New chimney done by a contractor about a year and a half ago, now has white on the brick. I think it's leaching from the mortar. Sometimes it's there and sometimes it isn't.

What is up?
Did he use used brick?
I think someone told me once it is lime coming out of the mortar joints. Like I said I notice this happens when you tuck point or pour in cold weather. There used to be two kinds of chemicals you could add to your mortar that would allow your concrete/mortar to be done down to about 20 degrees. One packet you would often get the white bleeding out. The other packet didn't seem to have that effect. The cheap pack was about a buck and the other one was maybe 2 bucks. It is good for an 80 pound bag of premixed mortar/concrete. The good stuff is called Rapid Set.
