Refixing Transom Bumper Strip

Lazy Pelican · September 28 2016, 15:51

We have a B39 2006.
Sailing in heavy weather our transom bumper strip has come off - again!
I've previously reglued it using Sikaflex, but it's only a short term fix.
Has anyone successfully refixed theirs?

I have a B37 2006. During an Atlantic crossing I found my dock bumper streaming behind one morning, the sealant having given up in the heat (I expect). Fixed it with this: http://www.bond-it.co.uk/product/pu18/ and it hasn't moved since. Only used one tube and still have some left over

Bond it sounds interesting- more of an adhesive than a sealant.
A friend has suggested ct1 - has anyone tried it?

Sikaflex is the name of a whole range of products, I suggest that an adhesive (say 292) rather than sealant (291) should be used.

CT1 is a sealant similar to Sika 291, but cheaper.

I have replaced my b37 2006 bumper, using sikaflex 291.
I replaced bumper whilst boat was still in the water, so it was a two person job.

I've refixed using Sikaflex 291 several times. It usually lasts a season and then comes off again. The problem is finding something that will bond to the plastic bumper strip. I find that all the 291 is bonded to the boat but that the bumper strip has very little adhered to it.

This suggests CT1 is well suited for the job. Not sure if better than Sikaflex 291 or just marketing blabla, I too assumed they were much the same stuff. Maybe worth a try?
