Screening and Recoating is a light refinishing process that involves buffing (or “screening”) the top layer of the floor’s existing finish and applying a fresh coat of polyurethane. This method is ideal for floors with minor scratches, dullness, or light wear. Since it doesn’t remove the wood itself, it is less invasive, quicker, and more cost-effective than full sanding. However, screening is ineffective for deep scratches, discoloration, or severe damage.

Full Sanding, on the other hand, involves sanding down the entire floor to bare wood, removing all old finishes, deep scratches, and stains. This process allows for stain changes and provides a completely fresh surface. Full sanding is recommended when floors have significant damage, deep scratches, or unevenness. It is more time-consuming, expensive, and requires professional expertise, but it results in a completely renewed hardwood floor.

In summary, screening and recoating is a maintenance method for floors in good condition, while full sanding is a complete restoration process for heavily worn or damaged floors. Choosing the right method depends on the floor’s condition and desired results.
