If your wetsuit has suffered a puncture, remember that little holes tend to become big holes, so repair it immediately and check regularly for tears.
A small nick, which will probably look more like a crack than an actual hole in the material, can be repaired using wetsuit cement or glue. First, fold the suit at the point of the cut, forcing it open. Apply a thin layer of the glue to both surfaces. Give the glue a couple of minutes to dry and then press the two sides together. It’s best to then leave the suit unused for at least 5-6 hours to ensure the bond has time to set. The glue is flexible so it will stretch with your suit.
For larger holes, you will need to use neoprene patches. Clean the area and stick the patch over the hole. Alternatively, sew the hole as you would any other garment. This is tough work, and some people recommend dental floss as a hardwearing thread. Use wetsuit sealant over the stitches to ensure no water gets in. Leave it to dry overnight and you’re ready to return to the water.
Fold the wetsuit over to open the cut and ensure both surfaces are clean.
Apply an even coating of glue to both sides and then hold open for 2-3 minutes.
Hold the sides of the tear together. Apply light pressure to allow the glue to bond.
Lay the suit flat and leave to fully dry for 5-6 hours, or overnight if possible.
