Thanks I'll heed that advice. Unfortunately, I did apply that to some (small) areas already. Should have consulted you guys first.
What I do notice is that where the water repellent was applied, the water beads on the surface of the wall rather than being soaked into it. That does seem to depend on the texture of the wall, which for the most part melds well with the repellent making it feel and behave like a glossy paint.
So in that sense, how does it prevent stucco from drying out? Or do I assume some portion is still absorbed into wall while the other is not staying outside as water beads? Can someone clarify the bad behavior of water repellent on external wall?
Also, what about some patched areas of wall, patched with concrete and where the paint is chipping off wall, how best to protect those areas? I'm not sure what the original type of paint was used, and don't want to strip the paint off the whole wall and repaint just for where the chips are. It appears the original paint was really a thick base based on the peeled off hard thick paint layer I got where it was chipping. Or it's a layer of paint mixed with something else. I'm new to painting and have never noticed dried paint that's as thick/hard as a Ruffle's potato chip (or say thick flat potato chip).
