Fiber cement external wall hanging board is made of imported high-end cement as raw material supplemented with plant and mineral fiber. It is specially used for the construction of high-rise building walls. It can also be called fiber cement board and fiber cement pressure plate. Cement external wall hanging board used in high-rise buildings, may be due to its design, construction, material and other factors, because of its wall cracks, leading to leakage. So what waterproof measures does fiber cement external wall hanging board have? I have collected some common knowledge of construction, and I would like to share them with you!

1、 When the cavity structure is partially damaged, the restorative repair is better.

Repair with waterproof materials: this method is applicable to a wide range of areas, that is, oil soluble or water emulsion waterproof materials are used for caulking or brushing in the parts where rainwater infiltrates into the room.

Waterproof measures shall be taken outside the hanging board of fiber cement external wall.

External wall internal coating water blocking method: that is, waterproof measures are taken on the half inner side of the outer wall, and the rainwater intrusion is blocked by waterproof materials.

2、 Construction of exterior wall architectural coating: Construction of new wall coating: sufficient maintenance period is required for the bottom layer of external wall hanging plate coating

The new water mortar concrete surface must pass through the reasonable curing time, let it "spit alkali", fully dry. The surface of the bottom layer shall be dry, solid and firm, and there shall be no defects such as sanding, cracks and looseness.

Construction method: it is not suitable to apply putty in large area for exterior wall painting, and the putty layer should not be too thick. The material is polymer cement putty. Generally, one primer and two top coats are used. According to the engineering quality requirements, the surface coating times can be increased appropriately. The coating construction is generally carried out from top to bottom, and each painting shall be bounded by dividing line, wall surface, joint of internal and external corners or downpipe.

The construction method is that the exterior wall coating can not be too much putty, and should not be too thick. Generally, the material is one coat of primer and two times of surface coating. The tools used are roller coating, brush coating or air spraying and airless spraying.

Cement external wall hanging board we usually see in the building is the feeling of tall, a long time will inevitably have broken or water seepage phenomenon, so we need to master and understand these waterproof construction methods, especially the building developers, so as to ensure that the cement external wall hanging board can serve the building for a longer time, making the board bright as new.
