Rust has to be removed from the time axis in the pedestrian zone. Although the author of its artistic interpretation, Marian Karel, has certain notion of used material transformation due to climatic conditions, he admits that the rust should not spread onto the pavement or even damage it. At the meeting of town representatives with the designers from Atelier 69 - Architects and sculptor Marian Karel (author of the Gate of Time which should be installed at the division line of the pedestrian zone and the square in June at the latest) was agreed that both the time axis and the artefact will be covered with protective paint. It will not influence their patina but will just prevent further spreading the rust.

"We like natural materials for their ability of growing old in a natural way. Anyway, the rust distinctiveness of the time axis was an unpleasant surprise for us," Jaroslav Wertig, architect from A69 says. "The work on treatment the time axis will start immediately when climatic conditions allow it. After agreement with town representatives patinated metal segments will be used in stage II."
