Follow-up on the sealing of a leaky keel
. I followed the manufacturers instructions with regard to multiple epoxy
pours to seal the TOP of the keel
1. Surveyed damage. "Leaky" but only held a gallon or two of liquid.
2. Cleaned and dried as thoroughly as possible. Used dehydrated alcohol to clean and remove as much water
3. Drilled the top of keel with hundreds of 3/8" holes.
4. Used Low Viscosity "Penetrating" epoxy
to pour small one quart batches into all the leaks
and drilled holes. (Took about ten single
5. Poured larger one gallon batches of the undiluted Low V epoxy when it was no longer "penetrating."
6. Used 60 grit to hit all surfaces and washed with alcohol then lacquer thinner before the final 5 gallon pour of the Low V mixed with silica.
Notes: Just like the manufacturer commented the keel is a huge heat sink. Bigger problem is getting the epoxy to kick rather than getting too much heat. By doing smaller pours it gives the epoxy a chance to thoroughly penetrate. By using dehydrated alcohol it soaks up all the water
. By using multiple small pours it is easy to access progress. By using penetrating epoxy it will still kick in water and also is thin enough to fill cracks.
Finally: It worked like a charm. It was also advised to me that when I haul later in the year to perhaps drill a few holes in the bottom of the keel from the outside of the boat
to drain any trapped water. But so far it's beautiful and worked great.
