What would be the right stuff to set a marble ledge onto the 2 x 4 at
the bottom of a window frame? The old stuff was something white that
looked like mastic. Should that do the job or is there something
better?

Thanks for all input

construction glue (liquid nails) or silicone. the wood is going to move with
changing humidity, and anything stiff will soon break.
