I have a failed white pool plaster job being re-done due to delamination caused by a poor bonding agent application. I am interested in upgrading the plaster finish to a pebble-tec type of finish called Crystal Stone Smooth. This finish uses the smaller pebbles. My wife and I fealt it with our hands and feet. I thought it was fine but my wife has concerns that it will tear up hers and our daughters bathing suits. Is this a justified concern? It was smooth to the touch and I couldn't understand how that could snag a suit.
