Made from dense, tear-resistant felt with hot-stamped finishing, the pad is pre-cut to fit 18 x 9 ft rectangular pools but can be trimmed for other sizes. It works on common surfaces such as grass, gravel, and wood decking, and installs quickly without adhesives or complex tools.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pad protect my pool liner?\u003c\/h3\u003e\n\u003cp\u003eThe pad adds a physical buffer that prevents sharp stones, roots and rough ground from puncturing the pool liner.
