Not sure if this is best forum for exterior walls, but starting here.
I believe exterior wall is stucco w/ layer of paint over it? There's a few parts of wall where there was opening before and was patched w/ what is concret mix?
And one section had the paint peel off.
I don't have the original paint color nor type of paint info. Finding a best match paint might not match perfectly.
From the photo you can see I applied waterproofing sealant in the area, and that was before I found out from another post I made here that I shouldn't have done that. Should have checked before applying. That sealant was general sealant for wood, concrete, and stucco, and has ethylene glycol in it (need to check for other ingredients). I also caulked the crack lines, and edges where pain peeled off.
What is and/or should have been the proper fix for this? Though I'd rather not have to strip the whole wall of the original paint and repaint the whole wall, nor to have to break up the concrete hole patches and repatch the right way, if the concrete patch job is bad. But in any case, seeking advice.
I would scrape off all the loose paint and cover the cracks with a heavy mesh tape, and then coat that whole area. Use a sponge and water and get the edges wet and tamp them until the edges are as good as you can get them to perfect. the aggregate cant be replicated
