I have a 7'6" room that runs the width of the back of my garage. I recently removed 6 feet of the wall that separates the back room from the garage in order to make a parking space for my John Deere tractor. I want to build a wall to re-enclose the back room (to separate it from the tractor parking area) as that is where I have my workshop.
The wall I need to build is not a load bearing wall so should I trim the ceiling drywall so the new wall contacts the bottom chord of the trusses or should I just have the top double plates of the new wall rest against the existing ceiling drywall?
There is also a strip where the original wall met the side wall that I will need to patch. I'm thinking about belt sanding a taper in the existing drywall, filling the area with a strip of drywall and then mudding it to match. The walls and ceiling are the knockdown texture so I'm thinking about spraying texture over the patch and then knocking it down with a drywall knife in order to blend it in.
Any hints/advice are appreciated!
