Before you start painting, take out all the furniture out of the room. If this is not possible, cover it with polyethylene. On the floor, you also need to lay some kind of fragmentary material. All electrical installation products must be removed (chandeliers, lamps). In places where staining will not be carried out (in the places of connection of the walls and ceiling), it is necessary to glue the painting flight. Make sure that the paint is enough for you for the entire ceiling, and whether the temperature corresponds to the room.
