we had a small leak in our condo and now theres a yellowish patch on the ceiling.
anyone know what sort of quick fix, paint or paint code i should use to paint it back to white?
thanks

hit it with some kilz first, something like this https://www.homedepot.ca/en/home/p.upshot-interior-overhead-stain-sealer---284g.1000139629.html

then you can use reg white paint if you choose

however youll be able to see its not matched with the rest of the ceiling. At least it wont look yellow

As Faline said, yes first use a primer such as Kilz to block the stain from showing through.

Then buy ceiling paint. They are all flat white - it is the standard. You can ask them to add a couple drops (1-2) of yellow oxide colorant to allow for better coverage and then paint the whole ceiling.

np, note that when you paint the ceiling, you should go in one direction for the first coat (up-down). And the second coat will be going side-to-side (left-right).
