A process and tool for the application of wax onto watersport boards including, but not limited to, surfboards, longboards, foam top boards, skim boards, standup paddle boards, boogie boards, wake skateboards, and wake surfboards. The process includes shredding wax with the use of a handheld grating device having a cutting blade with grating holes. The process further includes distributing the grated wax fragments onto the surface of the watersport board while continuing to rub the wax over the cutting blade of the grating device and layering the grated wax fragments over areas of the board surface where grip is needed, and then gently pressing the wax fragments onto the surface of the board to create a texture for ideal grip and traction needed to stand on and control the watersport board. One or more scraper edges on the grating device allow for removal of the wax from the board surface.
