The flowthrough action rinses out dirt and finish to reduce loading so the pad can perform longer. The result is a stripping pad that removes old finish, dirt and build-up more effectively and more efficiently than stripping pads made the conventional way. The open web allows it to be washed easily and dried quickly. The benefit is a better-looking floor after recoating because of more thorough, uniform stripping. Black color. Sold 5 per package.
