Since TC is usually glazed the no-no of coating on masonry is a somewhat 
moot point as it already has a coating. As to if it is good bad or 
indifferent to coat TC there is a discussion amidst the conservation 
technicians moreso than the trades. The discussion will likely last an 
indefinite number of decades and never be resolved as much as ppl worn 
out on it and fresh troops needed. I do suspect a problem tho w/ the 
wholesale coating of the mortar joints.
