The only time I've ever seen anything similar, and it was nowehere near as bad as yours, we figured out that the flags had not been pre-wetted, and then the Rompox hadn't been properly washed off the surface while still 'fresh' but had been left for 3-4 hours or longer to "set", according to the neighbour that witnessed all this, which is not what's written in the installation guidance.
I am NOT saying this is what has happened on your project, but, in an effort to help you, I need to check:
1 - did you thouroughly pre-wet the surface before applying the Rompox?
2 - did you leave the Rompox on the surface for no longer than 20-30 minutes?
3 - did you wash off the surplus, rather than just sweep off, or let it dry then brush-off?
