Just purchased a house (first time homeowner) and I'm realizing there is of course a lot I don't know about it. I'm trying to hang a mailbox on what I think is a stucco wall, but apparently there are many different types (and some of the potential fasteners I'm considering say to only use them for certain types of stucco (like synthetic, mortar, and some others - Portland?).
Our home inspection simply says "stucco" and the wall is very smooth and a white/light gray color.
How can I tell what kind of stucco it is (assuming it is stucco) and if whatever anchors/screws I'm looking at are appropriate?
