Anyone Have A Suggestion For A Good Product To Repair An Inflatable That Won't Stay Pumped Up Over Night? Can Not Find Any Leaks In Tubes Or The Valves

1) Cialis.

Get a spray bottle and fill it with water and a little joy. Spray and look for bubbles.

I had that problem for about 2 years and then I used a "latexing" liquid, which worked GREAT. It never lost any air after I did it for 2 years until I sold it to Cy Manley on this forum. I think it was this stuff in bottle in the yellow box(click here) but I called my son in Chicago to find the bottle that's still on my basement workbench. When he gets the name, I'll add it to this thread.

I did it on a 700 lb. Seadoo inflatable jet boat, so I couldn't "rotate" the blown up tubes after adding the liquid, so I just deflated them by taking the valves out, poured in the right amount of liquid, manually gooshed the sealant all around the tube insides, put the valve back in and reinflated it. Note the web site above has various methods to spread it around inside.

The stuff I used was Inland Marine Inflatable Sealant. (click here)

It is absolutely great stuff and it lasts. I dont know if you can later deflate it without the insides sticking to each other, but I never needed to since it was always blown up or partially blown up for winter storage.

The liquid stuff works great. I had a whole area at the bow of my Avon that had gone porous. I poured the goo in, rolled it around a bit, and no more leaks!

Thanks for all your replies. One thing the Web Site doesn't really explain is, if I want to repaint as well as seal, do I need to seal the outside before painting if I just did the inside? Anyone? Anyone?

[Nonchalant1]

I didn't know you could repaint Hypalon tubes.

In any case, I'd do the sealer first so you can blow it up to normal pressure and keep it there for the painting. There will be no chemical reaction from the inside sealer to the outside paint. The tube separates them.

Yeah, are you sure they can be painted? It's hard to imagine ANY amount of flex agent additives being enough to keep paint on a tube.

[Capt Ratty]

Thanks guys for your thoughts. From the info I gathered, you can seal the tubes on the inside. Inflate and go. But if you want to restore your inflatable to make it like new, you patch all known holes, clean the outer skin, brush or roll on this sealer they have, wait one day, paint with a special paint for inflatables. The paint makes it look as new and the sealer is supposed to seal the tiny holes.
So I am wondering if I seal the inside, which I think would be the better choice, and I still want to paint it, do I have to seal the outside too? Maybe it makes the paint stick better. ???
