Olympic 391 G 1 gal Blue Ice Zeron Epoxy One-Coat is the longest lasting epoxy pool coating available. You can expect up to eight years of service from one application of this product. The greatest advantage of the Zeron system is that it only requires one coat. Zeron is a heavier bodied material than Poxolon 2 so it will require a little more effort in its application and will not spread as far. However, due to the extremely long life of Zeron, the cost per year of service is lower than any other pool coating available.
