Hello, I have touched up my ceiling over an area of about 60 x 60 cm with flat white paint and the color blends in, mostly. But, if I look at the patch from a certain angle with low amount of light in the room, the newly painted area becomes obvious. I think it's what people call "flashing". I've been contemplating to repaint the entire ceiling. Would repainting my entire ceiling remove the "flashing" or would I risk creating even more "flashing" patches?
Don't look up Give it a week once you stop looking at it, then go back and have a look. 90% chance it won't stand out as much
Repainting will hide it. Otherwise you can feather edges by running roller dry to blend it progressively
I'd first have to consider what room it is. I once rented a house where I damaged the ceiling both in the lounge room and the bedroom. I kid you not, the first inspection by PM and the damage in the lounge room ceiling was picked up straight away. The damage in the bedroom wasn't picked till over a year later! So if it's in the lounge room etc , yes fix it. Anywhere else pfftt.
