A mezzanine floor includes a corrugated metal base with tongue and groove panels secured thereto, wherein the panels have been finished with a number of steps to achieve a combination of desired features, including durability, cleanability, water resistance and non-skid characteristics. The finishing steps include coating and curing a polyester acrylic layer, followed by coating and semi-curing at least one more layer of acrylic with no polyester. Then, a final layer of acrylic is coated and all of the layers are cured via electron beam and then ultraviolet radiation. The viscosity of the acrylic is varied during the successive coatings, and this produces the textured finish necessary for non-skid characteristics. The tongue and groove configuration is offset to enhance stability at the joints between adjacent panels. The combination of the textured and durable surface finish, the internal cohesiveness of the panels and the tongue and groove also enables the panels to be installed at reduced cost, either via screws with reduced size heads or by gluing.

This disclosure relates to the use of electron beam curing and bonding irradiation in an in-line process of laminating a decorative layer, such as printed paper, to an adhesive-coated particle board panel or the like, wherein an electron-curable top coating is adsorbed into the paper and, under the electron-beam irradiation, cures with the adhesive to produce a monolithically bonded paper-to-panel polymeric structure with a hard scratch and abrasion-proof surface imparted to the paper.
