Six years ago I paid 14 thousand dollars to have my pool replastered with Gunite sprayed. He hardly put any plaster on the walls. It is very thin. You can see right through it. For years I begged him to come and see what a horrible job it is. Now the walls are cracking and pieces broke off. They were supose to fix the cracks before plastering. The first time we did it 25 years ago it lasted for twenty years. I had a pool company open the pool that knew him and he told me that this would happen
