The Story
The SiaSponge Block Soft Ultra-Fine Blue 10PK is engineered for precision finishing and ultra-smooth surface preparation. Designed with long-lasting sia Abrasives foam and aluminum oxide abrasive on all four sides, these sanding blocks provide exceptional control and a refined, consistent scratch pattern.
The blue color coding clearly identifies the ultra-fine grit (400 grit), making it easy to select the correct block for final sanding stages. Its soft, flexible foam core adapts effortlessly to edges, contours, and detailed profiles while maintaining even pressure across the surface. Ideal for final prep before painting, staining, or clear coating.
