Jinan plastering mortar for thermal insulation and crack resistance of exterior wall is an insulation system composed of fillers, polymer cement and sand additives according to a certain proportion formula, which can meet the requirements of some deformation without crack of polymer mortar, applying and constructing insulation layer, and forming crack resistance protective layer together with mesh or steel mesh. Let's talk about the amount of anti crack plaster mortar.
In ceramic microsphere and exterior wall external thermal insulation system, we know that according to the surface materials, it is divided into finishing coat and brick facing system, but the requirements of two different finishing systems for crack protection layer are also different. The grid cloth of crack in coating and surface decoration system is the protection layer for alkali grid cloth, and the thickness of crack resistance protection layer shall be greater than 3 mm, and shall not be greater than 6 mm. The protection layer and crack shall be in the brick veneer system. For hot-dip galvanized welded steel wire mesh or gridding cloth alkali gridding cloth, the thickness of anti crack protective layer shall be greater than 7 mm, and shall not be greater than 10 mm, therefore, the actual number of anti crack mortar different completion systems are also different. Compared with the coating system, the consumption of the brick coating system is larger. Generally, it is required that the construction thickness of single layer mesh anti crack mortar is 3-5mm, the construction thickness of the first layer of double layer mesh anti crack mortar is 3-4mm, and the construction thickness of the second layer mesh is 3-4mm. The number of users of steel mesh anti crack mortar is the same as that of double-layer grid construction, with the construction quantity of 3-4mm each time, 2 times in total.
In order to ensure the quality of anti crack protective layer, the construction thickness of anti crack mortar must meet the relevant requirements. How to control the cost of anti crack mortar waste in the construction can be seen as "how to save and control the amount of anti crack mortar".
