We had our pool replastered in January and the mottling is throughout the pool (walls and sides). We kept thinking it would fade as the plaster cured but it has not. The plasterer said he would come over Monday and take a look. He said it was probably the start up (the guy who did the start up was erratic at best but I didn't tell the plasterer that). Anyway, the plasterer said we may be able to drain the pool and do a light acid wash. My questions are:
*I live in the desert and we are averaging high 80's and low 90's at the moment. How long can the plaster safely be exposed? I'm assuming the whole process could be completed in a few days from drain, acid wash to refill.
*I've read that you may not need to drain the pool for an acid wash but I'm assuming doing it the way the plasterer suggests is better. Opinions on types of acid washes?
*After refilling the pool do we need to wait on adding salt, etc? Or just start balancing the water immediately?
*Anybody have this same situation and did the acid wash really help? If it's not really going to help I'm thinking of seeing if he will give me a credit instead of going through the hassle of this if it's not going to look any better. We are also in a drought so I feel guilty about draining the pool twice in the last several months.
When the sun is shining on the pool you don't notice the mottling and it looks sparkling and wonderful but when there are shadows and the water is still you can clearly see it throughout. I know mottling is inherent in plaster but mine doesn't look like fresh plaster, it looks much older. I've gone to a few open houses with freshly plastered pools and I can see the difference.
