This material has been installed over a cinderblock structure. Sounds thin and hollow, looks thin. Halfway down the chimney, the cladding has blistered. and is popping loose. Also missing kickouts at RTW intersections. If nothing else, sub standard install. What type of material is it?

The mesh might point to EIFS or Polymer Modified hardcoat. If it's EIFS then you should be able to push on it with your thumb and see it move as you compress the foam behind it. If not it's PM. I'm leaning towards PM because of the way it's blistering on the chimney... The moisture is coming through from the flu and messin with it. It's a crap ass job either way.

Well it is a typical EIFS mess, but on CMU? The chimney has been patched or repaired in some shape or form. Based on the texture I would say that it is a PM type EIFS system. Really makes little difference at this point. It should be removed and properly reapplied to cover the CMU.
