Good stuff!

I had small but irritating leak in the 'shop which let in the wet when the 'typhoons' blew in the Autumn last year. It's been sealed with silicone for the last 20+ years which isn't ideal, so I tried some CTI clear adhesive/sealer today (after having cleared out all the suspect old sealant) which was very pleasant to use and moreover, washed off me mitts quite easily...and it can be overpainted which is a struggle with silicone. It's four times the price of the silicone I used to use, but hopefully will do the job - Rob

Yes, it’s brilliant stuff Rob, I’ve done all sorts of things with it, most impressively on a bad joint in a plastic gutter, instant success.
Glad your lovely workshop is sealed up nice and tight again.

I use an equivalent called Hippo 3. It's brilliant stuff. One of its minor advantages is that it doesn't really go off in the nozzle. I'll be able to quickly get my half-used tube working again when I get back to the teardrop in a couple of months time. CT1 and Hippo 3 are both used by boatbuilders, for their long-term flexibility, and the ability to set under water. Great products.

Thanks chaps, the endorsement is very much appreciated. What I've done is to cut off the nozzle (I bought three tubes so have got another couple) once I used it, with some CT1 remaining in the nozzle. This forms a sort of 'cap' which I can then screw back onto the tube:



Between the 'cap' and the screw thread on the tube, there's a bit of cling film, so as the cap is tightened it will hopefully (with a bit of luck and a following wind) produce an air tight seal which ought to prevent the remaining CT1 from turning into a solid block of product inside the tube. This has always been the problem with silicone but as the stuff I was using was so cheap I never really worried about it.....however, CT1 is about £14 a tube from Toolstation in town so I thought it was worth making a bit of an extra effort to try and preserve what's left - Rob

Original sumogrip is as good as CT1 in fact it’s got a better cured high tensile strength but the thing I like best about it is it’s a lot cheaper than CT1

I’m another big fan of polymer silicone. I’ve found one that tools up nicely which is one of the negatives of CT1.
The only thing I’ve ever had it fail on is that horrible composit decking.
Apparently it also works under water.
