FIber Cement starter strip and house wrap details
Hi all,
I just finished resheathing an exterior wall on our house. The previous wall sheathing consisted of Masonite siding over 80's Tyvek over 1/2" blackboard. The plan is for Fiber Cement lap over Ben Obdyke HydroGap over 1/2" CDX. I noticed that the wall was set back 1/2" from the rimjoist/mudsill/exterior brick which I'm not used to seeing. I have attached a basic picture showing the wall makeup. I have two items I need to figure out:
1. I was under the impression that house wrap should not be in contact with masonry. Given the situation, where would the house wrap end at the bottom of the wall or how can it be terminated?
2. Does anybody have a good alternative to a starter strip than ripping something from scrap? Something manufactured?
I'm thinking (hoping) I might be able to kill two birds with one stone if I can find a metal/vinyl starter strip to attach to the mudsill. The bottom of the house wrap would overlap the top of the starter strip and I would have my kickout for the lap. Any thoughts/comments?
thanks in advance

I don't know where you are getting the idea that housewrap can't contact masonry. It needs to drop below the mudsill so that water drips off it. Or add a flashing on the bottom that covers the brick and let the house wrap cover the flashing. I generally just rip starter strips off a sheet of cdx plywood or rip them out of a treated 2x6. But I suppose you could use a metal vinyl siding starter. It might be the right thickness too. Might be a good idea... just costs more.

Hi,
Thanks for the response. Yeah maybe I was wrong about house wrap touching masonry. I was under the impression that the wrap should not be on a rough surface. In my situation, I guess my concern is two fold. First, that the brick is pretty rough and I'm worried with the winds we have here in North Carolina it will flap against the brick and shred over time. Second, the transition between mudsill and brick isn't always smooth. In some parts of the wall the mudsill is ever so slightly back from the brick. I'm worried about the house wrap resting on the sharp edge of the bridge and failing over time.
The attached pic shows what I'm imagining. The red being some metal starter strip and the blue being housewrap that terminates on top of the starter strip.
thanks!
