We have a new gunite pool with grey plaster. It has been about 3 weeks since it was done, and the plaster has very tiny white hairline cracks everywhere in the grey plaster. It looks like when you crack an eggshell. I was told that this is a normal thing that happens when plaster dries, and that it is just more noticable in a darker colored pool. The horizontal surfaces, like the steps are where it is the most noticable. Is this true, and should we just enjoy it as part of a natural substance (plaster)? Does this eventually become less obvious? Our friends have a white pool and you can't see these lines. In our pool, there is no area where there are any large cracks, just these tiny spidery ones.

My first inclination was to tell you that yes, Crazing cracks do appear in plaster. However a searh turned up these sites that will answer you questions. In short, yes it is normal and should become less noticible. ( I assume the pool is full!)
