Birchwood Presto Black SSB Stainless Steel Blackener – Cold Brush-On Patina (8 oz)

Birchwood’s Presto Black SSB is a cold brush-on stainless steel blackening solution designed to deliver a deep, even black patina on a range of stainless alloys. It’s crafted for both creative experimentation and practical touch-ups, offering a versatile path from clean metal to a refined, dark finish without heat or harsh chemicals.

Key benefits at a glance

• Deep black patina on stainless steels, including 304, 316, 410, and 17-4, with consistent color across surfaces.
• Works across stainless families, enabling a cohesive look on mixed components or projects.
• Made in the USA; Birchwood has served architects, artists, and industry since 1948.
• Artistic techniques enable customization—immerse, swab, or spray for patterns and a distressed highlight.
• Fast-acting formula; color begins developing instantly on clean steel, making small projects quick to complete.

Versatile application and finishes

• Immersion, swab-on, or spray methods provide flexibility for large panels, complex geometries, or tight corners.
• Highlighting after application yields a pleasing distressed appearance for one-of-a-kind results.
• Seal with a compatible topcoat (oil, wax, clear coat, lacquer) to suit your end use and protection needs.
• Pair with a metal cleaner and rust preventative to build a DIY black oxide kit for stainless steel.

Usage, safety, and care

Surface should be clean and dry before application. PPE is recommended—gloves and safety glasses; respiratory protection may be needed if spraying creates a mist.

What you can expect

This finish offers a versatile, creative option for adding a bold, modern or vintage look to stainless steel projects. The 8 oz bottle provides a compact solution for touch-ups or larger builds, with a finish that can be sealed to protect the patina over time.
