It is worth mentioning that any kind of putty lies equally on almost any surface. With a small trowel experts distribute a small amount of the construction mixture and distribute it evenly over the surface of a wide trowel. Then the mixture is applied with a wide trowel to the ceiling as thin and uniform layer as possible. The remains of the mixture from the wide spatula are removed by the narrow one back into the basin. This procedure continues until the entire ceiling has been putty in the first layer.
For the final stage of processing, use water-resistant putty, which does not get soaked by the water contained in the paint and will hold firmly to the ceiling. You can also add a water repellent primer to a regular putty to dilute the putty mixture.
