Cutting Board Disaster
thewoodwhisperer.com What Happened? A few months ago, I woke up one morning, poured my coffee, and was incredibly disappointed to see that my cutting board exploded! OK so maybe it wasn't all that violent but it was cupped like crazy and had a very large split. Upon further inspection, I noticed a bit of trapped water in the center of the underside of the board. Now the thing to remember about end grain cutting boards is that even after finishing, they will still soak up moisture like a sponge. So standing water is your cutting board's Kryptonite! What Happened? So how does the split actually occur? Well let's think about what happened. The water soaked into the center of the board and as a result, the center "squares" swelled and expanded. Because the moisture was in the center only, the wood in the outer perimeter did not expand. So something had to give. The resulting crack is really nothing more than pressure relief. Think of it like surrounding a piece of solid wood in a frame. Eventually, the joints in the outer frame will open up if the board in the middle expands. The Epoxy Fix The first step in repairing this disaster simply involves waiting. After a few weeks, the board flattened out and the crack closed up almost completely. But the gap was still big enough that I wanted to use a gap-filling glue, so epoxy did the trick. Now I know what you are thinking. Is epoxy food-safe?
