Why did the ceiling fall off? How to deal with it? 1. Reasons for peeling 1. When the temperature is too low to paint the wall with latex paint, if the space temperature is low at that time, the coating film with the latex paint will not have continuity, so the latex paint will crack after brushing, and the wall will peel off seriously Problems will naturally arise. Happens if it encounters water. 2. The base layer is loose and the putty strength is low. If the base layer has oil stains and other dirt, the coating and the base layer cannot be well combined, and the wall will peel off. The putty used for the base layer is not particularly strong. ----Aluminum curtain wall panel manufacturers

If the putty layer needs to be coated with latex paint before it dries completely, the base layer will be too smooth to adhere to the film better, and there will be problems of peeling. 3. Process error Before construction, the base of the ceiling should be wetted with water, and cement can be used during construction. This practice can well prevent the moisture in the base layer from being absorbed by the cement, making the base layer dry prematurely, making the bonding effect of the cement mortar worse, and causing serious shedding problems. ----Aluminum ceiling manufacturers
