3M Softback Sanding Sponges 140mm x 115mm

Flexible Foam Sanding Sponges for Hand Sanding and Surface Preparation

3M Softback Sanding Sponges 140mm x 115mm are flexible foam-backed abrasives designed for effective hand sanding, surface preparation and finishing across automotive, industrial and trade applications.
These sanding sponges feature a soft foam backing that allows them to conform easily to contours, curves and irregular surfaces, providing consistent contact and even abrasion. The durable abrasive coating delivers reliable cutting performance while maintaining control and comfort during extended use.

The sanding sponges function as versatile hand sanding tools suitable for dry or damp sanding tasks. Their flexible construction helps reduce finger fatigue and improves finish quality on shaped surfaces, edges and profiles that are difficult to sand with rigid abrasives.

Key benefits include excellent flexibility, improved surface contact and ease of handling. The sponge format allows controlled sanding without gouging, making them ideal for both material removal and finishing work.

Compared to traditional sandpaper sheets, 3M Softback Sanding Sponges offer improved durability, better conformability and longer service life. They are well suited to automotive refinishing, woodworking, metal preparation and general workshop sanding where precision and control are required.
