Zodiac repairs

Romeo34 · 28 September 2016, 10:53

So I'm going to repair the 470 tomorrow and I was just looking for a little help.

First question:
Can I just put a marine grade sikaflex on the little dings and scrapes on the boat. Mostly on the bottom. It's not for repair of air leaks its purely just to conceal where the fabric is starting show. I'll attach a few pics to show what parts I'm talking about. I was just going to bake it on thick.

Second question:
The air leaks are at the back near the transom on the cone shape pontoons. There along the seems all within close proximity of each other. Can I just put a big hypalon patch over it and glue it with that special zodiac glue? I forgot what it's called but it comes in a tin and uses a small bottle of other stiff to go with it.

Third question:
What are these things near the manifold attachment points. Are they over pressure valves or something? They are flush mounted and have velcro patches covering them.

Last question:
Should I do something about my transom? The paints got a few chips in it. If I do need to fix it what products do I use.

All input welcome. Thanks in advance!

Edit: If I'm well off the mark with my thinking tell me the best way to fix these problems.

1.) The official procedure for exposed support cloth is to fill it with glue, let it cure, then patch over it.

2.) Edge seam leaks are very difficult to patch. You can sometimes do so with thin fabric, then burnish it well to form a perfect "90 degree" angle against the seam. Pennel & Flipo ORCA 215 is a fairly thin and strength csm/neo fabric you could utilize.

3.) They're overpressure valves.

4.) For best durability, you should touch the transom up with a 2-part polyurethane type paint, with a flattener added. I used Interlux Brightsides w/ flattener additive on mine with good success. The paint is vital to protect the wood from rot.

For glue, you'll need a 2-part elastomer type chloroprene glue for use with inflatable boats. Bostik 2402 w/ Bostikure "D" is one of the popular canned variants available that you should be able to find.

What kind of patches can I use for the underside of the boat? I wanted something that was tough and thick like some sort of rubber.

More hypalon material.

You could add EPDM wear strips later if you want, but you want to patch it first.

Where abouts do you live? If it's NSW I would get in contact with these guys for the right materials Boat repair Gymea - Inflatable Systems can get you back on the water

You don't want patches coming off when hitting rough seas offshore.

SC4000 cement is great glue if you are repairing an inflatable that is made of Hypalon (not sure if this glue is any good for PVC).
