Our foam sanding blocks are both washable and reusable, making them versatile tools for polishing, whether wet or dry. Designed to suit various needs, the blocks come in shapes ideal for different tasks—flat blocks for larger surfaces and contoured ones for more intricate work. Made from high-density sponge, these blocks are soft and flexible, providing cushioning that enhances control and minimizes the risk of scratching the surface. The sandpaper blocks are available in different grit sizes, with lower numbers indicating a coarser surface for heavy material removal and higher numbers offering a finer surface for smoothing and finishing.
