Repainted front door - it's NOT drying

So we decided to re-paint the peeling and cracking front door.... trying to do it right, I removed it and set it up in the drive way.

I sanded the door (both sides) with 60 grit sandpaper, covered up the glass, and got to it.

I used an airless sprayer and sprayed Zinsser Exterior/Interior primer, let it dry, flipped the door, and did it again.

So the next day (which was yesterday) it was time to paint. I sanded the door with 150 grit sandpaper, (both sides) and then sprayed the door with the Glidden Ultra Hide Oil based Semi-Gloss. It was really windy yesterday so I had to move operations into the garage. That painting was done at 4:15 PM yesterday, and as of this morning at 9:30, it is still very sticky.

I was going to sand it again and then do another coat, but I can't since the door is so sticky. I'm not sure what to do here. I live near San Antonio so it's not real cold and I even left a heater running in the garage overnight in the hopes that would help it dry.

Does anyone have any advice on how I can get this door finished? I really need to get a door up on the house. Thanks for any help.

 

Cool and damp conditions will slow down the drying process, especially oil base paints. An airless puts out a fair amount of paint so you've likely got a thick coating on the door which will also slow down the drying.

Is this a metal or wood door? With 1 coat primer, 1 coat finished, both coats sprayed - the door should be done, just needs to dry. A wood door needs to have at least 1 coat brushed [or sprayed/backbrushed] to help work the coating into the wood.

Adding more heat will help speed up the drying but basically it just takes time.
