We recently had our 20x40 inground pool replastered. A few weeks after the replastering, I noticed hairline cracks around the upper part of the walls and the steps. We talked to our installation person (who basically contracted out this job to someone else) and he said that our Ph was too high and it was our problem.
We do live in an area with a high water table, they did remove all of water to replaster, and the pool was refilled with our garden hoses, which took a few days.
Did the upper portions of the plaster "cure" too quickly and now are cracking? What does the Ph of the water do to new plaster?
Any information or pointers to information will be greatly appreciated. Thanks.
