Has anybody used it? Is it any good? How do you apply it?

We have got a small leak getting in the boat some how when it rains and hopefully have managed to narrow it down to 3-4 places were it could be getting in. Either one of two portholes or the hooks which hold the tonneau cover over the stern to the cabin sides, so, i am thinking of giving them all a dose of CTCCC.

Is it a liquid that is applied liberally to seep into unseen cracks or something more like a silicon type application.

Yes, I've used it and it works. It is a thin whitish fluid that you apply to the crack and watch it run/wick away. Keep applying, allowing a small interval between each application, until eventually it doesn't wick away and then you are pretty sure that it has sealed the crack. I was always pleased with the results and it doesn't show like a gobbit of external sealant.

If its portholes that are leaking is it the seal between the porthole casting and the glass or the porthole casting and the shell? If its between the casting and the shell it might be worth taking them out and re-fitting them with new sealing tape or mastic. We had a leak round a porthole caused by a screw hole and fitting new tape fixed it.

There's a couple of builders I know that could use some

I like collecting recipes

I now have a greater number of recipes than the likely number of days remaining to me!

Personally I've found it the most useless sealant ever. It just runs away into a crack and disappears forever. It might be OK for miniscule, hairline cracks, but give me Marineflex every time for a real job.

Sorry if this is hi-jacking the post but it is relevant to the topic and not worthy of a post of its own.

Is Pratley putty available in the UK? It profeses to be a South African product but the South Africans are very good at saying they invesnted something that no one else has advertised inventing.

Anyway, the putty comes in a box 6 x 12 cm with two strips, one for hardening. You take same quantities of the strips and mix them together. Knead into a crack or apply to both surfases that require joining. As Strong as steel after 10 minutes.

Back to OP I have used CTCCC on one of my windows, I had a leak and used some around the frame, this is brilliant stuff as it cured the leak almost instantly and I wouldnt be without it.

I am a supporter of both Marineflex and CTCCC! I find Marineflex much better (and less expensive) than Sikaflex for general sealing but have known the occasional Marineflex joint to fail (usually on my roof prisms). However a quick application of CTCCC to the place where the Marineflex has lost its adhesion and the job is sorted.

Interesting stuff CTCCC. It looks to me (and smells like) a weak solution of natural latex. EG like Copydex glue or the stuff that was in those orange "glue pens" we used to have in the office in the days when "cut and paste" was much more of a literal operation!

For this reason I think it may have a limited life, especially when exposed to sunlight as like all natural rubber it will perish after a while.

However it is so easy to reapply if it does perish so I will go on doing that until the time comes to start again with the Marineflex and do a proper repair.

OK - sounds like it's a weak solution of PVA then which was my original thought when I first tried it. Still smells like Copydex though!!

Isn't the clue in the name though? Creeping crack cure will creep into cracks and cure where it cannot be exposed to sunlight so how is it going to degrade? There is nothing visible from the outside to the naked eye and that's why it is such a good product for the right application. It's not going to seal huge wide gaps, of course it isn't, but it's brilliant for those small fissures that would, otherwise, require removal of the fitting or a nasty in-decorative gobbit of sealant externally.

As I was wrong and it isn't natural rubber but some form of PVAc perhaps it won't be so susceptible to sunlight after all but in the case of my prisms it's often the Marineflex/glass adhesion that fails slightly so there is sunlight exposure there, albeit the UV content of the sunlight that does the most damage should be reduced by the glass. In other types of "crack" of course you're right. I'm not knocking CTCCC though, I have found it very useful.

Or try PVA glue as mentioned in this post


Evostik exterior/weatherproof 'Resin W' wood adhesive (blue bottle) is much less runny than the watery cheap stuff.

If you look at the instructions on the back there is a line that says 'inject crack using hypodermic needle'.

Read the next line, (In the next coloumn) it says "inject in crack using hypodermic needle for overhead operation"
