Painting ceiling after water leak

Are the spray stain things any good? Do you still need to paint over after use?
On the balance of probability, the white in the spray can will be a different shade of white, and possibly, a different sheen level.
I would add that spray cans can result in a lot of dry over spray (dust).
As decorator, I use brush applied stain blockers because of the over spray.
If you have the original emulsion, you might be able to get away with touching in the emulsion after using the stain blocker, but if the ceiling paint has discoloured, you may need to paint the whole ceiling.

We had a leak from a failed chimney flashing
Once repaired I left the ceiling to dry for a few months
I used zinsser stainblock from screwfix followed by a top coat of regular emulsion.
After around 3 years the stain has began to bleed through in places.

I tend to use the shellac based Zinsser BIN. Over the years, I have never noticed it discolouring further down the line. In the event of new leaks, the stains may become visible on the outer edges of the BIN. If the water ingress is significant, the salts in the plaster normally blister and push the paint away from the plaster.

Yes but the roofspace is now bone dry after the new flashing was installed.
