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.
Windows and directional light can make existing ceiling texture or repair edges more visible. Include a photograph in ordinary room lighting. A repaint can improve a sound surface but should not promise to remove underlying unevenness or make every previous repair invisible.
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.
