Proper flashing at the bottom of hardie siding and tyvek. One of the things i noticed in the destructions is hardie s recommendation to use joint flashing for the color plus line. Hardie plank joint flashing tyvek or not questions for experienced installers i m just about to install my first hardie fiber cement job am bidding a second one. Did not overlap or kick out that bottom board it s actually flush with the stucco. I have several choices.

Slip in the flashing. Cut a slit in the sheathing wrap along the entire length of the water table and slip the upper leg of the flashing under the wrap see illustration. This bridges the framing sheathing wrb and trim joint. Lift the bottom shingle and slip in the kickout flashing.

If the kick out and step flashing can t tuck behind the siding screw on cap flashing to cover it then caulk along the top. For information on installations above 60 feet please contact jh technical support. And be capped on top with either a preformed metal drip cap or a custom flashing installed under the sheathing wrap. Hardie says it s fine.

Did not attach the hardie board to plywood so there s just the house frames them tyvek paper then the hardie board nailed to the frames. That joint should be protected. Minimum standard panel design size is 12 x 16. Or put at least one layer of grade d paper over the tyvek then the siding.

Or install a rain screen using say 1 2 x 1 1 2. Nail it to the sidewall or glue it if nailing isn t possible. Jamb flashing should extend at least 2 inches past the exterior trim because there will be a vertical joint where siding meets the trim.
