Does anyone have experience deciding between Jahn mortar and traditional stucco?
We are replacing 80+% of the stucco on our brownstone co-op's facade, some 50+ years since it was last replaced. The contractor suggests traditional stucco will suffice, while the engineering firm is pushing Jahn mortar, despite the significantly higher price.
Any thoughts appreciated ... particularly if you have a view on whether traditional stucco, well applied is sufficient. It would be great to save some $$ ...
We worked closely with Landmarks on a restoration in the Upper West Side and selected Jahn as the product manufacturer for both the brownstoning and the masonry grout. I was pleased with Jahn's product information in their specs, and LPC was happy to see a product they were familiar with be used. Also from discussions with the Brownstone contractor they were comfortable working with the Jahn product.

To answer my own question, for the benefit of others: Jahn is vastly more expensive than stucco and likely unnecessary. It is a better product, technically, but not worth the additional expense, IMHO. Rather, if one applies stucco correctly and conducts proper inspection and maintenance, stucco should last fine.
