PVC basic raft repair 

Most important thing: which glue one have to use. Is there glue in a tube you can take with you?

Key component is a glue. If you can provide that information it would be appreciated. Thanks

Thanks for sharing this video. I have placed more than 100 patches on airtracks for gymnasics. I love to see, that you use pressure on the patch while the glue cure. I have learned to do that by a experienced manufacturer of inflatables in general (not only for marine). But I have studied more than 20 procedures for patching on internet, and almost none use a pressure method as you and I use. I have had good results with pressure applied via small sand backs to distribute the pressure on the patch. Then I use quite heavy pressure of about 100-200 kg via clamp. By the way, I do not sand surfaces and only use one layer of glue. I think the pressure makes a significant difference. For difficult double curved areas along joints, I use sand backs on both sides and not too large patches. More patches may be needed.

How repair my value which is leaked provide me tools and instustrutions as soon as possible

The problem is that you don't show watch mechanically preparing a patch means, as well as chemically preparing. You don't show much of what you're doing. Just a whole lot of talk. Not very helpful
