Chain plate sealer.

[Allan]

Over the winter, I may re-bed our chain plates where they go through the deck. The plates that bolt down to the deck are quite small so there is not much area to seal. Normally I would use Sikaflex. I'm now wondering if there are any better products available? One thing I hate about Sikaflex is that once it's open it seems to go off in the tube, no matter what I do to try to stop it!
Any suggestions?

One of mine needs doing. I will use CT1.

I had the same problem with a drip through around the chain plate bolts. I was advised to use butyl tape for all deck fittings, which is what I have done. It's worked well, butyl tape can be used on all through deck fittings, is relatively cheap, and never "goes off". So could be reused again and again if needs be. No more drips through the chain plates.

I never use sicker flex anymore, but CT1 and tek7 are good, especially in damp conditions where sicker flex won't work. Who ever had to repair a boat in the damp eh?

I had heard somewhere that keeping your sikaflex in the fridge extends the life in the cartridge? I much prefer using Bostik Simson MSR.

It doesn't go off in the cartridge and as an adhesive amazingly stong, as a sealer equally good being permanently elastic.

I am a great fan of Butyl Tape, works really well.

Island Packet chainplates are sealed with a General Electric product, Silpruf.

I will do mine next time with Butyl Tape.

I had an irritating seepage around a chain plate which I sorted with bitumastic gutter sealant (mainly because it was the only stuff in the local hardware shop that was anywhere suitable).

I think the freezer is the best place.

CT1 keeps for quite a while after opening, just dig out the "plug" each time you use it...

Yes. I have had some that had been partly used for more than a year on board and it was perfectly useable.
