We recently had 30sqm of "brushed grey concrete" poured down the side of our house.
Upon further inspection a few days after it had dried, it has "spots" all over it. Like maybe started raining slightly after it was poured. It looks a little unsightly from a cosmetic point of view.
Also, there are about 2 small chunks that have come up from the concrete. Not big chunks, about 3 cm diamater crator left in the concrete.
Also when looking from one end to the other of the concrete, it doesn't look flat and smooth, but rather every so slightly raised, then not so raised.
Do you think this sounds like quality in your opinion and should we complain before handing over payment?
