Method for repairing wall crack of building

Abstract

The invention provides a method for repairing a wall crack of a building. Firstly, impurity removal and wall surface shoveling are carried out on the position, where the crack is generated, of the wall surface, then puttying is carried out, a bottom material is applied, and an adhesive is applied on the cleaned outer wall surface; then smaller holes and crack are filled up, and drying is carried out for more than 12 hours; then fine mesh gauze is used for binding the crack, the fine mesh gauze is roller-coated with a waterproof binder, and finally, after roller-coating of a primer is completed, finish paint is sprayed. If an empty drum is generated on the wall surface, repairing padding is injected into the empty drum of the wall crack, and after an empty drum groove is filled and leveledup, a crack-sealer is used for leveling the empty drum and the wall surface. The method for efficiently and rapidly repairing the wall crack has the advantages that the manpower can be effectively saved, the construction period is not delayed, the repairing effect of the crack is good, and the empty drum cannot be generated and the calcimine cannot peel off after repairing is completed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a method for repairing cracks in a building wall. Background technique [0002] The decoration of the wall plays a decisive role in the whole building decoration. At present, there are many kinds of coatings used in the decoration process of exterior walls, but they have poor stain resistance and high temperature resistance; High resource consumption, complex process, easy to pollute the environment, and pose a threat to people's health. In addition, the unreasonable process arrangement leads to the extension of the construction period and increases the decoration cost. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the defects in the above-mentioned prior art, and propose a method for repairing cracks in building walls. [0004] In order to solve the problems of the technologies described above, ...
