I have almost a gallon of Kilz water based exterior primer that I don’t need elsewhere. I have put a new layer of mud on the walls of a small bathroom and need to seal it before painting with a good semi-gloss paint. Is that okay?

No… for baths which all receive lots of moisture you should prime with a Pigmented Shellac or Oil Base Primer…
