How to Reseal Engineered Wood Floors

Engineered wood floors are made from multiple wood layers that are glued together. The top layer of hardwood veneer has a wear layer that can become dull and worn from day to day use. Restoring the luster to your floor involves a resealing or recoating process of gently sanding the surface and applying a polyurethane finish. If you recoat your floor as it begins to become dull, you can restore your floor to its original shine.

Instructions

    • 1

      Remove all furniture and rugs from the room.

    • 2

      Vacuum the floor to remove dust and debris.

    • 3

      Wipe the floor with hardwood floor cleaner. Wash baseboards at the same time. Use clean damp rags to wipe all residue from the floor. Wait until the surface is completely dry before continuing.

    • 4

      Place a buffing pad on the bottom of a circular buffing machine. Place a 150-grit abrasive screen over the pad.

    • 5

      Abrade the surface of the floor lightly with the buffing machine. Sand the corners and close to the baseboards with a hand sander fitted with a 120-grit screen.

    • 6

      Vacuum the entire surface to remove dust. Vacuum along baseboards as well.

    • 7

      Wipe the floor, baseboards and walls with a cloth dampened with pure mineral spirits to remove all traces of dust.

    • 8

      Tip the can of floor finish back and forth to avoid producing air bubbles while gently mixing the contents. Pour the finish into a clean paint tray.

    • 9

      Apply the floor finish around the edges of the room with a paint brush.

    • 10

      Dip a long-handled floor pad into the finish. Drain excess finish from the pad. Apply the finish to the floor beginning along the edges and working outward. Use long, smooth strokes in the direction of the wood grain, overlapping each stroke.
