SANDING Wood floor sanding involves three stages: coarse sanding with aggressive grit discs (24-60) to remove old finishes and level the floor; intermediate sanding with medium grit discs (80-120) to refine and correct imperfections; and fine sanding with fine grit discs (150-220) for a smooth, scratch-free surface, prepping the floor for further treatments or finishing.

Made of aluminum oxide abrasive, the semi-open/open structure reduces clogging and improves disc life. SCREENING The “screen and recoat” or “buff and coat” method is a less invasive alternative to full sanding, used to refresh a wood floor’s topcoat. Using mesh-like screen discs, this process roughens the existing finish, ensuring a new coating adheres well. Ideal for regular maintenance and minor touch-ups, it blends the floor’s field and perimeter for even stain and finish penetration, removing visible lines between areas. The result is a uniform floor appearance. Screening, often paired with a topcoat application, revives the floor’s look and tackles minor flaws without a complete refinish.
