Bow rubbing strake

Jizm · 27 October 2005, 15:17

Can any of you lot give me some advice? I have noticed that the D strake on the bow of my rib has started to come away slightly. See attached pics. Anyway I would like to know the process for repairing it, ie what glue to use and the process etc? Just sling it in or wait for it to go off a bit before contacting the two surfaces? Obviously I don't really want to buy a gallon of adhesive for a tiny little job like this!!!!!
Cheers

I had a very similar thing happen to the strake on my Humber but down the side - I wanted to tidy it up and did the following.

bought a tube of bostic inflatable adhesive and cleaned out the gap as best I could with a piece of cloth.

Forced some glue into the hole and then squidged it all around until all surfaces where covered.

Left it to go tacky then pushed it back together and held for as long as I could - to my surprise it worked and stuck well.

This was strictly an amature repair and it was probably under less load than your example as mine was on a straight rather than a curve. but worth a try for a fiver.

There are probably better glues than this - I have heard people talk of bostik 2402 2 part adhesive which I assume is stronger but not sure if it gives as instant a bond.

250ml of 2-part glue and curative is around £9.00 (either Polymarine or Bostik type). As long as you get the ratios right, you can mix just what you need for the job. Measuring spoons and syringes come in handy here. The unmixed glue should keep in the tin for a few months.

Although it's a small area, I'd still go for a couple of coats (letting them cure off in between) before the final one. For a really pukka job, use 2 coats of PVC glue on the straking first before the Hypalon glue. You might have to 'prop' the strake and tube apart while they go off.

As Rogue says, make sure it is really clean first and wipe down with acetone or MEK. Draw a pencil line round the strake and use a small paintbrush to apply the glue.

Finally, when you do the final coat, get as much pressure on the area for as long as you can. Tricky in that position, but a block and a ratchet strap might do it?

Cheers guys, where do I get the 2 part adhesive from?

Most chandlers seem to stock the Polymarine stuff. Some have the Bostik.

Try and get two part adhesive if you can as it will last a lot longer.
