在GRC轻质墙板表面的钢丝网上进行装饰抹灰时，约束抹灰层收缩变形的是钢丝网和聚苯板，但钢丝网在施工时不易拉平，隔墙板受力后又易发生变形，消弱了抹灰层的约束能力，易出现收缩裂缝，使墙体发生结露现象。可以采用严格分层抹灰，且两次抹灰时间间隔在7d以上，待上层抹灰充分收缩和变形后再进行下一层抹灰的施工方法，即可改善后续抹灰层的约束条件，有效的预防收缩裂缝和结露现象的发生。
When decorative plastering is carried out on the Steel Wire Mesh on the surface of GRC lightweight wall panel, the Steel Wire Mesh and polystyrene board are used to restrict the shrinkage deformation of the plastering layer, but the steel wire Mesh is not easy to flatten during construction, and the partition board is prone to deformation after being subjected to force, weakened the plastering layer of the binding capacity, prone to shrinkage cracks, so that the wall condensation phenomenon. The restrictive conditions of the subsequent plastering layer can be improved by strictly layering plastering, and the time interval between plastering is more than 7 days, and after the upper plastering layer has fully contracted and deformed, the construction method of the next plastering layer can be carried out, effective prevention of shrinkage cracks and condensation phenomenon.
