Pere Marquette, Flint, Michigan

So I started working on the roundhouse late last week. I began by washing and drying all the parts. I then prepared a mortar wash for the brick face walls. After applying the wash, I noticed something that has never happened before. The wash was not settling into the mortar lines, instead it left a concrete like haze on the brick faces. So, I washed and dried these4 parts again and re-applied the wash, same thing happened. I am stumped as to why this is happening. I think I am going to have to do it with an artist crayon, or a chalk. Has this ever happened to anyone else?
