If the surface is peeling or cracking, there are a number of potential solutions. A complete deck replacement is expensive and time-consuming, so it is better to concentrate on repairs. If you find large areas that are cracked or fractured, it will be necessary to fill them in as soon as possible. There are several high-quality caulking agents on the market designed specifically for cool decks, but you should consult with a professional contractor first. If the damage is extensive, another application of the cool deck material should be considered.
