Birchwood Technologies Metal Finishing Gels Work For In-Place Finishing Metal Surfaces Of Building Railings, Facade, Sculpture, And Stair Railings

Brush-on Presto Black® Gel, Antique Black® Gel, and Antique Brown® Gel are solutions for use in-place architectural metal surfaces to produce a natural, aged metal appearance. Without runs or drips, surface in vertical or horizontal position can be converted to a beautiful silver/black wrought iron or antiqued finished look.

Ideal for most metal surfaces including iron, steel, copper, brass, bronze and other metals, the Presto Black Gel, Antique Black Gel, and Antique Brown Gel are simple and safe to use. Applied at room temperature, the gel adheres to vertical surfaces and stays where applied without forming runs or drips or bleeding onto adjoining surfaces.

These Gel finishes are the perfect solution when you can’t or don’t want to dip the entire part into a liquid bath container. They’re great for sheet metal that needs only partial blackening, for touching up parts and for adding finish to machined components.

The Presto Black Gel, Antique Black Gel, and Antique Brown Gel chemical reaction takes only 5 to 10 minutes following surface cleaning to remove oil, oxides and welding flux. Color tone and depth is easily controlled by visual inspection and stopping the process by rinsing off with a wet sponge and sealing the finished surface. It’s that easy.

Another nice feature is that the Gel finishes can be highlighted or distressed to achieve a distressed look. A final step to protect the finish and enhance the appearance is to add a clear topcoat such as a satin-gloss urethane lacquer or paste wax.

Presto Black Gel, Antique Black Gel, and Antique Brown Gel are user proven by building contractors, metal manufacturers and do-it-yourselfers on various projects. A broad range of applications include building facade, fascia, elevator cabs, staircase railings and handrails, sculpture, monuments, and window hardware.
