Knot Hole and Food Safe Finish
« on: February 27, 2019, 09:17 PM »
I don’t do much work that requires food safe finish.  The couple times I have previously I used “Salad Bowl Finish” that I picked up at a local Woodcraft.  It was easy to use and the cutting boards seems easy to clean.  I have a nice piece of black walnut (250mm X 850mm) and have been asked to make a charcuterie tray out of it.  I am planning to use the left over Salad Bowl Finish.  However the walnut has a knot hole I’d like to fill before finishing as I think this will make it easy to clean with the Knot hole filled in.

Any suggestions on how to best fill the knot hole in a food safe manner?  I thought about filling the knot hole with the Salad Bowl Finish.  Reasons being, I have that available and because when cured I know is food safe. I am in no big hurry so if it takes even a week or more to fully harden/cure that is not an issue.

I have read conflicting stories on epoxy as a food safe option and just not sure the best approach.  Thought I would seek some advice on FOG. Thanks in advance.

I have zero experience with either epoxy or food safe finishes, but since nobody else has answered, I will give my opinion.  I would reach out to the manufacturers of the epoxy and ask them about the food safety part.  I was once told that any type of finish that hardens, once hard is food safe.  I have never tested the theory due to no need for my projects.

Another option would be to check with Woodcraft or Rockler if you have one in your area.  Or better yet, reach out to the local woodworking guild.  In either case, I am sure they have come across the situation before and would be able to give you options.

The only way to effectively make the knot hole food safe is to remove it.... Route it out and put a patch in.
