Abstract
Abstract A natural stone panel is constructed from rectangular sheets, slabs or blocks of natural stone, particularly marble or onyx and constructed by placing an array of rectangular stone blocks on a work surface, placing a fiberglass backing on the upper surface of the array, applying an adhesive, which can have a stone dust filler, to the joints between adjacent blocks, on the blocks and on the fiberglass backing, which is rolled into contact with the blocks. After hardening or curing of the adhesive, the exposed stone block surfaces can be polished, an overlay of clear plastic applied to the surface of the stone blocks, and the panel edges trimmed with a suitable cutting tool. The panels formed can be wall mounted by a suitable adhesive bonding the fiberglass backing to the wall surface, or alternatively, the panels can be adhesive bonded to a floor surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A method for making a decorative natural stone panel from blocks of natural stone, fiberglass backing, and an adhesive including dust formed from the same stone material as forms said blocks, a curing agent, and a resin, the method comprising the steps of arranging on a horizontal work surface an array of said blocks of natural stone, placing a roll of said fiberglass backing along one edge of said array, forming said adhesive by combining said dust, said curing agent and said resin, unrolling said roll and simultaneously applying said adhesive to the space between said blocks to the upper surface of said roll, smoothing said fiberglass backing upon said blocks, curing the adhesive to form a hardened resin and a rigid unit having end edges, lifting the rigid unit from said work surface, and subsequently polishing the exposed surface of said blocks to a high gloss, and applying to said polished blocks a protective coating.
Claim 2
Independent Claim
156 words
A method for making a decorative natural stone panel from blocks of natural stone, fiberglass backing, and an adhesive including dust formed from the same stone material as forms said blocks, a curing agent, and a resin, the method comprising the steps of arranging on a horizontal work surface an array of said blocks of natural stone, placing a roll of said fiberglass backing along one edge of said array, forming said adhesive by combining said dust, said curing agent and said resin, unrolling said roll and simultaneously applying said adhesive to the space between said blocks to the upper surface of said roll, smoothing said fiberglass backing upon said blocks, curing the adhesive to form a hardened resin and a rigid unit having end edges, lifting the rigid unit from said work surface, and subsequently polishing the exposed surface of said blocks to a high gloss, and applying to said polished blocks a protective coating.
Claim 3
Dependent Claim
21 words
The method of claim 1 wherein said blocks of natural stone are blocks of marble, and said dust is marble dust.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein said blocks of natural stone are blocks of onyx and said dust is onyx dust.
Claim 5
Dependent Claim
78 words
The method of claim 1 wherein the method includes after the lifting step and before the polishing step the step of cutting said end edges to form a standard sized module, and wherein said adhesive is formed by combining said dust with a methyl ethyl ketone curing agent and a resin selected from the group consisting of epoxy and polyester resins, whereby said panel is fire-resistant and stable with respect to discoloration or ignition below about 550° F.
Claim 6
Dependent Claim
12 words
The method of claim 4 wherein said resin is a polyester resin.
Claim 7
Dependent Claim
21 words
The method of claim 1 wherein said protective coating is formed by applying a clear polyester resin to the polished blocks.
Claim 8
Dependent Claim
26 words
The method of claim 6 together with the additional step of cutting said polished blocks into panels having dimensions of about 30 inches by 54 inches.
