Uneven clearcoat

Hi all,

We just finished putting down a coat of polyaspartic on a flaked floor and it has an uneven appearance.

The customer picked torginols “white cap” hybrid which has mica in it as well.

The flake almost looked uneven or like the white was pooling in one area while the blue was pooling in another, almost like clouds in the floor.

So we scrapped and reflaked the whole floor… same thing

The slab is about 4 months old and has a vapor barrier in place. The highest reading we got on our tramex was 1.5%

The day of install the garage temp was between 47-50 degrees and the material was kept warm up until install

Our system was

Regular cure polyaspartic with full flake broadcast

Scrapped both ways

*reflaked floor due to odd appearance

Scrapped both ways, acetone wiped

Grout coat of regular polyaspartic

Swing machine whole floor to flatten- acetone wiped

Final coat of polyaspartic with flat squeegee, each section was backrolled both directions with no puddles

I want to resolve this but am not sure what the best method is?

I was thinking a HWU in a matte might help even out the appearance
