Zinsser 123 Water Based Primer - Dry Time
I have a project I am doing outside with the 123 Water Based Bulls Eye Primer. We have been having rain off and on and I am trying to get parts of the job completed between the bouts of rain.

On the label it says it takes 7 days to fully cure, does that mean I need to wait that long before it gets rained on?

Please tell me how long after it is applied before rain can come on it. I plan to paint it with latex after it has cured but can't get both done before rain will come again.

The 7 days is the final cure time. You can put your topcoats on after 1 hour as long as it it dry. The topcoats should be exterior rated and dry for the specified time if they are exposed to rain.

Thanks for getting back to me. I understand the topcoat has to be exterior rated and dry the allotted time.

However, I need to know the primer requirements if I can't get to the topcoat due to other obligations. I don't want to put down the primer and lose my efforts when the rain comes a few hours later.

So if I could get a range of time the primer has to dry that would help me to plan accordingly between the rain showers.

In typical ( warm, dry not to heavy application) situations 123 drys to be ready to recoat or get rained on in an hour.
Best to have the rain hold off a little while longer- but the stuff does dry fast. adjust times for humidity/coolness etc.
Top coats are usually at least 4 hrs to be rain safe.

Thanks, that is exactly what I needed to know.
