A cautious procedure for reattaching the PVC base of a D-ring, the D-shaped anchor. Continue only when the skin is intact and the ring has no safety role.
Check that the PVC, D-ring base and adhesive are compatible. Follow the adhesive label for amounts, waiting times and preparation.
Prepare the SUP as stated by the board maker and adhesive instructions. Check that the base and PVC are intact. The ring must not be used to support a person, tow or carry another important load.
Continue only when the ring does not support people or important loads and the PVC is sound. If the pressure or purpose of the ring is uncertain, stop and request professional assessment.
Return the base to its original position without stretching it. Check the ring direction and add small marks to recover the position at first contact.
Follow the condition stated by the board maker. Do not copy the pressure used on another inflatable.
Only when the adhesive instructions require it, gently rub both surfaces with fine abrasive paper. Stay inside the outline and remove only the shine.
Do not thin the fabric or expose its weave. If you cannot identify the board or base material, do not sand it.
Remove all dust. Clean the PVC and base separately with the stated product. Test it in a hidden place first and do not touch the clean surfaces again.
Open the cleaner only with suitable ventilation and wait for complete evaporation before applying adhesive.
Spread the number of coats stated on the label over both surfaces. Each layer must be thin and even.
Join only when the adhesive is ready as described on the package. It should not be wet or leave a mark. Avoid thick deposits outside the outline.
When the adhesive is ready, align the marks and lower the base a little at a time without bending the board. Roll from the centre to the edge in several directions.
Expel air and excess adhesive without dragging the part. Do not hide a lifted edge or bubble under another layer of adhesive.
Protect the point from movement, water, sunlight and load for the full time stated on the package. Then inspect the edge and pull the ring only lightly and gradually.
When the adhesive is fully dry, inspect the whole edge and pull the ring only lightly and gradually. Never test it with a person or an important load.
Stop before sanding or gluing if any of these cases applies:
Distinguish a surface bond failure from structural damage, clean the support and hold the EVA under even pressure for the required time.
Check for cracks and use hot, never boiling, water to bring an intact moulded fin gradually back into line.
Seven illustrated procedures, from diagnosis to the condition that says stop.
