redoing the job?
Tear it off. I would stand toe-to-toe with them. We do work that is less than perfect, too, but I feel they should tear all the mortar down to the lath and do it over. Our base coat is so hard that you can’t shoot a bullet through it. It should have a compression strength of >2000psi, like concrete. Also, experienced people should put it on, not the same people. There are a number of reasons that this happened. First they didn’t use portland but probably masonry cement. Probably type N, which is real weak. Second, they probably put way too much sand in the mortar. Third, they probably retemper the mortar after it set. If you can crumble the mortar with your bare hands, probably all of the above. Another thing , if the wall is the hot sun, mortar tends to dry out before it sets and turn to powder. The solution is to constantly keep the wall wet while you are working. We don’t do any damp curing because I don’t have time. If it is real hot outside it doesn’t really do much good. I don’t
