Norton 662611-39364 Tufbak Durite 320A Grit Abrasive Sheet

Product Description

The NORTON 662611-39364 is a full-sheet waterproof abrasive sanding sheet built on the Tufbak Durite T414 platform. It uses a close-coat construction on a durable waterproof paper backing, making it suited for wet or dry sanding applications where consistent finish quality matters. At 320A grit, this sheet falls in the fine-abrasive range, typically used for finish sanding, surface preparation before coating, and between-coat leveling. Each sheet measures 9 inches by 11 inches, a standard hand-sheet size compatible with most manual and block-sanding workflows. Trade finishers, body technicians, and surface prep crews reach for this product when a controlled, fine cut is needed on wood, metal, or primed surfaces.

This sheet is designed for close-coat wet-or-dry sanding tasks in both shop and field environments. The waterproof paper backing allows use with water or light cutting fluids, helping to flush swarf and extend sheet life during wet sanding passes. At 320A grit, it is appropriate for final prep before topcoat application, removing light scratches, or smoothing primer on metal and wood substrates. It is packaged and sold per sheet, with a minimum order quantity of 250 sheets, making it well suited for production shops and high-volume finishing operations that cycle through abrasive media regularly.

Installation Notes

Abrasive sheets should be installed on a flat or contoured sanding block appropriate to the substrate being worked. When wet sanding, use clean water or the appropriate cutting fluid and rinse the sheet regularly to maintain cut rate. Inspect the sheet for loading or tears before each use and replace when abrasive performance degrades. No power tools or specialized trade licensing are required, but proper respiratory protection is recommended when dry sanding.
