a local repair or prior coating needs preparation before a new finish is considered. Protect the room and fixed fixtures, prepare the accepted sound surface and paint the agreed ceiling plane in suitable stages.
Signs: the surface is scuffed, patchy, weathered or no longer presents evenly or the existing finish shows ordinary wear that may suit bounded maintenance. Causes: incompatible or unknown prior finishes that need checking or surface damage that needs preparation before finishing.
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.
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.
Allow the specified drying and ventilation before reopening the room. Any remaining substrate or lighting-related finish limitation should be discussed. Limits: Ordinary dry stable accessible ceilings only. No electrical fixture work, leak diagnosis, sagging ceilings, high-access specialist work or hazardous materials.
