Glue for saildrive hull fairing

[Sanderling_]

Having tried both Sikaflex and contact adhesive over the years, does anyone know a foolproof way to bond the rubber fairing to the hull so that it is still there at the end of the year?

Thanks,
Tony

1. clean and prepare leaving a slightly rough key for the glue
2. Evostick
after trying sikaflex and others, good old evostick (after proving to B&Q that I am old enough to be allowed to buy it) is the best.

Mine fell off shortly after I bought the boat. It got caught on the propeller hub so I managed to dive under the boat and salvage it.

As Gardenshed says, clean and prepare. This is important. I roughed up both the rubber and the gel coat with some coarse sand paper to provide a key. I then stuck the gasket back on with a two part epoxy bought from Halfords. I think it was a Plastic Padding product but most would do. Make sure the gasket is held in place whilst the adhesive dries - not easy. After the gasket had stuck I filled the edges all round to ensure there wasn't a 'flap' that could catch in the water flow and encourage it to peel off.

It's been on for about 10 years now so I must have done a fairly good job.

I strongly advise against evostick because those who claim success have been plain lucky. Use a two part underwater/waterproof contact adhesive plus all the usual good preparation as stated by others. So important to get it right because failure can be very expensive!

Glue for saildrive rubber fairing

This subject came up some months ago and although good preparation is the key, there are probably alternative adhesives which will work well. One suggestion was CT1, available from builder's merchants I believe.
(it is on my shopping list).

Cheers,

Michael.

Thanks guys,

Someone else had suggested CT1, I shall give it a go.

Bostik 2402 is the stuff to use. Couldn't find it locally, I bought from an internet seller who turned out to be Barnet Marine Centre, www.ribs.co.uk .

I fitted mine, a genuine Volvo one 5 years ago, its still there and shows no sign of wanting to say good bye. It is stuck on with ordinary Evo Stick. Like many jobs like this, you can use the most expensive glue money can buy, but if the job is not prepared properly, its all a waste of time.

To attach the fairing properly, firstly ensure there is no trace of antifoul or paint on the hull where the fairing will attach, leave a good border, clean back to gel coat, abrade the surface and clean with acetone, or cellulose thinners, I expect meths would work just as well. Give the same treatment to the rubber fairing as well, rough up the surface that will contact the hull and again degrease with a spirit based solvent. Using the Evo Stick EXACTLY as per instructions on the tin, apply and then fit the gaiter to the boat. After 24 hours to dry, prime and then antifoul. Like I said, mine has been there for 5 years now.
