2. The flooring panel of claim 1 , wherein each of the top surface of the decorative veneer layer top surface, the opposed bottom surface of the core layer, the first pair of opposing side edges, and the second pair of opposing side edges comprise the moisture barrier composition at a quantity from about 0.1 g to about 5.0 g per 2.67 sq.ft of flooring panel.

3. The flooring panel of claim 1 , wherein opposing side edges of the first and second pairs of opposing side edges are not profiled to define any form of an interlocking or other connecting or fastening mechanism by which adjacent floor covering boards can be attached to one another.

4. The flooring panel of claim 1 , wherein opposing side edges of the first and second pairs of opposing side edges comprise connecting structures.

5. The flooring panel of claim 4 , wherein the first pair of opposing side edges define a complementary connecting structure.

6. The flooring panel of claim 4 , wherein a first side edge of the first pair of opposing side edges defines a tongue structure, and wherein a second side edge of the first pair of opposing side edges defines a groove structure.

7. The flooring panel of claim 4 , wherein the second pair of opposing side edges defines a complementary connecting structure.

8. The flooring panel of claim 7 , wherein a first side edge of the second pair of opposing side edges defines a tongue structure, and wherein a second side edge of the second pair of opposing side edges define a groove structure.

9. The flooring panel of claim 1 , wherein the core layer comprises a plurality of core layers.

10. The flooring panel of claim 1 , wherein the moisture barrier composition provides a water resistance or barrier treatment to the flooring panel.

11. A method of making the flooring panel of claim 1 , comprising:

forming the composite panel structure by applying the decorative veneer layer to the core layer such that the opposed bottom surface of the decorative veneer layer overlies the top surface of the core layer and such that the first pair of opposing side edges extends between the opposed bottom surface of the core layer and the top surface of the decorative veneer layer and a second pair of opposing side edges extends between the opposed bottom surface of the core layer and the top surface of the decorative veneer layer;

applying a 100% solid UV curable moisture barrier composition to the top surface of the decorative veneer layer and one or more of the opposed bottom surface of the core layer, the first pair of opposing side edges, and the second pair of opposing side edges at a quantity from about 0.1 g to about 5.0 g per 2.67 sq.ft of flooring panel; and

curing the applied 100% solid UV curable moisture barrier composition, thereby producing the 100% solid UV cured moisture barrier at a quantity from about 0.1 g to about 5.0 g per 2.67 sq.ft of flooring panel.

12. The method of claim 11 , wherein the moisture barrier composition is applied to the opposed bottom surface of the core layer after the decorative veneer layer has been adhered to the core layer.

13. The method of claim 11 , wherein the 100% solid UV curable moisture barrier composition is applied to the core layer bottom surface before the veneer layer has been adhered to the core layer.

14. The method of claim 11 , wherein the 100% solid UV curable moisture barrier composition is applied to the opposed bottom surface of the core layer after application of the decorative veneer layer to the core layer.

15. The method of claim 11 , wherein the 100% solid UV curable moisture barrier composition is a 100% solid UV curable hydrophobic sealer, and wherein the moisture barrier composition is roll coated on the opposed bottom surface of the core layer.

16. The method of claim 15 , wherein the core layer is a high density fiberboard (HDF), and wherein the 100% solid UV curable moisture barrier composition is roll coated onto the core layer while the HDF is in raw panel form.

17. The method of claim 11 , further comprising cutting the core layer to a desired floor panel size.

18. The method of claim 17 , further comprising hot-pressing a hardwood, softwood, or woody grass veneer face to an untreated opposing side of the core layer.

19. The method of claim 18 , wherein the hot-pressing does not decrease moisture resistance of the 100% solid UV curable moisture barrier composition.

20. The flooring panel of claim 1 , wherein the decorative veneer layer is a decorative wood veneer layer.

21. A method of making the flooring panel of claim 1 , comprising:

applying a 100% solid UV curable moisture barrier composition to the opposed bottom surface of the core layer;

curing the applied 100% solid UV curable moisture barrier composition, thereby producing the 100% solid UV cured moisture barrier;

after the step of producing the 100% solid UV cured moisture barrier forming the composite panel structure by hot-pressing the decorative veneer layer to the core layer such that the opposed bottom surface of the decorative veneer layer overlies the top surface of the core layer and such that the first pair of opposing side edges extends between the opposed bottom surface of the core layer and the top surface of the decorative veneer layer and a second pair of opposing side edges extends between the opposed bottom surface of the core layer and the top surface of the decorative veneer layer.

22. The method of claim 21 , wherein the hot-pressing does not decrease moisture resistance of the 100% solid UV curable moisture barrier composition on the opposed bottom surface of the core layer.

23. The method of claim 21 , wherein the decorative veneer layer is a decorative wood veneer layer.

24. The flooring panel of claim 1 , wherein the top surface of the decorative veneer layer and the opposed bottom surface of the core layer comprises the 100% solid UV cured moisture barrier composition, and wherein the first pair of opposing side edges and the second pair of opposing side edges comprises a moisture barrier composition that is not a 100% solid UV cured moisture barrier composition.
