How Long Can Primer Sit before Painting?

Primer is essential for a good paint job, but how long can it sit before you start painting? If you’re using a water-based primer, it’s best to start painting within 24 hours. If you’re using an oil-based primer, you can usually wait up to 48 hours before painting.

And if your primer is exposed to too much moisture, it could mildew or corrode. So if you’re not sure how long your particular type of primer has been sitting around, it’s always best to play it safe and use fresh paint.
