Sanding sponge blockconsists of three components: foam, usually made from EVA (ethylene vinyl acetate), PU (polyurethane) or recycled PU waste, a binder resin and sanding sponge gritmade of aluminum oxide, white aluminum oxide, silicon carbide, semi-friable aluminum oxide and so on.

The Advantages of foam abrasives

When sanding with foam abrasives, the focus is not only on removing as much material as possible. It is vital to achieving an absolutely smooth and even result when preparing surfaces for subsequent painting or varnishing. If the goal is to achieve a perfect workpiece surface finish with low scratch depth, applying pressure in two dimensions when sanding (such as using conventional sandpaper sponge) is not enough, for example when using paper-backed abrasives. Instead, pressure needs to be applied in three dimensions. Force can be applied in three dimensions by using the foam as the carrier material in connection with a flexible binder resin. This allows the grit to dissipate the contact pressure average. Advantage: the abrasive grit does not cut into the material as deeply and breaks off less. As such, less material is removed and no sanding through of the material occurs at the edges. Instead, we achieve a homogeneous surface.

Drywall Sponge vs Sanding

Sandpaper is a normal type of coated abrasive with various grits. Similarly, sanding sponge varies from a fine to extremely rough grit. However, sanding sponge has foam abrasives, which can be used to sand flat and contour surfaces while being wet or dry. Besides, after cleaning sanding sponge, it can be used again.

Sanding Sponge Application

We have sanding sponge for wood. Due to their conformability, foam abrasives are the ideal choice for areas that are difficult to access and have profiled surfaces. Hard-to-reach areas, such as door handle depressions, bumpers, and radiator grilles, are ideal fields of application for the foam abrasives. Unlike conventional sandpaper, sanding sponge can be folded without creating permanent creases, which allows a consistent sanding pattern due to improved grain consistency without swirl marks.

Oursanding sponge for trimworks very well. A combination of soft carrier material and flexible grit bonding reduces the clogging of the foam abrasives. When using a sanding sponge, sanding dust can be continuously removed from the spaces between the granules. Using more flexible binder resin and optimized distribution with improved abrasive grit, it has been possible to further improve the clogging characteristics. The sponge sanding pads or sponge sanding block can, therefore, be used multiple times.

The foam allows the abrasive sponge to shape itself to the product. With no folds or buckling, the sponge block sanding padprovides an even pattern free of scratching. A flexible abrasive surface of the sandpaper sponge lasts much longer than conventional surfaces, on which the abrasive grains crack apart and break off. With its soft backing material, the foam abrasive does not create pressure spots from fingers. It distributes the force of the sanding across the abrasive surface evenly.

Wet and Dry Sanding Sponge

Wet and dry sanding sponge is designed to help users for sanding wood, paint, metal, plastic, and drywall. Having a soft and flexible backing makes the foam abrasive continually release abrasive dust. Heat does not build up on the adhesive coating of the foam abrasive as you work. With less heat, there is less load up, and the product lifetime increases. Not only does sanding sponge block work wet or dry, but you can also even wash and reuse it. For example, if you need to clean the drywall dust, a wet sanding sponge can help you do the job. Sanding drywall mud with a spongeis an easy way to clean the dust and make the drywall smooth.
