I think you covered about every possible reason why something like this
happened and you’re not going to get an argument from me about either one
of them. Thanks for taking the time to leave the comment. We see things
every day that don’t make a lot of sense, until we actually find out the
reason why and this is a good example of one of those things.
The biggest cosmetic difference here is the different surface texture in
the patch compared to old. The stones are right on the surface rather than
settled as in the finished older work. I suspect it dried too quickly and
they didn’t trowel it enough to allow the stones to settle below the
surface. Or, maybe it rained and the top was washed away. When you buy
readymix in bags you should buy extra Portland cement to give better
durability for the topcoat smooth surface.
