I’m thinking bad surface prep and that it was re-finish coated at some point. 1920s build, hard coat. What ya’ll think on a fix or cause etc. of this. Only photo I have, this photo was sent to me.
Sorry Brandon, I report defects not prescribe fixes. Plus, I’m not that familiar with stucco (If it is for a friend.)…being from the north.
What did the report say?
Right, i don’t report fixes either. I do appreciate your response as always Larry, if I can count on anyone, its you in these forums. But yeah this is for a friend, and she sent me this pictures. I usually I report on cracks, etc. being relatively familiar with stucco in this area of Minnesota I sometimes, offer possible causes, although I disclaim of course its not my job to determine these, they’re just suspected causes. However I have seen this a few times and my guess is improper prep work on the finish coat of hardcoat stucco and was hoping someone had some input to either confirm or otherwise this as well as options moving forward.
Definitely delaminating. I can see a loose piece upper left that has “loss of adhesion”. Once water starts getting behind the coating, spalling will finish the job. As far as a cure…mechanically removing anything that does not have a bond is a necessity. From there it is a patch job. Getting it to match will take some talent.
Just curious, does the home experience freezing temps?
I completely agree. Moisture intrusion destroys stucco.
Wow! I’d like to see that matching…course, I don’t see much except attempts at parge coat matching up here.
Yes it does. 100+ humid summers, and -10 winters. Plus we get a decent amount of rain. Not an ideal climate for stucco in my opinion, but people love it for some reason.
Once she has a competent stucco inspector (not repair contractor) out to inspect it, etc she will have a good idea of whats going on and what kind of repairs are recommended
often the result of inclement weather application & brown coat (bc) curing/prep before acrylic finish coat (fc) is applied & properly “dried”
subsequent moisture-freeze-thaw provides the end result
they should remove all damaged surfaces down to bc, prep & apply a new fc hopefully with better bonding & weather resistive properties
that heavy dash texture can only exacerbate moisture absorption/entrapment
