I like it when our supervisors ask me to explain my instructions, though I
often have to admit it is a plan based on the benign ignorance of experience.

I've always been told not to use latex additives in brick mortar but I do not
know why. I realize that latex additives are used in new construction, but I
never do new construction. I know enough to never suggest using a latex
additive and let the design professional make the first move. But the whole
thing is a mystery to me.

Could someone please explain the pro/con of the latex additive taboo?
