Hello,

I have a water stain (brownish) on my bathroom ceiling.
Problem has been corrected, and I don't expect a repeat.

Would like to put Kilz Primer/Sealer over the stain.
Since I don't expect any further leakage, can I use a water based Kilz
instead of their oil based product ?

Or, would the brownish stain would eventually bleed thru any water
based Kilz, even though the stain is dry now ?

That's what primer does - cover stains. It is irrelevant what the base of
the primer is.

kilz oil based primer appears to work better
