Trim & cut it (if needed), and peel & stick the pad to surfboard, skimboard, SUP, skateboard, watercraft or any applications of needing more traction. QUALITY: We only use first grade diamond grooved EVA foam mat, and our tailor-made back adhesive (a special water-resistance layer added between EVA and adhesive) for longer use without peeling off. BUY with CONFIDENCE: All FITACTIC products have been developed and tested. Stored & shipped by Amazon FBA in the US. ***IMPORTANCE: Design the lay-out before pads applied. Strongly recommend marking before sticking.
