toob repair

bingosucks · 22 April 2013, 19:19

toob repair,i inflated my shiny red second hand excell and had a slightly deflated feel

on closer inspection a couple of patches had been done i swabbed with bubbles eureka !

tonight i have used a heat gun and removed the offending patches one was covering a 50p sized hole, which i`m guessing is going to take an inside and outside repair

the toob is red inside too indicating a pvc boat, now i`m guessing the repairs failed due to impatience and failure to clean and key the area

there are plenty of threads with advice on the forum but would love to hear `direct` and what glue to use

Well to begin with, whatever method you use to glue and patch, get everything superclean and then cut a fill patch to fill the 50p hole you have. Get it to fit as closely as possible even if it means trimming the existing hole. That way the patch will not sag.
What you may need to do is open up the hole a bit more in order to effectively apply an inner patch, onto which you will apply the filler patch, you should then have a decent and even surface for the final patch to adhere to.
Don't be concerned by going "big" with the patch.

thanks for that mister p , would you leave it 48 hours to apply the outer patch too ? and i didn`t think about the filler patch ,makes absolute sense again would you leave that to cure or just a couple of hours

wondering too what glue to use , cheers rich

mister p · 22 April 2013, 20:15

If you let it cure you can trim it smooth and then work the top patch onto it properly. Don't rush it and it will look great.

There is two part PVC glue generally available from chandlers if you are positive that it is PVC.

cheers wilk ! i will even out and widen slightly the gouge as i have big hands

i`ll leave 24 hours between all three patches

mister p · 22 April 2013, 21:04

Exactly, don't need it opened up just made workable. and then..........take your time and prepare and clean.

the inner patch was a nightmare to work the glue on the inside but i took my time i used some ibs 2 part stuff.

i closely followed the intructions and stuck it in or on, i glued the `filler patch at the same time as glue was everywhere .

i left it for 24 hours and blew it up today yayy no bubbles on the drip test, whilst partially inflated i applied the outer patch and deflated the boat. i`m really pleased the inner patch was so effective as i felt this was more important than the outer patch

its funny as a local chandlery quoted me £50 for a patch and said i didn`t need an inner one,err all the advice is its needed even if its only 80% effective

the only thing bugging me now is where the old patch was there`s pen marks and some glue which refuses to budged by acetone i wonder if mek might do the job ?

mister p · 28 April 2013, 18:45

That's why I said don't worry about going "big" with the outer. Covers up others' sins.

Acetone's not that good. MEK probably will shift it, but it'll melt the tube a bit

I'd oversize the outer patch too.

You could try gently using one of these:-

THey get hypalon glue off quite well. Not sure what it'll be like on PVC though. I'd try it by hand before using a drill.

haha your crazy i`d have no boat left

Nos4r2 · 28 April 2013, 20:27

You'd be surprised. They are softer than you think-much like a slightly stiffer scotchbrite pad.

I posted this repair guide a couple of years back on this forum which I made for the old man's inflatable shop website. I've now transferred the link to another site because it's still a good guide to relate to.

This one is the large hole repair guide. There's also a floor repair guide. :-)
