I have recently acquired a 1999 Zodiac Pro 470. - my first RIB
I have a beginner's question regarding tube repair.
The tube had a slow leak which I have traced to repair patch which was coming off and needs to be redone. I removed the patch and the hole is very small (2mm).
I cleaned the area (old glue) completely with MEK.
I think that I have established that my tubes are PVC because: 1. I noticed that the red colour smudges onto my cleaning rag, and 2. When I look inside the tube, through the valve, it is the same red colour.
I have the special PVC glue, I am waiting for the right humidity, and I know that I am supposed to apply the glue to the tube and patch, wait 3-5min, reapply some more glue etc... but when it comes to actually putting the patch onto the tube, how do I do that? do I deflate the tubes totally when doing the repair? Do I have to remove them?
The boat is on a trailer and has a 50hp outboard on it, so do I deflate the tubes totally and then press the patch against the tube which is in turn pressing against the hull? or do I leave the tube slightly inflated?
I have one of those little screen door spline roller thingies (http://goo.gl/FKES1
) to get any air bubbles out, but do I need to then push my hand firmly against the patch for a while (how long)?
