The existing finish, colour and selected product affect preparation and application stages. Discuss the complete system before supplying paint. Extra coverage may require a different plan, and applying a heavier coat is not a substitute for following drying and recoating instructions.
New patches can absorb paint differently from older surrounding areas. Show repaired spots so suitable preparation can be considered. Painting does not automatically include every plaster repair, and the need for sealing or further finishing should be identified before the coating stage.
Furniture and occupied-room access need planning around protection, ventilation and drying. Identify rooms that must remain available. Completion of application does not necessarily mean immediate ordinary use; reopening follows the selected product and actual conditions.
Protect the room and fixed fixtures, prepare the accepted sound surface and paint the agreed ceiling plane in suitable stages. Scope limits: Ordinary dry stable accessible ceilings only. No electrical fixture work, leak diagnosis, sagging ceilings, high-access specialist work or hazardous materials.
