I am trying to get info on our new pool plaster choice-We were originally going with a different company that was offering something called Polished Pebble (Hobert) but our final choice was a company that promised a comparable product-They said that Stonescapes Mini-Pebble was the name of a finish that was smooth but after researching I found that this is more of a 'creek bottom' feel and has a roughness to it..opposite of what we wanted-We were looking on NPT and found Polishedscapes as the product that seems to be comparable to our original choice- Our pool contractor is stating this is much more $$ and that they are having trouble finding anyone who 'polishes' the plaster install. I wanted input on this from someone who may know about this process-I am definitely not going with the minipebble style. Is it true that the polished aggregates are more difficult to install? Thanks so much.
