As is well known, additional heat insulated façades require regular maintenance. Thus, the installation instructions for synthetic plaster state that the protective layer of plaster should be renewed approximately every 7 years, i.e. cleaned and repainted, which ensures its preservation for many years. It is a quite cumbersome and expensive endeavour – but it is inevitable. In this case, costs per m2 range from 15 – 25 EUR.
In the case of a Marmoroc façade, it is sufficient to clean the façade with a pressure washer. In December 2015, 10 years ago, we performed cleaning services for a Marmoroc façade installed in an five-story apartment building in Keila, Pae 4. For this work we used a Dino aerial work platform and a pressure washer. Dirtier areas were washed simply with harder pressure or by standing closer. The result was brilliant. The house looked like new and it only cost about 1 EUR / m2.
Therefore, when choosing façade insulation, it is definitely worth thinking about how the chosen insulation system behaves over a longer period, what periodic maintenance it needs, and what costs this entails for the apartment association.
