Separating from mirror modifier

Hello I was trying to separate my front boards from the mirror modifier by going into object mode then selecting the board.  Then I hit p to separate by loose parts.  It still selects all of the pieces not just the one.  I just want to alter so they don't look so similar.  What am i doing wrong.  Thank you

    You must first  Apply the Mirror Modifier in Object Mode. Then you can go into Edit Mode and press P > Separate by Loose Parts.
