After prepping the new 1x8 Toughboard composite with a couple of coats of stain, the first job was removing the old trim and the 1&1/2 inch wide CDX plywood sheathing firring strips behind it. Then I cut the vinyl siding back 3 inches along rakes using tin snips which was the hardest task of all. Wretched stuff and the man that invented vinyl siding ought to have his gonads nailed to the side of a barn.
Then I reinstalled the old trim as a new firring strips and started applying the new wider trim.
Each joint got a couple of biscuits in order to keep everything on the same plane with the lower edge floating over the vinyl siding.
Here is the finished job. The upstairs barn door and the garage door trim got a couple of coats of tan stain last week previous to replacing the trim. At some point I will replace the cornerboards as well.
