There is a potential downside to a poly finish that isn’t an issue with wax.

Wax doesn’t react with the wood the same way a poly does, which is why this doesn’t happen with wax. Regarding this, how do you make colored chalk? 1. Mix up a batch of chalk. Using a ratio of 1 part warm water to 1 1/2 parts Plaster of Paris, stir together as much wet chalk as you want in a certain color.
