For planners · Surface protection
Every surface is available in three finishes. The choice decides whether the surface keeps developing or stays as delivered.
No protective layer follows the final treatment. The metal lies open and stays chemically responsive: it darkens, keeps building patina, and where someone touches it, perspiration leaves a mark. Grease and cleaning agents act on the surface too.
That is not a defect but the property of this finish. Choosing it means choosing a surface that keeps developing.
Suitable when the change is part of the design and the surface is not touched constantly.
A layer of wax sits over the metal and slows the exchange with the air. The development continues, but more slowly, and marks from handling come off more easily.
Wax is not a permanent barrier. It wears off and has to be renewed, otherwise the surface gradually approaches the unsealed state. In exchange the condition can be steered through care, which is not possible with the other two finishes.
Suitable when the surface is indoors and someone can look after it.
The lacquer closes the surface off. No oxygen reaches the metal after that, and the colour stays at the state of the day the surface left the workshop. The texture of the substrate remains visible, the reaction underneath stands still.
The price for that is finality: what has been sealed does not develop any further. A damaged lacquer layer cannot simply be renewed the way wax can.
Suitable when the surface should look unchanged for years.
The finish belongs in the tender text. Leaving it open may produce a surface that behaves differently from the one that was designed, and that only becomes apparent years later.
