Deck sealant

[pennycar9]

We have a sixty year old converted MFV with larch planked decks which are no problem, but the coach roof and bridge wing decks are teak laid and occaisionally leak. I have heard of a product called COLAN (I think thats how to spell it) which is like varnish but is good for sealing decks and is expensive (is'nt every thing) Does any one know this stuff and can give me some help please [image]

Coelan is without a doubt the canine testicles of deck coatings. Have a shufty at the link and I suggest you do a forum search as there have been several threads on the subject.

Coelan

Yep. Coelan is the canine appendages, without a doubt :-

Have not had a deck leak for 11 years now, and the boat is still on her mooring, still being sailed at the weekends, now (27th December) with the teak brightwork all gleaming and the cabin DRY!

In the years PC (Pre-Coelan) it was rather like sailing in a shower and she would have been under a cover by November.

Horribly expensive, and you must follow the instuctions precisely, or disaster may ensue. But worth it? You bet!

I've just put it on my very leaky (unfortunately new) hatch. It seems to be working so far but haven't had it out in the sun yet. It's very shiny and quite slippery so beware. I've put 7 coats on my hatches, so it does get expensive and successive coats have to be on within 2 weeks or else you have to rub it down again. I also tried to make sure it was thinned very slightly with their thinners as it makes it easier to go into leaky cracks! It's weird stuff, looks like pink plastic! but easy to put on even for a novice varnisher. You also need their primer. good luck.

What exactly is Coelan? Is it that very expensive, very thick almost rubbery varnish? If so, how easy is it to remove? Thats the big question I like to ask before I go coating my boat in anything. Will it come off as easily as it went on?

Yes

Probably not, but as it's good for at least ten years why worry. Localised repair due to abrasion should be as simple as conventional varnish.

Have a look at this?

Hope it helps?

Because the sort of boat with a lot of varnishing is the sort of boat you keep for more than 10 years. Anyway, I can't really stand varnished decks. Painted, canvas or bare wood are generally the best looking options I think.

Well, you can do as I have done - apply Coelan to the bare teak decks and then apply deck paint over the Coelan, leaving the covering boards, etc, in Coelan. I think it looks pretty good, and is suitably non-slip.

 

[Woodlouse]

Nah. Not scraping the decks just to Coelan them. If the deck starts leaking we fix the leak, either by replacing the offending plank or recaulking the offending seam.

I added pigment to my Coelan so my decks look painted, not varnished. The advantage with this stuff is its flexibility. Wood expands and contracts under the influence of temperature, humidity and the boats motion. Coelan neither cracks nor lifts, and is vapour permeable, keeping the wood's moisture content stable.
