how long to wait for paint to cure?
3 Attachment(s)
I need to paint the edges of an exterior door and the surrounding door jambs, water based latex paint.

How long do I wait for it to be dry enough to close the door?

Is it good enough if its dry to touch? I don't want to close the door then 2 hours later on opening they end up sticking and tearing.

On the other hand I don't want to leave my door open longer than it has to.

Thanks in advance.

There are many variables, temperature and airflow being at the top. Typically, latex dries quickly but below 60f it will slow way down. The best thing to do is a small sample piece in the same environment, it takes the guesswork out of it.

Good paints dry rather quickly but don't cure for 3 or 4 weeks. If you're really in need of shutting the door without a proper dry time of 3 or 4 hours, you can spray some WD-40 on a rag and coat your weatherstripping with the WD thus providing a non-stick surface for the door.

On most doors its pretty easy to just take the weather stripping out. It's the first thing I do when painting an exterior door. Barring rare cases where the weather strips have been nailed or glued in, or older doors that don't have removable stripping, it will just pull right out and push back in.

Doing this allows you to close the door immediately after painting, and its easier to paint the jamb because the strips aren't there to paint around.

A fan will speed dry time.

When painting a door with a rubber weather strip, or where the door and jam will touch, it is most important to use a paint that is non blocking. Non blocking is the technical term for the tendency for 2 latex coatings to stick to them selves, which can occur even after proper curing. Some paints are specifically designed to be non blocking for this reason, and are to be used on doors, windows and cabinets where the 2 surfaces will meet. That is where the advice of a dedicated paint store clerk can help in picking the right paint. If they don't know the answer, they can call their tech line for the advice.
Nonetheless, I also follow all the previous advice just to be sure sometimes. Removing the weather strip will usually allow you to close the door while wet, since it probably does not make contact with the jam otherwise.

Give it between 4-6 hours depending on weather conditions in your area..

It depends on weather also.

In your subject you ask about curing, and in your text you ask about drying. Those are 2 very different things.

Great ideas from gymschu, keith and jmays - I'm going to have to try those out.
