Coelan teak coating

[Nauti Fox]

Friend of mine has teak decking which has a slight leak in several places and being a Cherman boat this is most inefficient and not permissable.
Anyone know if Coelan would work at sealing the surface, or any other suggestions would be welcome.
Thanks, Al.

Alec,

The teak deak on my boat is starting to become more akin to a sieve than a deck. I have started to fiberglass over it. If you use west system expoxy and mat, it looks like it has been covered with canvas due to the weave.

The only option with mine otherwise would have been to re - caulk, but the stuff is horendously expensive and the deck was getting a bit thin anyway.

I dont think Coelan would help much re sealing the leaks. Careful re-caulking at the site of the leaks would be a better idea I reckon

I have a teak laid deck on my sloop that eventually leaked even after re-caulking with cotton and Sika. I plied the decks with Coelan and 'no more leaks'. The stuff does need to applied after a good coat of the undercoat, and the top coat must be built up with over five applications. Less than that and it will split under moderate movement. The only trouble with Coelan is that it makes the deck look like it is covered in cling film. It can also be slippery so a final coat with silicon beads is advised. The other poroblem is the cost. But as it should last for 10+ years it works out cheapest. I don't like the glossy look on my decks so the next couple of coats will be with the matte effect and beads.
good luck
John

Thanks for the replies, I'll pass them on.

Well, it all depends.

My boat has a teak laid deck, meaning a deck made out of teak planks and caulked, not a thin layer of teak over plywood. The deck was structurally sound, but leaky, due to enthusiastic over-caulking during the previous 58 years, when I gave it six coats of Coelan, after sanding back, recaulking the seams and using the right priming coat after checking the moisture content with a moisture meter.

That was ten years ago and not a drop of water has come in since, anywhere over 37 feet of deck.

Like others, I do not like the appearance of a "varnished" laid deck so I painted over the Coelan with ordinary non-slip deck paint.

The mistake I made was to leave the covering boards and rails varnished; I should have done them with Coelan also, as I did two years ago.

If used properly it is brilliant stuff.

If your friend's deck is teak-over-plywood or teak-over - GRP, I would not recommend it, as there may be other things going on, i.e. rot in the plywood and moisture in the foam core (same effect as rot in plywood!) which applying Coelan would not cure, and which may require more substantial "surgery".
