View Full Version : Cracked bottom-coating

4th June 2008, 04:17 PM
I just bought a used Formula X-186 Wood (2002). When I took it out of the water, I noticed that the bottom is full with longitudinal cracks. The cracks are less noticable when the board is dry, but they are still there.
The cracks are very thin, few centimeters long, come in groups. The lips of the cracks are bent out.
What to do?

I had the same problem with my F158. I sanded and repainted the bottom but the cracks reappeared before too long. Finally I got so mad that I sold the board very cheap and vowed never to buy a wood-finish windsurf board again.

Hi Ilan,
Not sure where you are located, but there is a fairly easy fix for this problem.
Check out Eva Holiman's "The Boardlady" site and get some of the penetrating epoxy she uses on wood finish boards.
The cracking you are seeing is caused by the wood in your board not soaking up the optimum amount of resin when manufactured to fully seal the wood layer.
The wood layer needs to be saturated to a certain level to prevent the wood from "soaking" with water, and for whatever reason the saturation level in your board is a little low.
So, get some penetrating resin, and refinish the bottom of your board.
If you cannot find any penerating epoxy resin, then I think Eva suggests a good 2 part polyurethane floor varnish, well thinned so it will "soak" into the surface of the wood and seal it.
This will stop the cracks.
Hope this helps,

Thank you for your reply Roger. I live in Norway, I doubt if the materials used by Eva Holiman are sold by the same name here if at all. I can ask people who deal with wooden boats.
Do I have to sand down the old coating?

Is it enough to treat only the affected areas, or should one redo the whole surface? Should one send down or completely remove the old coating? Does the board have a layer of glass-fiber outside the wood as some other brands have? Where are the instructions? How will it progress if I donít fix it?

You are shouting quite loud about the wood-technology wherever your products are advertised. I can't recall however any warning regarding the durability of these boards. It's the first time I have a wood-board and the first time I see this problem. Once I have shown it to others though, I learned that this is quite a common problem.

Invented in 1984, in mass production since 1994 (in fact, the combination of wood and water is known for mankind a bit longer than that). You must have had some clue about the water-absorption property of wood in 2001 when my board was in production. Now it's 2008. The problem is known for years, and all you can offer to a user of your product is to search for instructions somewhere else?
Sorry Roger, that's not good enough.
