Hello,

Have a brown water stain on ceiling from an ice dam leakage.
Not very big; perhaps 2 inches or so wide X 10 inches long.

Ceiling is presently painted a pretty much Flat White.

I plan on very lightly sanding the stain, and then applying
Kilz Original Oil Based Primer-Sealer to it.

Question: is it likely that a single coat of a Flat White regular interior
Latex paint will blend in and hide
the Kilz "well," or do you think the oil based Kilz painted area will look
shiny (or otherwise be discernable) thru the single Latex coat ?

Thoughts and suggestions would be appreciated.

Thanks,
Bob
