I am replacing my molding/window casings, etc with alderwood moldings. I
have two "ledge tops " (one 1/2 wall at the doorway and one 3ft pass-through
to the kitchen). What is the best way to fasten/secure these two inch thick
alderwood shelf tops top the top of the surfaces without using any type of
screws/fasteners ? Would regular liquid nails do the trick ? Base of each
is regular lumber/drywall wall construction

Thanks, Tim
