Kilz/Zinsser Mold/Mildew Primer (Upper Bronx NE/Lower Yonkers)

If you happen to have any good condition Kilz/Zinsser Mold & Mildew Killer White Primer or similar quality primer, at least 1/2 gallon, please contact me via this site. Unfortunately, my landlord doesn't provide this service even though he should for my kitchen and bathroom ceiling that recently had some leaks. TIA.
