What is the difference between water base sealer and oil base sealer? My wall is mouldy, so which one should I use?

Suggest to use Oil Base. Basically, they are use to make your painting stick to your wall. Because once your wall become mouldy or peel, paint doesn't stick.

Oil base tend to be better in keeping water from coming in. Esp if your wall is near the window. And out of nowhere, you see rainwater coming in from somewhere you can't find even though your window is close. That's a leaking problem. And Oil sealer than to do better for such job.
