PVC Zodiac Inflatable dinghy Restoration.
The process taken to Refit the Transom back on to the PVC tubes.
6. Rowlock after cleaning. This is first primed with Hypalon single part adhesive because the fitting is made of rubber.
A/. PVC Adhesive does not stick to Rubber
B/. PVC Adhesive will stick to Hypalon Adhesive
8. The Polymarine Single part Hypalon adhesive and cut down brush ready for priming the cleaned up wood with hypalon adhesive so that the PVC adhesive will stick to it.
A/. PVC Adhesive does not stick to wood.
B/. Hypalon Adhesive will stick to wood.
C/. PVC Adhesive will stick to Hypalon Adhesive.
The sanded wood was primed with a thin layer of hypalon adhesive and allowed to dry. In this case, the wood had absorbed a lot of the hypalon adhesive, so a second thin coat was needed and allowed to dry for 1 x hour.
9. After Hypalon Adhesive priming the application of Polymarine 2 part PVC Adhesive for final gluing.
The Primed wood had a thin layer of PVC adhesive applied and allowed to dry for 1 hour. The transom was then ready for gluing to the PVC fabric and components
The PVC side fittings (not the transom) were first primed with 2903 Solvent and Primer For PVC Fabrics in preparation to receive the PVC adhesive. The solvent primer was rubbed onto the side fitting surface, and repeated a number of times until they felt sticky/slimey to touch. At this point the first layer of glue is applied to the side fittings.
When both PVC side fittings and the Transom surfaces had dried for an hour (or more ) a second thin coat of PVC adhesive was applied to the Transom and side fittings and after about 5 mins, whilst still tacky brought to together for bonding, applying as much pressure as possible to remove any air bubbles. Note, If the surface of glue had dried before sticking together, the glue could have been reactivated by wiping lightly with the 2903 solvent primer.
Similar to the previous process, the PVC fabric was first primed with ‘2903 Solvent and Primer For PVC Fabrics‘ until it felt sticky/slimey to touch. At this point the first layer of PVC glue is applied to the fabric.
When both PVC fabric and the Transom surfaces had dried for an hour (or more ) the second thin coat of PVC adhesive was applied to each surface.
The surfaces were brought together after about 5 mins whilst still tacky. Rubbing down and outwards with a smoother tool. Then checked that all the edges are stuck down and no air was trapped between the surfaces. Excess adhesive was rubbed off to create a clean finish.
Note: If the adhesive had flashed off and was not sticking correctly, then gently warming the area with a hair drier or a hot air gun and a push down with a smoother would be an effective remedy.
The Zodiac was left to dry overnight. (Note: it should be at least six hours before putting pressure the transom and floor) A Full cure was reached in 48 hours, and a Maximum Bond Strength by 7 days.
