Have you ever wondered when is the best time to do exterior wall cleaning and how many times a year should you do it?Next, we will reveal the best time and frequency for exterior wall cleaning.
If the building does not clean the exterior walls for a long time, the service life of the exterior walls will be shortened, and it may even lead to the early scrapping of the exterior walls. Therefore, exterior wall cleaning is an item that every unit needs to do every year. However, some units are cleaned twice a year, some only once a year, and some buildings are not cleaned even for years, leaving the exterior dirty.
In fact, it makes the most sense to clean the exterior walls twice a year. This frequency of cleaning prevents dirt from eroding the wall and does not form stubborn stains, keeping the exterior looking as good as new.
For the best time to choose the best time for exterior wall cleaning, a cleaning should be carried out before the rainy season, which can remove the sulfur dioxide adsorbed by the exterior wall in winter in time to avoid corrosion of the wall after fusion with summer acid rain. In addition, an exterior wall cleaning should be carried out at the end of autumn, which can remove the scale left by frequent rainwater in summer in time, and avoid merging with car exhaust in winter and forming stubborn stains.
Finally, it should be noted that exterior wall cleaning is a high-altitude operation, so it is necessary to choose a regular exterior wall cleaning company, a master with a high-altitude work certificate to operate, and ensure that the construction team pays attention to safe construction.
