Doublesided wearresistant sponge sanding blocks These sanding sponges use durable, wearresistant sponge material and feature doublesided surfaces for extended use. They resist tearing and maintain effectiveness over repeated use, helping you finish tasks with fewer replacements. Six grits for multiple applications The set includes six sponges with grits of 120, 150, 180, 240, 400, and 600. Each grit is designed for specific sanding tasks, allowing you to achieve the desired results on wood, paint, metal, plastic, or drywall surfaces. Use coarser grits for material removal and surfaces prep, and finer grits for finishing and smoothing. Washable and reusable These sanding blocks are washable and reusable, offering a costeffective solution. They can be used wet or dry, and can even be used directly in water. Their water storage function helps minimize flushing and improves work efficiency. Portable and easy to handle The sanding sponges are compact and lightweight, suitable for both flat and irregular surfaces. Their portable size makes them easy to carry between job sites, improving convenience and workflow. Recommended use scenarios Woodworking: remove rough spots, feather edge joints, and prep for finishing with the appropriate grit progression. Paint and metal: smooth painted or metal surfaces before repainting or coating, using finer grits for final finishing. Drywall and plastic: blend patches, sealants, or edges for a seamless finish on drywall or plastic components. Compatibility and performance Suitable for wood, paint, metal, plastic, and drywall surfaces. Doublesided design extends lifespan and reduces replacement frequency. Works with wet or dry sanding, with a builtin water storage feature to support efficient cleaning and cutting action.
