$begingroup$ If you want to repair something with $ce{CaCO3}$, than it sounds like using glazing putty; especially near to wood. Vinegar however is an acid that will start to decompose the carbonate in chalk, yielding CO2. Instead I recommend either a mixture of (finely ground $ce{CaCO3}$ and water) -- like a paste, or lineseed oil. …
