Achieve a Flawless Black Finish with Birchwood Technologies Presto Black BST4 Brush-On Liquid

Transform the appearance of your metalwork with the Presto Black BST4 Brush-On Liquid, a game-changing solution from Birchwood Technologies. This innovative product is specifically designed for all iron and non-stainless steels, allowing you to achieve a stunning, non-dimensional black finish in just 30-90 seconds. The reaction occurs at room temperature, making it easy to apply using either swab-on or spray techniques.

Whether you're a professional working on precision tooling and machine components or an enthusiast creating decorative metalwork, architectural trim, or hand-forged items, this product is an absolute must-have. The resulting finish can be sealed with a protective oil, ensuring durability and longevity. Alternatively, you can highlight the black finish to produce a unique, distressed or antique pewter type finish, adding an extra layer of elegance to your creations.

Before applying the Presto Black BST4, it's essential to thoroughly clean the metal surface of all oil and excess scale. Use a solvent that doesn't leave a residue, such as alcohol, acetone, or lacquer thinner, to prepare the surface. Remove any oxides using bead blasting, Scotchbrite abrasive pads, or flap wheels. Then, apply the BST4 solution in a thin film, replenishing the solution as needed to achieve a uniform gray/black finish.

To stop the reaction and prevent flash rusting, sponge the surface with water to remove blackening residues. For added protection, consider applying a baking soda solution to neutralize any remaining chemicals. Force dry the surface with compressed air or warm air, and finally, seal the surface with a topcoat suited to the article's intended use. For tooling and machine parts, use a water-displacer like DRI TOUCH AMBER IRP2. For decorative surfaces, highlight with Scotchbrite pads and seal with a clear, satin lacquer, or use paste wax for light-duty, indoor pieces.

With Presto Black BST4, you can unlock endless possibilities for your metalwork projects. Whether you're a seasoned expert or a budding enthusiast, this product is easy to use and provides consistent, professional-grade results. From precision tooling to decorative metalwork, this innovative liquid blackener is the perfect addition to your toolkit.

By choosing Birchwood Technologies' Presto Black BST4 Brush-On Liquid, you're not only ensuring a flawless finish but also tapping into decades of industry expertise and dedication to quality.
