hydrazzo

We just passed final inspection and all we have left is picking a finish. My husband and I both don’t like the feel of mini pebble from NPT but got a quote for 8k and they will grind it down, hydrazzo at 13k and Primera stone at 17k, and polished scapes at 20k. I really wanted Primera stone but...

Can hydrazzo be put on uniwall? I have a 15 year old concrete bottom with uniwall(fiberglass) sides that needs to be replastered. I would like to do both the bottom and sides with hydrazzo. I have a local contractor that says he can do it. Anyone out there have experience with this?
