Economical floor padding that protects your liner! New Liner Pad makes old foam floor padding obsolete. Unlike foam, which can be easily cut by grass, roots or rocks under your liner, Liner Pad protects your liner from sharp objects. Liner Pad is tough, but also adds a layer of cushioning. Liner Pad is cut to size and seamed for your pool. No more cutting and taping as with foam. Virtually eliminate vinyl liner bottom leaks with Liner Pad.
