We had our pool replastered in late September this year and now it appears to be developing cracks in the surface. They haven't broken through the plaster yet, but they appear as light colored interconnected spider-webbing lines that looks like a road map. The plaster was put on and the pool began filling the same day and finished filling the next day. Has anyone seen this before or know if it will eventually crack through? I haven't called the pool company yet (Jeff Kerber Pools in S. Calif.) as I wanted to get some feedback here first. I've included a couple of pictures showing the problem. The lines don't show up too well in the first photo so I color enhanced it in the second photo to show up better. They're not as hard to see in real life.
In natural light:
Thanks for any help.
