Verzinkshop Black Brown Copper Patina works on copper, brass and bronze. The patina on brass and copper gives a satin black-brown to deep black patina effect and with the patina on bronze the color is lighter. Ideal for fittings, restoration and project work such as accents on fa\u00e7ade panels, wall panels, fa\u00e7ade cladding\/wall cladding and metal sheet metal for interior\/fa\u00e7ade. The concentrate is easy to dilute and delivers consistent, reproducible results. Do you want a dark black patina? Then maintain a stronger mixing ratio. <\/p>\n

Dilute 5 to 20% with distilled water<\/a>. Example with 100 ml concentrate:<\/p>\n Tip: always test on a test piece of the same metal and with the same (polishing) finish.<\/p>\n <\/p>\n <\/p>\n Patina is a controlled discoloration of the metal surface. By chemically patinating you accelerate the natural aging process and determine the depth, nuance and direction of the color. Finishing (brushing, light polishing) and sealing determine the final appearance and maintenance. <\/p>\n The process for our patinas is similar. Take a look at a quick example on brass: <\/p>\n\n
