TIL my whole plan for a stucco patch job was wrong

Honestly, I tried to fix a crack in my stucco near the UNM area last weekend with some premix stuff from the hardware store, but it all just crumbled out after two days. Ngl, a neighbor came over and said I didn't wet the wall down first or use the right base coat, which makes total sense now. What's the right way to prep the area for a small repair like that?

Ever feel like you're the reason they put warning labels on things? I've been there. I once tried to patch a hole without cleaning out the loose stuff first, just slapped new mud over old dust. It fell out faster than I could put my tools away. For a small crack, you gotta chip out any loose bits until you hit solid edges, then soak the area with a spray bottle for a good while. The old stucco will suck up water like a sponge, so keep it wet, then apply a bonding agent or a scratch coat before your finish coat.

My last patch job failed for the exact same reason.

Weren't you supposed to wait for the bonding agent to dry first before the finish coat?
