Kiln dried rounds splitting (lemmy.world)

Advice needed. I sanded the tops of these kiln dried rounds and then coated both sides with shellac. Most of them split a few days later.

The untouched rounds have been stable.

How can I make these smooth and shiny and keep them intact?

My guess is that the alcohol rehydrated the cells, causing them to expand and then shrink back. This might have introduced just enough stress for them to split.

What would be a good finish to use then?

I'd try spray-on lacquer.
