The Finishing Touch for Ceiling Repairs
After you’ve completed the above outlined steps on repairing small or large cracks in the ceiling, you’ve allowed the necessary time to let it all dry, apply the paint primer and then paint the ceiling.
Painting the ceiling in it’s entirety will only be required if it’s the large patch you’ve repaired. It also depends on how old the paint on the ceiling is. If it’s been a few years it’s definitely a repaint of the whole ceiling.
For the smaller repair of the ceiling, the same painting advice applies. Where you can simply paint the small patched area of the ceiling if it’s been a recent painting job. If a few years have passed then if you don’t repaint the entire ceiling you’ll be able to see the difference in the paint colour.
