How long after priming Can I caulk?

What happens if you paint caulk too soon?
“I’ve seen people with a caulk gun in one hand and a paint brush in the other — that’s too soon.” Also, nonlatex paints and caulks that are similar in composition may react to each other, leaving a paint surface that can stay tacky much longer than expected and even discolor, Sicree says.
How do you know if caulk is cured?
Freshly applied silicone caulk has to seal before you use the shower, and moisture in the air speeds the curing time. Even if the silicone no longer feels tacky, it may not be fully cured. If the air is dry, it may take as long three days before the caulk is cured, according to remodeling expert Tim Carter.
Do you caulk before or after primer?
Cracks show up better after priming, and caulk adheres better to primed wood, so complete any priming before you caulk. For a neat job, caulk all joints. Caulk all the joints between trim and wall surfaces to prevent penetration of moisture vapor into walls.
Can you leave caulk unpainted?
Most types of regular paintable caulking will discolor if left unpainted. There are some tub and tile caulks, modified silicones, and custom color caulks (caulks with paint added) that can be ok left unpainted but I wouldn’t think the dynaflex falls into any of those categories.
