I need to find someone in the Saint John, NB, Canada area to help solve a wooden clapboard paint loss problem!

robnorthrup | Posted in General Questions on

We built a home twenty years ago and used wooden, cedar clapboards on the exterior. The builder didn’t strap over the Tyvek and we developed severe wall rot after a number of years. We literally replaced studs and sheathing and then used tar paper and strapped the walls etc., but we still cannot keep paint on any of our three buildings. The top of the barn wall which is outside of the in insulated loft is fine.

On our garden shed we removed siding, strapped the wall vertically, and installed screening vents at the bottom of the vertical strapped cavity and drilled two-inch holes at the top of the strapped cavity into the open attic space for air movement. We still can’t keep paint on.

    Rob,
    It sounds like you've been through some frustrating difficulties.

    How wide are your roof overhangs? For more information on the importance of roof overhangs, see Every House Needs Roof Overhangs.

    When you installed the clapboards did you apply primer to all sides? Not back-priming siding is a common cause of failing paint.
