Answer for Using Kilz Original Primer Outside?

Original Kilz dries hard with little flexibility and isn't good for exterior use. I would use it for spot priming only with an exterior application and not do large areas like the entire side of a house.

You will have no problems with the paint adhering and as a spot primer the surface would be protected. The only problems is using it over large areas; it doesn't have the flexibility and temperature tolerances needed for a good exterior primer.
