Re: PVC fabric source?


The air deck is under much higher pressure than the tubes of an inflatable. The tubes are designed to inflate to about 3.5 psi and the floor 10 psi.

I don't know how to do the math but I'm sure the floor psi goes up when 1-3 adults + gear are on top of it.

How will that pressure affect a glue repair? I'm not sure.

I do know that it is possible to order the air deck from most manufacturers.

Keep gas off the air deck, it will destroy it (don't ask). Mercury Marine also suggested (over the phone) that I keep the deck covered to protect it from UV.

Re: PVC fabric source?

What are you doing sailing with bears in the first place....or did you store you food in the dinghy?

Re: PVC fabric source?

This discussion post is helpful. I have a similar repair need for a PVC has a 2' long tear in the front tube. Anyone know if the material listed below from NRS will work? It says for an AIRED floor and that it's 43 oz. I don't know if it would be fibre reinforced.

CrazyRu I have no experience with that particular adhesive.
However most of PVC glues I worked with can be reactivated with a heat. It becomes handy when you need to tackle difficult task of applying a patch from inside.
Basically, you apply glue, wait until it is not tacky anymore, slide patch inside, align it, stich the edges, then, using hair fan, or any other heat gun, reactivate a glue and press the patch and damaged area together. A little 1 inch roller is very handy tool for applying a pressure.

What glue?

Unfortunately I don't get to choose. I can't get hazmat ground shipments. Wish I could. I have been dieing to get my hands on some Smith's Epoxy sealer. I miss that stuff. Git-rot isn't anywhere near as good.
But I digress..

I am getting whatever West Marine sells. Since they have a store here I can get anything ordered through them when their barge shipment comes in. Looks like it is going to be a 2 part "Poly Marine Ltd" product.

camaraderie You need an internal AND external patch on gashes of this extent...besure to get enough PVC fabric to cover twice the area you need to patch.

sailboy21 Just got a huge chunk of PVC from Inflatable Boat Service and Supply
The guys there were very helpful, fast and gave me a great deal.
Now I just have to wait 2 weeks for the glue to get here....

GaryHLucas Ken,
I've got the material for repairing my dinghy. No poncho in the world would be made of material that thick! I also have one of those pools you speak of for my grandson. Same deal, thicker than the poncho but no comparison to the dinghy fabric.

You might try contacting some of the makers and telling them you need a large piece of cloth for repairs, and see if they can sell it to you or recommend a source.

You're thinking the $2. one-use cheapies you buy at walmart, many of the better sporting goods stores carry very nice heavy duty ponchos that are made with the same fabric as the dinghys.

Also, those free standing pools with the inflateable top ring have sides made of the same exact fabric. (easy set type, starting at $39. you'd get a roughly 30inch by 24ft length) bottom and ring are made the same as the walmart ponchos with no fabric, but the sides are very heavy duty with the fabric inside (able to hold 5000+ gallons of water!) Only real drawback is that they're only available in blue or white.

Like I say, I'm a big fan of buying things to cut up as material for a project. It's surprising how much more material you can get by purchasing a finished product than just buying the material.
(yeah I'm extremely frugal)
