Well after almost two years our pool was plastered yesterday and everything went wrong from the beginning! I told them to send their best crew, when they got here I said I'm just confirming that this is a two day process, I was told by 4 people that you acid wash, plaster and then the next day acid wash to expose aggregate and start filling si I had the water truck set for the next day, well they barely spoke english, he said no we do it all in one day, I said that's not what I was told don't you need time for it to cure? I quickly called a rep. from cli industries who makes the product sunstone pearl black pearl pebble finish. They said it's okay for one day as long as u give it some time to cure, because waiting too long can cause cracks, so I went with it. Next dilemma was, I showed them the 11 feet long hairline crack on the bottom of the pool and said I was told by my engineer and others to just put alittle hydrolic cement over it that it was a normal shrinkage surface crack only. I told them not to cut into it, as sometimes they do for larger cracks, I turned my back for 1 min. and heard the drill they cut into it about 1/4 inch!!!!! I flipped out on them, they said this is how they normally fix cracks cutting into it 1/4 inch and filling with hydrolic cement, i called the guy from cli industries and scott from the forum they calmed me down and said that is typically okay trying to strengthen the crack, howevere I told them to leave it, I'm worried it was so tiny before and now they made it so much wider!!!! I will obsess over it now waiting for it to crack! I hope not! Anyway the next thing was they brought gray drains had to search for black ones and realized that they didn't have black rope cup holders, left to get some, guys waited around for 2 1/2 hours for him to return, drilled into my pool wall to remove the white ones, and then the rest of the project got rushes so now I have extreme mottling/variations on bottom of pool, please tell me with brushing this will come out and it is normal, I think so?? Any advise would be greatly appreciated, what a rough day, glad it is all over!1 Michelle
