I just finished installing a new fiberglass pool (about 2 months ago). I had a very large concrete slab poured around it. The contractor sealed the concrete and for about the first week the water beaded up and the finish was brilliant and glossy.
Fast forward a few weeks and the water on the concrete no longer beads up and there is a white residue over it that is destroying the look that I wanted to achieve with my concrete.
The levels in the pool are good. It was a little up and down at the start (ie: chlorine levels very low; ph really high; low to non-existent CYA). All of that is now in a very good range. The only exception to that is the CH (tested today at 400 ppm). We naturally have hard water here in Burbank, CA. So that accounts for why the CH is on the higher side. It is our belief that this hard water is the cause of our dulled finish on the concrete.
Has anyone else had an experience like this? What do you recommend doing in order to get our concrete looking like the $9K that we spent on it (stamped and colored)?!
