Stucco repair method for enclosing brick walls

During the operation of buildings, plaster coatings of the external and internal enclosing surfaces of brick walls are subjected to various destructive influences. Existing methods of repairing plaster coatings do not fully ensure strong adhesion of the material of the repair layer of plaster to the surface of the repaired brick wall structure. In addition, these methods can only get rid of damage but do not improve the operational properties of the plaster layer of the repaired structure. Thus, the urgent problem is the development of an effective method of repairing plaster coatings on the surfaces of brick walls, due to which it will become possible to ensure the monolithic of the repaired plastering structure. In order to address the shortcomings of the existing plaster coating repair techniques on the surfaces of the brick walls and finding ways to improve it, by the authors investigated the possibility and the expediency of performing the repair of additional process steps. A feature of this repair method is the use of preheated plaster mortar, flexible plaster molding, as well as compaction of the stucco mortar in the contact area with the repaired brick wall structure with a deep plate compactor. The test results of samples of plaster coatings manufactured by the proposed method showed the high efficiency and feasibility of using this method for repairs on the external and internal surfaces of walling of brick walls and are mentioned in the patent for the invention of the Russian Federation. The performance characteristics of the plaster are significantly increased as a result of the application of this method, and, consequently, the service life of the plaster coating is increased several times.
