Above-ground Pool Liner Pad - Cushioning and protection: Provides a soft, cushioned pool floor underfoot while helping prevent damage to the liner. It also adds extra protection when placed on grass or concrete. - Anti-puncture protection: Made from premium material, it forms a strong barrier against punctures, tears and abrasion, shielding the liner from damage caused by objects or rough surfaces for long-lasting protection. - Custom fit for above ground pools: Engineered specifically for above ground pools to create a protective barrier that helps prevent metal parts from corroding due to water exposure. For best results, lay down the sand isolation layer, place the liner, and then build the pool over the liner to enhance durability and lifespan. - Easy to use and install: Pre-cut for easy trimming to fit a variety of pool sizes, suitable for both soft-sided and hard-sided above-ground pools, ensuring straightforward installation for all pool types. Use scenarios: - Setting up an above-ground pool on grass or concrete: place the pad first to cushion the floor and protect the liner from rough surfaces. - Replacing an existing liner: install the pad to add a protective layer that reduces wear and prolongs pool life. - New pool installations with a sand base: lay the sand isolation layer, place the liner pad on top, then build the pool over the pad for improved durability.
