Which Sikaflex for a febder strio?

[ProDave]

I'm shortly replacing the rubing strake around my boat with this http://www.ebay.co.uk/itm/160719778973?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

It's a snug fit over the "flange" that runs all the way round my boat, replacing a rather tired skinny bit of stuff that I'll swear is just an old hose opened up.

So I thought I would just stick it on with sikaflex as that's seems highly recommended for sticking things on boats.

But when I search, there are loads of different types, so which one do I need?

Thanks.

I used 292 to attach a new wooden gunwhale strip to a mirror clone grp dingy. It's a structural adhesive and sets solid.
A tad expensive at about £20 but it really works.

I don't need it to necessarilly be "structural" as the rubber strip fits around a flange all the way round the boat, so once fitted and secured at the ends, it will just stay there.

But I want it "glued" somehow as well just to be certain. that "glue" needs to be a little bit flexible and waterproof.

The ones that keep coming up in my searches are Sikaflex 291i marine adhesive and sealant, Sikaflex 291 All Purpose Industrial Waterproof Sealant, Sikaflex 221 and Sikaflex 521UV

Then of course there are the caravan variants, usually cheaper than the marine variants.

The other "problem" is I would really like it to be clear, so any overspill is not too obvious, but I haven't found clear yet, just black, white and "wood" coloured

There is Sabatack 750XL. Stays quite flexible. Cheaper than Sikaflex and doesn't go off in the tube.

Stixall Clear

I have used Sabatack 750xl to glue a pvc rubbing strake on to grp and the short test section I did was similar to the video posted. The pvc failed before the glue did!

The only clear adhesive I know of that might be suitable is this one:

Unfortunately they don't give any information in the technical section on what the strength of the clear version is which they do for the other colours. I have also used the white version of this which seems comparable to Sikaflex but at a fraction of the cost.

That is not intended to be stuck on. If you use Sika 291 or the Saba equivalent it will be on there for good. OK if that is what you want, but more normally it would rely on a tight fit on the flange to hold it in place. Don't worry about the colour. Mask the areas of the hull, let the adhesive cure and cut any overflow off with a Knife.

The marine Sikaflex users guide and the Marine handbook can both be found on Bluemoment.com at http://www.bluemoment.com/downloads.html

But if you warm the material and stretch it tightly round the gunwale I think you will find that is all that is required. That is how the rubbing strake is fitted to my Sea Wych
Its a similar section material although it does clip over the heads and the nuts of about 50 bolts though the flange



FWIW here are the instructions from the Sea Wych building manual

Thanks VicS that looks interesting.

I had considered just stretching it round and nothing else, bit if it ever did spring off, it would be near impossible to get it back on again. Hence I feel the need for a bit of glue.

Also I plan to insert a reasonably generous bead along the "bottom" of the U profile of the strip to give a decent bit of extra cushioning, That Stixal looks like a contender.

Up to you but its been on my Sea Wych OK for 34 years after following those instructions
