Priming the back of wood siding
I have heard that it is necessary to prime the back side of the spruce clapboard that I am installing on my house in order to prevent rot. I do plan on having a 1/2-3/4" air space in between the siding and house wrap. Is this extra step necessary? Lots of labor and extra paint I'd rather do without. On the outer surface I will be sealing the knots with BIN oil based stain blocker prior to solid stain application. Thanks for your help.
