What Each Finish Actually Hides
A flake blend is the most forgiving of the three. The chips break up the plane visually, so dust, a dropped tool mark or the ordinary traffic of a busy house does not read as damage. It also gives the floor texture underfoot, which matters anywhere things are likely to be wet. If you want a floor you can stop thinking about, this is usually where you land, and it is the finish that goes down most often.
A metallic floor does the opposite: it is there to be looked at, and it shows what happens on it. The pour creates depth and movement that a flake floor cannot imitate, and in a room that is on display that is the whole point. A solid color sits between the two and is the cleanest looking of the three when it is new, though it is also the one that will show a scuff soonest. Which you want depends on how the room is used and on how much you want the floor noticed. Whichever finish you pick, the system under it is the same: here is how the base, color and topcoats fit together.
