The Fenix Palace on Wenceslas Square has two main entrances, one of which consists of a granite staircase. The roughened granite surface of the staircase was not maintained in any way for decades, only wiped by the cleaning service. In the middle of the staircase is the door to the kitchen of the restaurant, the staircase was contaminated with grease from the shoes of passing staff. In other places of the staircase, there were remnants of glue from a carpet that had once been glued. Using a Narran ROD1000 pulsed laser, we cleaned the staircase without having to close the passage and without interrupting the operation of the adjacent theater and café. www.lsrservices.cz
