This Blue Wave liner pad arrives ready to place—no cutting, trimming, or guesswork—so you get consistent coverage across the entire pool floor. Built from white serged-edge felt, it’s designed as a protective barrier rather than a heavy cushion, making it a practical and low-maintenance choice to extend the life of your liner.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pad protect my liner during installation?\u003c\/h3\u003e\n\u003cp\u003eThe pad creates a continuous buffer between the ground and the vinyl, reducing the chance of sharp objects puncturing the liner during setup and use.
