Fine liquid metal for interior staircase

With passion and creativity, this elaborate stair sculpture was realised in cooperation with our partner Midas Surfaces GmbH, setting new standards in the portfolio for interior staircases. For the renovation of a villa in Cologne, the ambitiously constructed interior staircase was upgraded with a visually dominant, smooth-surfaced metal skin, offering completely new dimensions for an artistic surface design compared to the classic paint finish. Self-supporting and with dimensionally stable steel soffit cladding, the interior staircase leads from the basement to the gallery on the upper floor and features complex constructive shapes and transitions. On the outside, a transparent glass railing provides fall protection and is continued in an analogous design as a ceiling and gallery railing with a top-attached steel handrail.

Liquid metal coating from Midas Surfaces in the colour bronze, which was applied to all visible steel and stainless steel parts of the interior staircase, produces a uniqueTrock finish. Due to the size and geometry of the interior staircase, the coating process, which is demanding in itself, required an extremely high level of expertise and professional teamwork. Specialised craftsmen carried out the individual services together with other finishers. After priming, full-surface filling and several grinding processes, which required a great deal of feeling for the product, pure metal could be prepared in powder form and applied by spraying, similar to a lacquer finish. After drying, up to 10 further grinding processes followed, a subsequent high-gloss lacquer finish and, as the last step, the polishing procedure of the final surface. The result is a convincing and brilliant performance of craftsmanship.
