Sanding sponge KWB 089030 Coarse grit 3 pcs 125mm x 100mm x 1cm

Sanding sponge KWB 089030, coarse grit, is a double-sided abrasive tool with silicon carbide grain bonded in phenolic resin on a highly flexible polyurethane foam body. Each sponge measures 125 x 100 x 10 mm and is suitable for both wet and dry sanding; sanding residue can be washed off to extend working life. The pack contains 3 sponges designed for sanding shaped and contoured surfaces where flexibility and durability are required.

Advantages

The silicon carbide abrasive provides efficient material removal on varied surfaces while the flexible polyurethane foam body adapts to curves and profiles. Coarse grit ensures fast stock removal; the phenolic resin bond and washable surface contribute to a longer service life. Dual-sided coating offers even wear and practical use on both faces.

How to use

Select the KWB sanding sponge and, if needed, wet it slightly for wet sanding or use it dry for faster material removal. Apply even pressure and move along the contour of the workpiece to follow shapes and profiles. Rinse the sponge under running water to remove sanding waste when necessary and allow it to dry before storing. Replace the sponge when the abrasive surface becomes worn and no longer removes material effectively.

Recommendations

For best results on curved or irregular surfaces, start with the coarse KWB 089030 to remove bulk material, then progress to finer grits if a smoother finish is required. When wet sanding, use moderate pressure and periodically rinse the sponge to maintain abrasive efficiency.
