3″ x 4″ SurfPrep film sheets for leveling and finish sanding
Film-backed abrasives are the sheets you reach for when you want a clean, even result, leveling a surface or putting on the finish pass. The film backing holds the grit flat for a consistent finish, cuts faster, and the tear-resistant edges hold up longer than paper.
The grit is aluminum oxide, and a sacrificial stearate coating keeps loading to a minimum, so the sheet stays cutting instead of clogging. They run on a hook and loop backing that grips the pad and pulls off clean.
