At Aozhong, we manufacture double-sided sponge sanding blocks specifically designed for uniform manual sanding, edge finishing, contour polishing, and surface finishing across multiple industries. These sanding sponges are made with a flexible foam backing and a durable abrasive coating, providing consistent cutting performance while maintaining excellent adaptability to curved and irregular surfaces.
This sponge sanding kit is widely used in automotive painting, woodworking, furniture manufacturing, metalworking, plastic component finishing, composite material processing, and DIY repairs. The combination of different grits allows operators to complete the entire sanding process—from material leveling to ultra-fine finishing—more efficiently, while reducing the frequency of grit changes.
Unlike traditional sanding sheets, which are prone to wrinkling or difficult to control on curved surfaces, our sponge sanding blocks distribute pressure more evenly, reducing deep scratches during manual sanding. The soft sponge core also enhances operator comfort during extended use.
The color-coded grit system helps workshops and distributors quickly identify application scenarios and plan sanding sequences more efficiently.
In many workshops, abrasive materials wear out quickly due to edge wear, poor abrasive bonding, and lack of flexibility. Aozhong Sponge Sanding Blocks are designed to address these issues with the following features:
The sanding surface remains consistent through repeated use, helping to reduce premature sandpaper shedding during automotive primer sanding, wood finishing, and plastic surface refinement.
Grit Range Grade Typical Applications
120–180 Medium Surface leveling, deburring, rough grinding
240–320 Fine Intermediate sanding, refining scratches
500–600 Superfine Primer sanding, surface smoothing
800–1000 Superfine Paint transition sanding, preparation for polishing
1200–1500 Micro-fine Ultra-fine finishing, fine surface correction
