EMI Shielding EMI Board

Hi,
I am planning to layout a 2 layer amplifier+filter board and was gonna use the bottom as a path for my power lines and use the rest of the bottom as a ground plane for EMI shielding. My question is there any reason not to also cover the top layer into a ground plane also and etch away the areas i need for my circuit?
Thanks.

Just a question, does leaving the top unetched helps in EMI Shielding?
