Finishing Processes

As a part of the restoration process, our artisans explore the intricate details of preserving the historical integrity of lighting fixtures including color matching and sheen of the original finish.

Custom lighting finishes are available in custom painted colors, sheen, and textures as well as custom patina colors on bronze, copper, and brass components.

Each surface is cleaned and inspected to determine the optimal surface profile to achieve the desired finish. To alter the surface of an existing luminaire, our processes involve a wide range of capabilities including metal polishing as well as media blasting to remove old finishes and foreign material in preparation for a refinish.

Our artisans can match any color or finish utilizing a variety of processes involving powder coat, spray, hot or cold patina custom recipes and color blending an existing finish.

Grand Light exercises meticulous techniques that are unparalleled in the application of protective coatings including UV resistant protective lacquer with various customized sheens and tints. Finishes requiring a protective wax are hand buffed with multiple coats of museum grade clear and tinted waxes.

Our finishing processes include:

Each surface is meticulously cleaned by our artisans prior to all finish applications. Grand Light utilizes a wide range of proprietary cleaning solutions and methods including ultrasonic dipping, stripping, soda blasting, and hand cleaning to remove the accumulation of foreign material such as oil, dust, grime, and staining.

Grand Light’s industrial ultrasonic console system provides the most advanced and portable cleaning tank available. These powerful units incorporate stainless steel tanks combined with superior Vibra-bar® technology transducers and patented high performance generators providing versatile performance from the simultaneous presence of many ultrasonic frequencies within the cleaning chamber.

Each surface is inspected to determine the optimal surface profile to achieve the desired finish. To alter the surface of an existing luminaire, our specialists utilize different types of blasting media, including plastic bead blasting, walnut blasting, glass blasting, garnet and soda blasting.

These processes can be used to smooth a rough surface, roughen a smooth surface, shape a surface, or remove old finishes and surface contaminants in preparation for refinish application. Grand Light’s H2O soda blasting equipment’s sensitivity will actually remove the ink from a business card without damage to the underlying paper.

Our artisans can match any color or finish utilizing a variety of processes including artist brush, powder coat, spray, and color blending an existing finish. From replicating an existing finish to hand painting intricate patterns, our artisans have decades of experience providing high quality paint applications to historic and custom lighting fixtures.

Our restoration artisans have decades of experience polishing and buffing a wide range of metal surfaces including aluminum, brass, copper, silver, and gold. Grand Light utilizes various rouges that graduate from coarse to fine. Our artisans produce surfaces with specular reflection or a satin finish while smoothing surfaces of scratches and imperfections.

Our artisans utilize a variety of hot or cold patina custom recipes to create or replicate any color or finish desired. Grand Light artisans creatively burnish patina on surface edges and details to greatly enhance the finish aesthetics.

The application of hot or cold patinas are performed in the company’s 20x15ft spray booth with an AbsolutAire Direct-Fired Make Up Air heating and ventilation equipment. All hot patina components are preheated in our two CCI Thermal Tech programmable infrared ovens.

Grand Light exercises meticulous techniques that are unparalleled in the application of protective coatings including UV resistant protective lacquer with various customized sheen and tints. A minimum of two coats of solvent based clear lacquer containing tarnish inhibitors are applied to fixtures. Finishes requiring a protective wax are hand buffed with multiple coats of museum grade clear and tinted waxes.
