To make the ceiling even, you need to remove the old coating. This stage must be done, no matter what repair was. If the ceiling had a drywall or suspension system, then you should determine the condition of the frame and layer that needs to be leveled.
Using a level, it is necessary to determine the actual difference in the structure or ceiling in general. Then you need the surface to cover how it will depend on the alignment method, which is selected. It is necessary to clean the ceiling well, roll it and primer.
If the difference is more than five centimeters, then the ceiling must be plastered, after which it is putty. Putty should be applied in several layers before applying the subsequent layer, the previous one must dry thoroughly.
After the level of the ceiling difference in one room is determined, you need to try to choose the method of preparing the surface for the final finish.
How to align the ceiling with your own hands, which method to choose, is determined by the difference in the ceiling. For example, the dry alignment method is used if at least in one place the difference exceeds five centimeters. Dry method involves the use of drywall or gypsum fiber. For the installation of public premises, amstrong ceilings will be used. It became also popular to make stretch ceilings. It is much simpler and faster than to align the curve ceiling.
If the difference is less than five centimeters, then they use the “raw” method. Namely, the ceiling must be plastered, with the help of special mixtures, it is tanned and prepared for the final painting.
