A procedure for reattaching an edge of the deck pad, the non-slip mat made from EVA foam. Continue only when the mat has lifted and the SUP skin is intact.
Confirm that the product states compatibility with the EVA foam and the skin beneath it. Do not replace the manufacturer's instructions with generic timing.
Bring the board to the minimum pressure stated by its maker that keeps the area firm. Lift only the edge that is already detached. Check that the EVA foam has lifted, not the board skin or a seam.
If air escapes, the support separates in layers, a bubble or soft area appears, or the EVA is friable and torn, stop: this procedure is not suitable.
Place the SUP at its specified working pressure on a surface that supports the entire area without creases. Remove sand and moisture, then prepare ventilation, tools and weight before opening the adhesive.
The flap must return to position without tension. Do not bond outdoors when wind, sunlight or humidity prevents compliance with the product instructions.
Gently remove only old adhesive that is flaking away. Clean the EVA and support using the compatible method specified by the manufacturer, then mask the outer edge.
Test a hidden area first: aggressive solvents can attack foam, print or PVC. Allow everything to dry fully and do not contaminate the surfaces.
Return the flap slowly to its position and check that grooves, edges and graphics align. Plan to lay it from the still-attached area outwards without trapping air.
If the pad has shrunk, changed shape or no longer covers its original area, replacement may be more reliable than gluing it back.
Spread the adhesive in the amount and on the surfaces stated on its label. Wait for the time printed on the package before joining the parts.
Do not saturate the EVA or leave deposits that could escape onto the standing surface. Close the container immediately and maintain the specified ventilation.
Lower the flap from the still-attached area towards its edge and roll in several directions to push out air. Add a clean protective sheet, a flat board and an evenly distributed weight without changing the SUP shape.
Maintain pressure for the time specified by the product. The weight must act on the repaired edge without creating a crease or compressing a nearby valve.
Do not deflate, bend, wet or use the SUP until the full time stated on the package has passed.
Remove the weight, inspect the whole edge and test it only lightly. Soft areas, bubbles or renewed lifting require a fresh diagnosis.
Stop before applying solvent or adhesive if any of these cases applies:
Check for cracks and use hot, never boiling, water to bring an intact moulded fin gradually back into line.
Identify the system, retain the base plate where required and replace the box without guessing compatibility or timing.
