I. renovation step by step
The renovation process of the old building base has the following links: understand the project overview → inspect and repair the project → test the disease → put forward suggestions → construction scheme of exterior wall coating → preparation → construction process of exterior wall coating → acceptance
II. Planned renovation
First, we need to evaluate whether the existing walls need to be renovated through testing. Generally, manual visual inspection and percussion detection are used, that is, washing the wall with high-pressure water gun, inspecting the wall, marking and making written records. Then we can find the problems of the building base. According to different problems, adopt different treatment methods for maintenance.
After different methods are adopted for different problems, the wall condition and construction effect shall be evaluated again and then accepted. In the project requiring the whole wall renovation, it is recommended to use the qualified wanlei real stone paint for renovation, which can improve the overall appearance effect of the building. At the same time, the product system of fulet real stone paint is complete and the quality is stable, which can prolong the service life of the exterior wall and reduce the maintenance cost in the future.
