Sanding sponges are sponge-like sanding tools used for sanding wood, drywall, and plastic. A sanding sponge is like sandpaper, but the abrasive material is attached directly to the flexible foam instead of a sheet of paper. Sand sponges, similarly, come in a variety of particle sizes; the smaller the particle size, the coarser the grit and the more material the sand sponge removes. While higher grit will give you a smoother finish but remove less material. It also comes in various sizes. Larger sponges can be used to smooth drywall or prepare furniture for paint, smaller sponges can handle detail work. Sanding sponge consists of three parts: Foam – usually made of EVA (Vinyl Acetate), Polyurethane or recycled polyurethane waste, Bond resin, and abrasive grain – made of Alumina or White Alumina to make. You can use them for wet or dry sanding. They are more durable than sandpaper and can be reused. A sanding sponge with channels built into the surface helps prevent the abrasive from becoming clogged with dust. They are effective on both flat and contoured surfaces, and the ductility of the sand sponge can be used for round grinding and curved surface sanding.

Learning how to use it correctly can make your tasks easier and more precise. First of all you need to find the right sand sponge type and particle size according to the task, different particle sizes are suitable for different work surfaces. Before sanding, also make sure you have the relevant equipment on, such as a mask, and if necessary, goggles and gloves. Sanding usually involves a coarse-grain sanding followed by a fine-grained finish, and if you want to reduce dust spread, you need to dampen the sanding sponge. The item is then scrubbed to remove surface texture and rough marks. If the sponge gets clogged during use, you just need to soak and rinse the sponge in water and you can use it again.

When sanding with BINIC sponge sand, it is not only the high removal rate. When preparing base surfaces for subsequent painting, extremely smooth results and excellent workpiece surfaces with low scratch depth are achieved. We will strictly control the products before they leave the factory, and meet the different needs of customers.
