What is the practice of plastering and sealing windows?
1. If the window is to be plastered and closed, the vertical line must be put back before closing and checked. If the position, verticality and levelness of the vertical line do not meet the relevant construction requirements, then the chief foreman shall be informed.
2, only after the main foreman qualified, can start the next construction process. If the window is blindly used as the control line to close the mouth, it will generally lead to rework, and all construction workers need to bear their own responsibilities.
3. Before plastering the window, clean up the sundries and dust at the window closing place, and sprinkle water for wetting. After wetting, cement mortar should be prepared according to the ratio of 1:2, and then the prepared cement mortar should be plastered in layers to close the window.
4. When plastering and closing the window, generally use cement mortar to press the aluminum alloy window frame on the outside of the window about 5 mm ~ 8 mm. After plastering the window, make sure that the finished window frame is exposed about 18mm ~ 12mm, and the drain hole of the lower stile must be exposed for drainage. In addition, the windows on the facade must be on the same straight line, and the facade size of the hole must be vertical and square.
5. The window opening on the plastering surface inside the window can't have a slope, and the indoor windowsill part is about 3mm ~ 5mm higher than the outdoor windowsill root, which means that the inner windowsill must be higher than the outer windowsill, and it must have a square size.
