What’s the maximum and minimum temperatures to paint stucco.

OK, its going to be 50 degrees for the next four days, then some rain-maybe. Trim has been sanded down to bare wood (90%). I need to prime, latex or oil? Thinned or not to thin?? Night time temps will hit 30-35. What type of Primer? Latex going on top

How much water should I add to a full gallon? Thanks
