Screwfix OB1 sealant / adhesive

AVOID OB1
I found it to be RUBBISH!
I was fixing a water in-pipe in a toilet cistern that was weeping. I dried and cleaned everything. OB1 took 2 days to dry, and it still weeps! So everything is wet again - but it is supposed to be able to stick underwater; it is like trying to stick butter to the inside of a glass of water! I really have wasted time and money.

Which boat are you sailing? I've never come across one with a toilet cistern (other than a ferry maybe).
If you've got a tube that won't cure, take it back to wherever you bought it and complain. I'm sure they'll replace it.

OB1 is the best because if you strike it down it becomes more powerful than you can imagine.

I did but in fairness to MadEnglish at least he got the quote right. Apologies for thread drift, but I’ve sometimes wondered if Obi-Wan did become more powerful after Darth Vader struck him down. Seems to me he just went a bit see through and glowed from that point onward.

As this thread has been resurrected I'll add my tuppence worth. I don't know about CT1 but OB1 is no good as a sealant. I used it to run around the perspex windows on my boat (I know! I'm supposed to take them off and bed them back down properly) and it was no good. I raked it off and used cheap old silicone, much better seal but I have to say not perfect, I'm going to try another layer of silicone to see if I can get perfect.

I can't remember what it was but I have only found one sealant to add round windows to seal. If I was on the boat I could find the tube. 3M comes to mind and it wasn't cheap.

Sounds like important info - do share it please.

The best I have found is EB25 - as strong as sika, works on wet (sometimes, nothing is magic) much less prone to go hard in a part used tube and about £3 a tube less than Sika 291. Also UV resistant without paying £30 a tube for the Sika UV stuff

I will try to remember when next on board. It's a 4 hour round trip and looking at this coming week temperature's it will be in a few weeks.
