First, the high-rise wall waterproofing trap: the wall is the vertical component of the building, but due to design, construction, materials, use and other factors will cause the wall to crack, resulting in leakage.
The method of leaking the wall: repairing the original structure waterproofing adopts the linear structure waterproofing, and its function is to disperse the water.
When the cavity structure is partially damaged, the recovery repair effect is better.
Repair with waterproof material: This method is applicable to a wide range of applications, that is, the use of oil-soluble or water-based waterproof material caulking or painting in the interior of rainwater.
Take waterproof measures on the outside of the siding.
The method of blocking the water in the outer wall is to take waterproof measures on the inner side of the outer wall and block the intrusion of rainwater through the waterproof material.
Second, the exterior wall surface architectural coating construction: new wall coating construction: the bottom layer of the building exterior wall coating requires sufficient curing period, the new water mortar concrete surface must undergo reasonable curing time, let it "soda", fully dry . The surface of the bottom layer should be dry, firm and firm, and should not have defects such as sanding, cracking and loosening.
Construction method: It is not advisable to apply a large area to put the putty on the outer wall. The putty layer should not be too thick. The material is made of polymer cement putty. Generally, the primer is applied once and the surface is applied twice. According to the quality requirements of the project, the number of surface coatings can be appropriately increased. Painting construction is generally carried out from top to bottom, and each application should be bounded by a dividing line, a wall surface, a junction of the yin and yang corners or a downpipe.
Operating tools: generally used roller, brush or air and airless spray.
Maintenance refurbishment: The use of paint to decorate the surface of the building, the biggest advantage is that it can be refurbished within a certain period of time, generally comprehensive maintenance of the building in 4-5 years. Conduct a comprehensive comprehensive investigation before the renovation of the exterior wall surface and formulate a construction plan.
