Who should I apply to change the external wall?

1. The back wall of the frame structure can be changed. The external wall of brick-concrete structure cannot be changed. First of all, you should apply to the property management office of your community. The load-bearing wall is not allowed to move, but the filler wall can.

2. Unless it is a wall built behind the frame structure, it can be called a non-load-bearing external wall. If the following wall can be rebuilt, it is best to find the property department to declare the demolition and reconstruction project, and the property will tell you whether it can be rebuilt. Only from the language, no one can see whether the actual situation is a load-bearing wall. Anyone's suggestion is just a reference, and the management department will issue an approval.

3. There is no need to shovel tiles for the renovation of the external wall of the old house, but the external wall tiles must reach the specified tensile strength. Dismantle the outer wall brick at the empty drum, plaster it, use special flexible putty for the outer wall, mainly use adhesive for the wall brick and putty, then use anti-crack leveling putty, use waterproof putty for the surface layer, polish it (it is difficult to polish it as soon as possible after drying, and it is difficult to polish it after encountering water), and finally brush the primer and the topcoat twice.
