A cautious procedure for checking an opened side seam, closing it and protecting it. Stop if the internal threads that hold the SUP in shape are cut or distorted.
Use a two-part adhesive stated to be compatible with the board’s PVC. Amounts, waiting times and use of heat must follow the label on the adhesive you actually have.
Fully deflate the SUP and inspect the whole opened seam. Check whether only the side skin has lifted or whether the internal threads or pressure-holding fabric are cut. Inspect both ends of the opening as well.
Continue only if the threads and fabric that give the board its shape are intact and the edge returns to its original position without force. Otherwise, request a professional assessment.
Place the deflated board on a clean, dry and well-ventilated surface. Read the adhesive label, remove flames and sparks and cover nearby graphics before opening the solvent.
Work only when temperature, humidity and wind allow you to follow the adhesive instructions.
Carefully remove only old adhesive that is loose and unstable. Use a lint-free cloth to apply the approved preparer or MEK to both faces of the joint while avoiding printed graphics, then wait for the solvent to evaporate completely.
Test it on a hidden area first. Surfaces must be dry, clean and even; do not sand or thin products by habit when the manufacturer does not require it.
Measure the two liquids in the amounts stated on the label. Prepare only what you will use and mix until the mixture is even.
Use the mixture within the time stated on the package. Do not copy amounts or timing from another adhesive.
Use a short brush to spread a thin, continuous layer over both faces. Cover the corners without leaving thick deposits.
Wait for the time stated on the label before adding another coat.
If the instructions require it, spread a second thin, even coat. Cover the corners without creating lumps.
Join the parts only when the adhesive is in the state described on the package. Do not shorten the wait.
Close and remove solvents, containers and cloths. Let plenty of fresh air through the area. Only when the label requires it, warm both surfaces while keeping the tool moving. Return the rail to its original shape and join the seam a little at a time.
Do not guess a temperature. Press from the centre outwards to remove air and excess adhesive.
Cut a compatible PVC strip long enough to extend well beyond both ends of the opening. Round the ends. Prepare it as stated on the adhesive and place it without stretching.
Carefully press the step over the old seam and then the whole strip from its centre towards the edges. Do not hide bubbles, creases or lifted ends: correct them before the adhesive dries.
Protect the repair from movement, water, sunlight and heat. Wait for the full time stated on the package before inflating or using the SUP.
Inflate gradually in the shade to the SUP manufacturer's prescribed pressure, check the seam with soapy water and monitor pressure. In future, do not leave the board highly inflated in the sun: reduce pressure when necessary while remaining within the manufacturer's operating limits.
Stop before using solvent, heat or pressure if any of these cases applies:
Check the D-ring base, the skin beneath it and what the ring is used for. Bond only materials stated to be compatible.
Distinguish a surface bond failure from structural damage, clean the support and hold the EVA under even pressure for the required time.
