a relief decorative layer attached to the front face of the backing layer and comprising: a layer of a base polymer attached to the front face of the backing layer and substantially covering the front face of the backing layer; and a relief element made of a layer of an overlay polymer attached to the layer of base polymer and covering a portion thereof. ## Claims ### Claim 1 A decorative panel comprising: a backing layer having a back face for abutting a panel-receiving surface and a front face opposite to the back face, the front face of the backing layer including a relief element; a relief decorative layer attached to the front face of the backing layer and comprising: a layer of base polymer attached to the front face of the backing layer and covering the front face of the backing layer entirely, the layer of base polymer having a substantially constant thickness across the front face of the backing layer; and a layer of overlay polymer attached to the layer of base polymer and covering a portion thereof, the layer of overlay polymer corresponding to the relief element, wherein the overlay polymer and the base polymer are polymerized together to define an integral structure. ### Claim 2 (depends on 1) The decorative panel as claimed in claim 1, wherein the overlay polymer and the base polymer have different colors. ### Claim 3 (depends on 1) The decorative panel as claimed in claim 1, wherein the overlay polymer and the base polymer are resin gelcoat polymers. ### Claim 4 (depends on 3) The decorative panel as claimed in claim 3, wherein the overlay polymer comprises styrene monomer and unsaturated polyester. ### Claim 5 (depends on 3) The decorative panel as claimed in claim 3, wherein the base polymer comprises unsaturated polyester. ### Claim 6 (depends on 1) The decorative panel as claimed in claim 1, wherein the overlay polymer and the base polymer are selected from the group consisting of: paint and urethane. ### Claim 7 (depends on 1) The decorative panel as claimed in claim 1, wherein the base polymer further comprises a catalyst compound. ### Claim 8 (depends on 7) The decorative panel as claimed in claim 7, wherein the catalyst compound comprises benzoyl peroxide. ### Claim 9 (depends on 1) The decorative panel as claimed in claim 1, wherein the relief element is indented towards the backing layer. ### Claim 10 (depends on 9) The decorative panel as claimed in claim 9, wherein the relief element is received in a recess defined in the front face of the backing layer configured to accommodate the relief element and a portion of the layer of the base polymer. ### Claim 11 (depends on 1) The decorative panel as claimed in claim 1, wherein the relief element projects away from the backing layer. ### Claim 12 (depends on 1) The decorative panel as claimed in claim 1, wherein the backing layer comprises a ridge defined in the front face, the ridge being configured to accommodate thereon the relief element and a portion of the layer of the base polymer sandwiched between the relief element and the backing layer. ### Claim 13 (depends on 1) The decorative panel as claimed in claim 1, wherein the relief element defines a grid pattern. ### Claim 14 (depends on 1) The decorative panel as claimed in claim 1, further comprising a barrier layer covering the relief decorative layer. ### Claim 15 (depends on 14) The decorative panel as claimed in claim 14, wherein the barrier layer is made of a transparent polymer. ### Claim 16 (depends on 1) The decorative panel as claimed in claim 1, wherein the decorative panel is one of a faux-tile panel and a faux-stone panel. ### Claim 17 (depends on 1) The decorative panel as claimed in claim 1, wherein the panel-receiving surface is one of a wall, a floor, and a ceiling. ### Claim 18 (depends on 17) The decorative panel as claimed in claim 17, wherein the panel-receiving surface is one of a wall of a bathroom and a floor of a bathroom. ### Claim 19 A decorative panel comprising: a backing layer having a back face for abutting a panel-receiving surface and a front face opposite to the back face, the front face of the backing layer including a relief element; a layer of base polymer having a front face and a back face attached to the front face of the backing layer, the layer of base polymer covering the front face of the backing layer entirely, the layer of base polymer having a substantially constant thickness across the front face of the backing layer; and a layer of overlay polymer having a front face and a back face attached to the front face of the layer of base polymer, the layer of overlay polymer covering a first portion of the layer of base polymer, the first portion of the layer of base polymer corresponding to the relief element, wherein the layer of overlay polymer and the layer of base polymer are polymerized together to define an integral structure in the first portion of the layer of base polymer, and wherein the layer of base polymer further includes a second portion which is uncovered by the layer of overlay polymer, the front face of the layer of overlay polymer and the second portion of the layer of base polymer together defining relief structures.
