- the decorative layer 18 may be manufactured from paper that is impregnated with a thermosetting resin and provided with the desired aesthetic color and/or pattern. Other materials may make up the decorative layer 18, such as real wood veneer, pulverized stone, or other materials. Additionally, it is possible to achieve a similar decorative appearance by applying a direct or indirect printing process onto the top surface of the core layer 17.
- the decorative layer 18 comprises the ink, dye, pigment or other marking substances applied to the core layer 17.
- the decorative appearance may be provided by etching, burning or otherwise marring the top surface of the core layer 17. Any such treatment that supplies such a decorative appearance on the top surface of the core layer 17 is contemplated to comprise the decorative layer 18 as defined herein.

- One illustrative example of such a means for adjoining adjacent panels is set forth in U.S. Patent No. 6,006,486 to Moriau et al. (which is incorporated herein in its entirety by this reference).
- the first edge 13 of the panel 10 includes the first coupling member 20.
- the first coupling member 20 includes a protrusion 21 with a rib 30 formed on the underside thereof.
- the second coupling member 22 includes an upper lip 33, a lower lip 31, and a detent 32 formed within the lower lip 31.

- the tip of the protrusion 21 of panel 10a is inserted into the recess 23 of panel 10b at an angle above the horizontal, and the panel 10a is then rotated clockwise until the panels 10a and 10b are within substantially the same horizontal plane, as illustrated.
- contact is made between the complementary coupling members 20, 22 of the two panels 10a, 10b in four contact zones as shown in Fig. 3.
- the protrusion 21 of panel 10a contacts the upper lip 33 and the lower lip 31 of panel 10b at contact zones 40 and 41, respectively.
- Contact zones 40 and 41 help locate the panels into substantially the same horizontal plane.

- selectively applied it is meant that the barrier composition 60 is applied only to the intended area of application, and that the barrier composition 60 is not applied to neighboring areas or any other areas besides the selected and intended area of application.
- the barrier composition 60 fonns a moisture barrier between the first and the second abutment surfaces 50, 52, such that water and other liquids along the first surface 11 of the adjacent panels 10a, 10b are substantially prevented from seeping past that moisture barrier.
- the barrier composition 60 may be selectively applied only to substantially all of the second abutment surface 52 at a location corresponding to contact zone 43.

- a vacuum is applied at an opposite side of the edge of the panel to remove excess barrier composition from the floor covering panel.
- Excess barrier composition is returned to a vessel for re-use.
- Use of such a vacuum coating method allows for precise application of the barrier composition to a floor covering panel by way of adjusting the pressure/vacuum ratios.
- a further method that may be utilized to apply the barrier composition to the floor covering panel is the use of a roll coat applicator.
- the barrier composition may be applied to the floor covering panels by a transfer roller that is supplied with the barrier composition from a supply reservoir.
- the application of the barrier composition can be precisely controlled by adjusting the parameters used in the application.
- a further method of applying the barrier composition to the floor covering ⁇ panels is achieved by use of a multi-spray head applicator. This method will allow application of the amount of barrier composition to the flooring profile with precision and accuracy.
- multiple spray applicators may be fitted with nozzles and situated to spray the barrier composition on selected portions of the side edges of a floor covering panel.
- the spray applicators may pulse at a high frequency to apply the barrier composition to the desired position on the floor covering panel, which pulsing action may also assist in keeping the spray head clean.
