Description

Sia 5163.3687.0240 Siaair 7940 6 Inch Disc, 240 Grit

The Sia 5163.3687.0240 is a 6 inch (150 mm) Siaair 7940 foam sanding disc in 240 grit, sold 10 discs per box. 240 grit is the coarsest grit in the Siaair 7940 range. The disc combines aluminium oxide abrasive with a knitted fabric and a pressure-equalising foam backing, so it follows contours, curves and profiles and leaves a low scratch depth.

Where 240 Grit Fits

Use 240 for matting and fine sanding of primer filler, especially on curves and in hard-to-reach areas where a hard pad would cut through edges. Follow it with 360 or 500 before paint. The Siaair range runs from 240 to 4000, so one system covers the whole job from primer to polish.

Who Uses It

Automotive refinishers, aerospace and composite shops, boat builders working with gelcoat and solid surface fabricators use the Sia 5163.3687.0240 for fine sanding of primer filler and matting. Sia lists it for lacquers, paints, plastics, acrylic glass, gelcoat and composites. It is not suited to glass, ceramic lacquers or stone.

Tips for Best Results

Keep the disc and the surface damp, as Sia recommends, and rinse the disc when slurry builds up. Use light, even pressure and keep the sander flat so the foam can spread the load. Wash the disc out after the job and let it dry flat; Siaair discs are washable and can be used many times.
