What Is Liquid Sandpaper?
Liquid sandpaper is a chemical solution that removes the thin top layers of the surface of a glossy painted item. It roughens the glossy surface, making it easier to be repainted without having to be sanded down. Otherwise, the next coat of paint will not stick tightly to the surface and may need to be repainted. Liquid sandpaper can be found in hardware, home improvement or paint stores.
