Nowadays, there are many buildings in the city in summer. There is a feeling of "trying to compete with the heavenly Father". In fact, the construction of these buildings can not be separated from the use of external wall thermal insulation mortar. The external wall thermal insulation mortar can not only maintain the inner layer materials, making the construction more solid and solid, but also make the construction surface smooth and smooth with waterproof function.
Jinan plastering mortar Co., Ltd. takes us to understand the construction process of exterior wall thermal insulation mortar:
1. The external wall thermal insulation mortar shall be mixed with water for 1:2 before application, and shall be applied immediately after mixing.
2. In order to ensure that the surface is clean, flat and free of oil stains before construction, some floating, broken, loose and weathered parts should also be eradicated in advance.
3. The concrete wall and block wall shall be coated with mortar powder during construction. When the first layer is altered, the thickness shall not be greater than 10 mm. In the future, the thickness of each layer shall not be greater than 20 mm. The two construction hours shall be more than 24 hours away.
4. In the anti crack layer, the metal mesh is used instead of the mesh cloth as the reinforcing framework to make it connected firmly. Only when the insulation layer is monotonous can the anti crack insulation construction be stopped in the future.
5. Before the insulation layer and maintenance layer are monotonous, avoid water flushing, bumping and vibration. The construction of the two should be in accordance with the national standard planning, the construction thickness is not allowed to have negative error.
In addition, it should be noted that the water content of the sand should be controlled when the external wall thermal insulation mortar is consumed, because if the water content of the sand is too high, the sand is particularly simple to bond into a group, and the sand particles are more likely to bet on the screen, which will eventually lead to the reduction of screening efficiency. Therefore, as long as all these are ready, the mortar construction can be completed smoothly.
