Preengineered hardwood is a type of flooring composed of many layers of wood that form a plank. The plank has two parts: the top layer, called a lamella, and the bottom part, called core. Unlike laminate flooring, preengineered hardwood is high quality material, since all its part are real wood. Because of its characteristics, appearance, and durability, preengineered wood is one of the most popular choices of flooring in the world. If your preengineered hardwood floor has scratches, it is possible to neutralise them without replacing the entire plank.

  1. 1

    Clean the whole scratched area with a soft brush, so you don't damage the floor finish any further. Be sure to pick up any debris or dirt, and thoroughly clean the surface. If the scratch is big and is already starting to resemble a crack, continue with the next two steps. If it's a surface scratch, skip to Step 4.

  2. 2

    Fill the scratch/crack with wood glue with a thick cosmetic sponge used for applying make-up. You could also use a small paintbrush or a piece of cloth.

  3. 3

    Use a slightly damp cloth to remove any excess glue around the scratch, and clean the area so there is no glue residue. Leave the wood glue to dry following the instructions on the package.

  4. 4

    Apply wood putty with a putty knife or a small trowel to fill in the scratch. Be sure to choose putty that is colour matched to your floor.

  5. 5

    Remove the excess wood putty around the scratch with a damp sponge.

  6. 6

    Leave the putty-filled scratches on your floor to dry thoroughly. Follow the manufacturer's instructions on the package carefully, because the putty needs to be completely dry and hardened before the next step.

  7. 7

    Sand the scratched area with fine sandpaper, making sure to follow the direction of the wood grain.

  8. 8

    Apply polyurethane, wood finish, or gloss to the area you treated with sandpaper. Use a fine art paintbrush and be very precise. Allow the finish to dry completely, and don't open the windows so no dust can come in and stick to the surface.

  9. 9

    Buff and shine the surface of your preengineered hardwood floor.

Tips and warnings
