters, auto body technicians, painters, and metal fabricators who need controlled material removal at fine grits.

This sanding sheet is appropriate for residential and light commercial finishing tasks where a super fine surface profile is required. Its wet and dry compatibility makes it a practical choice for between-coat sanding on lacquer, varnish, or primer, as well as dry finishing on bare materials. The open-coat construction helps resist loading on softer or resinous materials. It is suited to hand sanding blocks and compatible hand-sanding tools that accept standard sheet stock.

Key Features

Installation Notes

No power tools or trade licensing are required for hand sanding applications. Ensure the backing surface or sanding block is clean and flat before loading the sheet to avoid uneven abrasion. When wet sanding, allow adequate drying time before applying coatings. Dispose of used sheets in accordance with local regulations if sanding lead-based paint or hazardous coatings.
