Without knowing exactly what went in to this finish, any recommendation 
that would work would be a lucky guess.  What exactly is the mixture of 
this finish coat?

I think this can be readily dealt with using repeated coats of boiled 
linseed oil, or one of the alternative drying oils such as tung oil.
Since I am not sure of the exact nature of the mixture this surface is 
made out of, I would recommend trying the linseed/tung/etc oil in repeated 
coats (a couple days apart, possibly longer if the weather is cool) on a 
small unobtrusive area to make sure it does what you want before doing it 
to the whole area.  When the oil dries it will bind the surface materials
together resulting in a fairly tough and very slightly flexible surface.

NOTE: Most natural oils will provide some tinting of the color of your 
surface, so if that matters, you may want to compare oils to see which 
give you the best result.
