High-Performance 7940 Siaair 5″ Foam Sanding Discs – 1000 Grit

The 7940 Siaair 5″ Sanding Disc (1000 Grit) is the essential abrasive for the intermediate stages of surface finishing. Designed to bridge the gap between heavy sanding and final polishing, this disc features an innovative foam backing that provides a cushioned touch. This allows the abrasive to conform perfectly to body lines, contours, and complex shapes without the risk of cutting through edges or creating uneven pressure marks. It is the ideal choice for professionals in automotive refinishing and woodworking who need a consistent, uniform base.

Engineered for maximum versatility, the 7940 Siaair excels in both wet and dry sanding environments. It utilizes high-quality aluminum oxide grit bonded with resin over resin, supported by a special coating process that drastically reduces clogging. This anti-loading technology keeps the disc cutting effectively for longer periods, minimizing downtime associated with disc changes. Whether you are smoothing primer fillers or matting old varnish, the durability of the Siaair system ensures cost-effective operation for shops of any size.

This 1000 grit variant is specifically optimized for conditioning surfaces prior to the application of finer grits or topcoats. It provides an even scratch pattern that is perfect for matting conventional lacquers, blending repairs, and preparing gelcoat polyester, plastics, and acrylic glass. With 10 discs per box, you have a reliable supply of premium abrasives designed to deliver a flawless, professional-grade surface foundation every time.
