I had my very first pool put in, in February. THrilled to death we have been very happy and enjoying it. We had to get a replaster job about 6 weeks after the original plaster job because there was some flaking and othe risses whereby the plaster didnt cure to the gunite very well due to moisture.

In any event, I got a new layer of plaster. Not long after that I began to notice some minor discoloration in the plaster. I talked the pool builder who also says he has a plaster pool and he says even his is like that and thats its normal. Its odd, its only noticeable on cloudy or over cast days, or in the evening when the sun has set. When its sunny or when its night and I have the colored LED lights on, you dont see it.

Has nayone seen these stains or minor discolorations in plaster pools? Im wondering if its some darker color grains of material (I dont even know what all goes into palster) they used in the palster. Thanks in advance.
