A screen and recoat is when you give your hardwood floors an extra sheen. Screening means to buff your floors before applying your coating, which will protect the surface of your floors. Screening is done with an industrial floor buffer to smooth out the surface of the wood with an abrasive pad. Buffing allows the coat to adhere to the wooden surface more effectively. The screen and recoat process restores the glow of the wood for a new and improved look.
