General purpose sandpaper sheets optimized for use on all surfaces have an open-coat aluminum oxide abrasive applied to a paper backing. Aluminum oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds. Open-coat abrasives have grit on about 50% of the surface leaving space between the abrasive grains to prevent swarf from clogging the surface which keeps the workpiece cooler. The paper backing provides a smooth, flat surface to provide consistent pressure across the work surface. Compatible surfaces and substrates include paint, plastic, composites, gelcoat, fiberglass, and carbon steel.

Wet/dry sandpaper sheets optimized for use on all surfaces have an aluminum oxide abrasive applied to a paper backing. Paper-backed wet/dry abrasives are flexible and can be used dry or with water or another lubricant to prevent loading and minimize dust. Aluminum oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds. Compatible surfaces and substrates include paint, plastic, composites, gelcoat, fiberglass, and carbon steel.

Hand-sanding sheets for use on soft woods have an open-coat garnet abrasive applied to a paper backing. Garnet is a natural, sharp abrasive that won't leave scratch marks on bare and soft wood, such as pine and fir. Garnet is not as durable as synthetic abrasives. Open-coat abrasives have grit on about 50% of the surface leaving space between the abrasive grains to prevent swarf from clogging the surface which keeps the workpiece cooler. The paper backing provides a smooth, flat surface to provide consistent pressure across the work surface. Examples of soft wood include pine, fir, cedar, and spruce.
