I would just seal the edge and a few inches from the chanel. Sealing does not do much but if you can get it to stop soaking up water through the edges that would be good. Varnish or paint or something like that. You have to find and fix the leaks.

I used a product called CPES (http://www.rotdoctor.com/products/cpes.html) on my floor that had some water damage. I got the recommendation from others who have used this product effectively.
