Abstract

The invention belongs to the field of building construction, and provides a method for renovating an external wall of an existing building. The method at least includes the external wall effect constructing step, the window side filler and waterproofing step and the parapet external corner treatment step. By means of the renovating method, the existing building can continue to be used for a longertime, and building energy conservation is realized. Moreover, the external wall renovated through the method has a smooth base layer and a good appearance effect. The problem that the junctures of different materials at window frame joints are prone to cracks is solved, and therefore the water seepage and water leakage potential hazards in the later period are eradicated, the water leakage of window sides in the later period can be effectively avoided, and the complaints of owners in the later period and the cost for property maintenance are reduced.
