Abstract

The present invention is filler composition and a method for applying the filler composition to an engineered hardwood flooring board in order to fill the defects in the veneer layer of the board to provide the desired appearance to the exterior of the board. The filler composition is applied continuously to a veneer layer forming the exterior surface of an engineered hardwood flooring board in a manner such that all defects and cracks in the veneer layer are filled with the filler composition. After application, the excess filler composition is removed from the board such that only the filler composition filling the defects in the veneer layer remains on the board.

Claims

1. A method for repairing defects in a surface of a flooring board, the method comprising the steps of:

a) providing an amount of a filler composition;

b) applying an excess amount of the composition to the surface of the board including the defects to fill the defects with the composition; and

c) removing the excess composition from the surface.

2. The method of claim 1 further comprising the step of curing the filler composition after removing the excess composition from the surface.

3. The method of claim 1 further comprising the step of curing the filler composition prior to removing the excess composition from the surface.

4. The method of claim 1 wherein the step of removing the excess composition from the surface comprises sanding the excess composition off of the surface.

5. The method of claim 1 wherein the step of removing the excess composition from the surface comprises scraping the excess composition off of the surface.

6. The method of claim 1 wherein the filler composition is UV-curable.

7. The method of claim 1 wherein the step of applying the composition comprises applying the composition along a grain direction of the board.

8. The method of claim 1 wherein the step of applying the composition comprises applying the composition at an angle with respect to a grain direction of the board.

9. A flooring board having a veneer layer formed by the process of:

a) providing an amount of a filler composition;

b) applying an excess amount of the composition to the veneer layer of the board including defects to fill the defects with the composition; and

c) removing the excess composition from the veneer layer.

10. The board of claim 9 wherein the filler composition includes a light-curable resin filler, a filling agent, a photo-initiator, and optionally a thickener.

11. The board of claim 10 wherein the filler is selected from the group consisting of:

polyurethane acrylate, epoxy acrylate, polyester acrylate, polyether acrylates, polymers including acrylic monomers, and polyisocyanates.

12. The board of claim 10 wherein the filling agent is selected from the group consisting of:

inorganic oxides and fumed silica.

13. A filler composition for use in filling and repairing defects and cracks in a veneer layer of an engineered flooring board, the composition comprising:

a) a resin filler;

b) a filling agent;

c) a photo-initiator;

d) optionally a thickener; and

e) optionally a pigment.

14. The filler composition of claim 13 wherein the resin filler is light-curable.

15. The filler composition of claim 14 wherein the resin filler is selected from the group consisting of:

polyurethane acrylate, epoxy acrylate, polyester acrylate, polyether acrylates, polymers including acrylic monomers, and polyisocyanates.

16. The filler composition of claim 14 wherein the filling agent is selected from the group consisting of:

inorganic oxides and fumed silica.
