Repair PVC Dinghy and Valve Change - Zodiac Dinghy

A detailed guide of how to make a repair to a PVC inflatable boat or RIB collar.

Right tools for the job

When repairing your inflatable it's vital that you use the correct adhesive, solvent & work in the right environment, so make sure the area is well ventilated, dry (less than 60% humidity), and between 18-25 degrees C.
Due to the flammable nature of the adhesives, do not use them near an open flame. Using the incorrect materials & working in the wrong environment will often result in unsuccessful repairs.

Is my inflatable boat PVC, Hypalon or PU?

Finding the leak

If your inflatable tubes are losing air pressure, use soapy water to identify the problem areas.
A common cause for loss of air pressure is your inflation valves, so check these first.
Use 1 part washing up liquid to 20 parts water in a jug and use a paint brush to apply.
After checking the valves, look for any visible scratches or worn areas on your boat and bubble test them.
If you still can't locate the leak, you will need to brush over the whole inflatable.

Mixing the adhesive

2-part adhesives are for permanent fixes (whereas temporary fixes can be obtained with 1-part adhesives). It is important that you mix the curing agent and the adhesive in the ratio specified by the manufacturer.


For larger repairs

Punctures with a tear or hole less than 20mm can be repaired with an external patch. If your tear is larger, you will need to patch it internally as well as shown.
