TECU® Patina – initial variations & natural weathering
1) What is TECU® Patina?
TECU® Patina has a crystalline surface that is a close as possible to that of naturally-aged copper.
In a patented process, the copper sheets develop, in just a few weeks, the living patina surface which
takes many years on the roof, and many decades on a façade.
The Patina surface develops on top of an oxidised layer, which protects the base copper sheet below.
Over time, the Patina surface continues to develop, providing lasting colour.

TECU® Patina – initial variations & natural weathering
2) Initial appearance of TECU® Patina
What makes it unique?
TECU® Patina is not a „flat‟, „static‟ or painted surface:
A natural surface like copper, TECU® Patina always adapts to its surroundings, site location,
exposure, etc.
Viewed close-up, you can see variations in the surface when new.
Colours can vary: TECU® Patina in the Alps will be different to TECU® Patina in the city, or TECU®
Patina by the coast.

* TECU® Patina hand-processed is an option designed for manual post-patination of individual pre-fabricated (3D) items, rather than sheet materials.

3) Project images, showing acclimatisation of TECU® Patina
The surface of TECU® Patina sheets corresponds to that of a naturally evolved copper patina. Colour
variations are an ordinary and desired part of the patination process, as they emphasise the natural
qualities of the product and the individual character of each sheet.
Differences between sheets, varying from tones of yellow-green to blue-green, are gradually evened
out over time as a result of exposure to weathering.
They are not an indication of varying quality, but a mark of the product‟s unique natural qualities.
