This quart of Clear Pond Armor is a nontoxic two part epoxy sealer designed specifically for sealing concrete, steel, wood, fiberglass, etc. with a thick, durable coating. Easy To apply - No special equipment needed, just brush or roll on! Flexible - Pond Armor remains flexible from -78 degrees to 140 degrees Fahrenheit. Durable - Unlike other sealers, Pond Armor bonds to the substrate rather than just covering it. This leads to longer life with less repairs and maintenance. Beautiful - Provides a smooth, hard finish with no wrinkles or folds. Also makes surface easier to clean in the future. Covers approx. 60 square feet of surface area. Will need to clean substrate very well before application.
