Exterior wall coating construction process

One, high-level wall waterproofing leakage

Walls are vertical components of the building, but due to the design, construction, materials, use and other factors will cause cracks in the wall, resulting in leakage.

Wall leakage cure:

Repair of the original structure of waterproofing using linear structure waterproofing, its function is to make the water dispersion. Cavity construction localized damage, the use of restorative repair is better.

Repair with waterproofing materials:

This method is widely used, that is, in the rainwater penetration of indoor parts of the use of oil-soluble or water-emulsion waterproofing materials embedded joints or painting method. Waterproofing measures are taken on the outside of the exterior wall panels, and the wall is waterproofed by waterproofing materials.

Exterior wall inside coating water blocking method:

That is, half of the inner side of the exterior wall to take waterproofing measures, through waterproofing materials to block rainwater intrusion.

Construction of strong high-altitude work on all types of waterproofing repair works have professional and technical staff to investigate the site, demolition, and development of construction plans. Therefore, the waterproofing of high-rise exterior wall leakage does not need to set up scaffolding, saving auxiliary expenditure.

Second, exterior wall coating construction

New wall coating construction:

The bottom layer of the building exterior wall coating requirements for a sufficient maintenance period, the new water mortar concrete surface must be maintained by a fair amount of time, so that it "spit alkali", sufficiently dry. Sufficiently dry. The surface of the substrate should be dry, solid, firm, there should be no sand, cracks, loose and other defects.

Construction method:

Exterior wall painting should not be large area scraping putty, putty layer should not be too thick, the material uses polymer cement putty. Generally use a primer, two surface coating construction. According to the project quality requirements can be appropriate to increase the number of surface coating. Painting construction is generally carried out from top to bottom, each painting should be divided into lines, walls, yin and Yang corner junction or downpipe as a boundary.

Manipulation tools:

General roller coating, brush coating or air spray and airless spray.

Maintenance renovation:

The use of paint on the surface of the building decoration, the greatest strength is to be able to renovate within a certain period of time, generally in 4-5 years on the building of comprehensive maintenance. The renovation of the exterior wall surface before the construction of a comprehensive and comprehensive examination, the development of construction plans.

On completion of the finishing project, the customer will be long-term quality tracking, return visits, and provide painting maintenance program.

Three, building curtain wall glass repair

Exterior wall decoration using glass curtain wall, the quality of the difficulty, so the process requires rigorous, necessary to ensure the quality of the project.

Curtain wall glass repair project after years of practice, the need to form a set of scientific process and coordination of the installation process. Installation of the use of sealant in the structural adhesive and weathering adhesive (preferably using the entrance glue), gluing smooth, clear lines, no leakage. Curtain wall glass in strict accordance with the design requirements of material selection.
