Background
A large number of existing old residential building in China are red brick (sintered clay brick) structures, the outer wall of each red brick can be damaged in different degrees after being blown by wind, blown by rain and drenched for many years, the color and luster of the outer wall of each red brick can also become dull, and the red brick structure is the key content for the transformation of old residential areas. In the existing old community transformation in China, the transformation is usually carried out by adopting a method of adopting an external facing of real stone paint or texture paint or a method of adopting a soft stone facing, for example, CN 11622365U discloses a layer structure of external wall texture paint, which comprises a base layer, a putty layer, a relief layer, a texture paint layer, a filling layer and a protective surface layer which are sequentially arranged from inside to outside; the texture is enhanced through the concave grains of the relief layer, so that the three-dimensional effect of the wall surface is stronger, the texture of the texture can be further enhanced through the texture paint layer, and the overall texture is better.
The method of adopting the exterior finish of the real stone paint or the texture paint can not better restore the exterior wall surface of the clay brick sintered in the old residential area and can not better keep the historical appearance of the building. The method of soft stone facing has long construction period and high cost, and is not suitable for old community reconstruction projects with tight construction period and low cost.
