SIA 7983 siasponge flex Foam Sanding Disc 150 mm, 15 Holes, Ultrafine, 1 pc

SIA 7983 siasponge flex Ultrafine is a soft foam sanding disc designed for curved and contoured surfaces. Its elastic backing helps maintain even contact with the workpiece for a consistent sanding finish.

This 150 mm, 15-hole version is designed for dry sanding. The blue colour identifies the Ultrafine grade, with a manufacturer-stated sanding range of 800–1000. This range is a guide to sanding performance, rather than a single P-grade designation.

Key features:

• Soft 13 mm foam backing follows surface contours.
• Ultrafine grade for fine sanding and matting.
• 150 mm diameter with 15 holes for compatible dust extraction systems.
• Low clogging thanks to the abrasive foam structure.
• Suitable for manual and random orbital sanding.
• Sold as 1 pc; the price is for one disc.

Applications

Matting painted and lacquered surfaces, intermediate sanding of coatings and fine sanding of primer filler. Select the abrasive grade according to the coating system’s requirements.
