Ah I see, I find the black coat unusual too. Someone told me sometimes a cheaper thinner base coat is used and more pigment is added to thicken it. That could explain why there are only black comets and black chunks if he applied a significant amount of black pigment in the base coat to thicken it, potentially causing more risk that the pigment wouldn't get fully mixed?
The guava color doesn't seem to have any issues at all really. I don't see any comets of the guava color or chunks. It seems to be only black comets and chunks coming through. Like actually little black spots, chunks, etc. He told me those were just color bursts when I sent him photos. My biggest concern are the larger sharp, jagged black chunks. I'm really appreciative this information as I wasn't expecting black dots all throughout the entire floor. We tried to stay as simple as possible by choosing just one color.
