What is the thickness requirement of general external wall plastering?
1. Wall condition: Uneven wall will affect the thickness of plastering mortar. If the wall is flat, you can use thinner mortar; If the wall is uneven, it needs to be trimmed with thick mortar.
2. Insulation layer thickness: Exterior wall insulation plastering mortar is mostly used to cover the insulation layer, and the thickness of insulation layer will directly affect the thickness of plastering mortar. Generally speaking, the insulation layer thickness is 3-8 cm, and the corresponding plastering mortar thickness is about 2-3 cm.
3. Design requirements: According to the requirements and specifications of architectural design, there are sometimes specific provisions on the thickness of external wall thermal insulation plastering mortar. For example, in some countries or regions, the range of minimum thickness and maximum thickness may be stipulated in the architectural design code, and construction needs to be carried out in accordance with relevant regulations.
4. Environmental factors: The thickness of plastering mortar for external wall insulation is also affected by environmental factors, such as climatic conditions and the location of the building. Cold and humid climate conditions may require the use of thick plastering mortar to increase waterproof performance and thermal insulation effect.
It should be noted that the above is only a reference value in general, and the optimum plastering mortar thickness should be determined according to the specific situation and relevant regulations in the actual construction process. In the construction of external wall thermal insulation plastering mortar, it is recommended to consult professionals and carry out construction operations in strict accordance with relevant specifications and requirements.
