  • Publication number: 20150082741
    Abstract: A method of making a floor panel includes the steps of: providing an adhesive on a release member; laminating or marrying the release member to a bottom layer such that the adhesive is between the release member and the bottom layer; removing a portion of the release member to expose an area of the adhesive; and adhering a top layer to the area such that the top layer is offset with respect to the bottom layer in a direction of length and width and a marginal end portion of a top surface of the bottom layer and a marginal end portion of the bottom surface of the top layer is exposed.
