It will be 3 years in July since moving into this house. There was about a 10ft wide swath of Kool Deck near the steps leading into the pool that was completely delaminated. Our realtor had former experience working for a pool builder and said that kool deck was more susceptible to failure when used with saltwater pools. Can anyone confirm this to be true? Repair of the Kool Deck was part of the purchase and our realtor recommended a company that used some "special" sealant over the concrete that would prevent or greatly increase the time to delamination. The coating applied to the concrete was a viscous white liquid that remained slightly pliable after curing. The edge of decking where it meets the tile was sealed with a black elastomer sealant which has the appearance of silicone or possibly polyurethane. The guy that did the repair said that the in-floor nozzles on the steps were pushing water against the decking and it was getting under the deck and ultimately causing it to delaminate. Seems reasonable to me.
Fast forward to the present. Just shy of 3 years and the decking is coming up in the area repaired. The failure is actually starting at the edge of the slab farthest from the pool. So far, there is only a 2-3" crack on the corner of slab but a larger area surrounding this crack has the distinctive hollow sound.
My questions are:
1-a. Can anyone confirm that Kool Deck is more prone to delaminate when used with saltwater?
1-b. In the case the answer to 1-a is yes, what would be the recommended course of action to use a more suitable decking choice?
2. Is there anything that can be done to repair the delaminated decking? I'm wondering if there is some way to inject some sort of adhesive to prolong the life of what's there... My engineering background tells me it's not at all feasible to even try this, but want to ask just in case.
3. Does 3 years seem like premature for the type of failure described? I'm checking with realtor to see if there is any warranty on this, but doubtful anything will come of it.
Thanks in advance,
BT
