How do I get rid of this painted out boarder that is on the ceiling. ?

I would repaint the ceiling in both rooms.

If the color looks different to you now, it will likely look worse to you if you put fresh paint anywhere near it. Asking do you have to have it sprayed again makes me think you have the spray texture on there? The right way to do that is to mix some paint into the texture to make it stick better when it is first applied. But few did that. You don't need to re- texture if it is still evenly coated, But it will be a bit harder to paint using a roller if that paint was not added because the texture will loosen as it gets wet & some will come off. You can tell if it is likely to cause trouble by getting up there & testing to see if the texture can be easily removed by rubbing your fingers over it. It is usually not enough to hurt if you paint it this way:

Buy a roller for rough surfaces. A fat, fuzzy one.

Buy more paint than you normally need for an area the size of your ceiling. This first time it will take more if that texture wants to loosen up. Once it is stuck down, it won't take that much when you repaint it. Use a stock color rather than one they mix st the store & you can return any you don't open.

Load your roller w/ a lot of paint & work in small areas at a time. Just get the paint on w/ as few back & forth passes as you can. If small spots aren't covered, or a little bit pulls off, just leave it to dry w/o trying to fill them in. You will only make it worse. Paint the whole ceiling & let it get completely dry.

Then, go back over the spots only w/ your roller. Do not paint a nice neat square but roll in all directions, leaving the edges uneven. It will hide your "patch" better. If the spots are very small & likely they will be, use a 4"brush rather than a roller. Again, leave the edges uneven.

The good thing, is once that ceiling has paint on it, it won't come loose the next time you paint.

As a painting contractor, I did have some textured ceilings I had to spray because the texture loosened up a lot trying a roller. They were very heavily textured. Way more than was usual. Likely yours is not like that.

Just remember to put the paint on heavily. Roll as little as possible. Don't touch up any of it until completely dry. Never had enough come loose to have to re-spray, so don't worry. It will be fine when you get it finished:)

If all you want to do is get rid of that border, choose a place that won't be noticeable & remove a slice of that texture to get a piece a couple inches in size. Take it to a store that offers custom tinting & have them match it. Painting the border, don't follow the line & cover only the border, but make your edges uneven. It will not show as much as a straight line will. Wise to paint a few feet to test. Let it dry & wait 24 hrs so you can see what it will look like in daylight & w/ the lights on when it gets dark. If the match suits you, you are good to go. If not, take the mixed paint, a sample on a piece of white poster board or scrap lumber & your chip back to the store so they can adjust the tint. Go ahead & paint as that border is so dark, 2 costs is likely to be needed. I would just use a 4" brush as I would want to keep the repaint small & still get the uneven edges Small is best when trying to get by w/o repainting the entire area. An even strip around the room painted w/ a roller may still leave you w/ a border effect. More subtle oolor, but still a visible line.

WOW! Too much info from Stevie. Use a thick nap roller for textured ceilings. Prime with Kilz primer. Then paint. Use a good ceiling paint. Most ceiling paints a flat. Semi gloss or gloss will show every imperfection. That's how I paint my textured ceiling.
