My fiberglass door had been painted with what appears to be acrylic latex (?). I lightly sanded, washed with TSP, then wiped down the door with denatured alcohol. I used a very thin coat of Behr interior/exterior latex paint plus primer in a neutral beige, then did a fairly thick coat of Minwax gel stain to top it off. The door looks great, but it has been 12 + hours and the door is still not dry. When I touch it, there are fingerprint marks. Help!
It takes 16-24 hours for gel stain to dry. A very thick application could take longer. The dry time is also dependent on temperature and humidity. Give it time to fully dry before applying a clear finish for protection.
