Most products require at least 4 hours of dry time before moisture can settle on the surface. The cooler the temperature the sooner you should stop painting.
Even if a surface does not appear to be wet, it might have latent moisture that could affect your paint. An exterior wall that was rained on may require four hours of drying time in direct sunlight and temperatures at or above 72 degrees Fahrenheit to be fully dry for painting. Ideally, you would want to wait a full day for the surface to dry.

Frequently Asked Questions
How long should outdoor paint dry before rain?
If you are using latex paint, you need a minimum of two hours of direct sunlight before the rain comes. Paint may feel dry to the touch after an hour but it will still wash away. After two hours, light rain will not completely ruin your work but you may still have to repaint some of it when it is dry.
What temperature can you paint outside of house?
“It should be at least 50° F when you're applying the paint and shouldn't drop below 32° F at night for several days after,” says Rico de Paz, who oversees Consumer Reports' paint tests.

How long does it take for wet paint to cure?
By the next day, you don’t have to worry about bumping into a wall and getting covered in wet paint. This is helpful because it allows you to get back to your normal routine – and appreciating your newly painted home – faster than ever! Although exterior paint dries in a few hours, it can take up to 30 days to fully cure.
When is it safe to paint in wet weather?
If this happens, the best solution is to wait till weather clears then repaint. High humidity, dark colorants, cool temperatures and reaching the dew point all slow up the drying time. Wind and warm temperatures speed up the drying time. Heat and air movement are critical for the paint to dry. The dew point will affect the drying time the most.
