So our pool company when finishing the pool last year just put this spongy Styrofoam like material between the cement and the coping and said we're 'good to go'. Now we are hearing that if we don't replace that with caulk then water gets in, freezes, and ruins the coping over time.
Question 1- is that true? can we just leave that stuff in or should we caulk?
Question 2- What product should we use. We get 100 different answers on what to use, what is best, etc. We want to do it ourselves as it is very expensive to have a contractor do it. Any experience with Vulkem products? Ultimate Pool Sealant? General advice?
Help me TFP...you're my only hope.
