What is back-priming and why is it important that I back-prime my siding?
 

Most manufacturers of solid wood siding and exterior wood finishes recommend back-priming. Back-priming refers to applying a finish to the back of the siding before installation. All edges and ends should be treated as well. Back-priming provides additional insurance against extractive bleeding and dimensional instability or cupping.
