We are building a pool using shotcrete, and our pool design team has been asked to use the Aquron pool shell protector. The info from Aquron says for best results, spray the CPSP the morning after the shotcrete has been applied. However, our shotcrete company told us to keep the shell damp for a minimum of 7 days. Could you weigh in on this?

The ICC (International Code Council) Building Code requires a 7-day wet cure, which is good practice for concrete or shotcrete. The Aquron Technical Data Sheet mentions prewetting the surface prior to application, but we do not see the direction on the timing. You may want to question the product representative regarding how to accomplish the ICC curing requirements and also get the best results from their product.
