After I installed the insulation, I installed the interior walls.
The rest of the garage is lathe and plaster over the wall frame – this is the way my entire house was constructed way back when. The original garage burned down and was rebuilt in the early 1960’s, and lath and plaster construction was used then too. It is difficult to fasten things to a lath and plaster wall. Stud finders are confused about where the studs are actually located, and the laths can be pretty solid at times making it difficult to tell if you are putting a lag bolt into a stud or into a lath. I’m used to using nylon drywall anchors, which are much easier to install for shelves that will carry 10 to 50 pounds. And with drywall, it is easier to tell where the studs are too.
But this is a woodshop, so instead of drywall I just installed more OSB as the interior wall. I installed the OSB with the smooth side presented to the shop, but even so the OSB texture stands out. Still, it’s a woodshop, and I really didn’t want to spend time taping and mudding a drywall.
I then used standard pine 3/4-inch primed trim boards to frame my window and the interior frame of my doors. I held them in place with 18-gauge brads from my nail gun.
I trimmed the exterior using primed pine molding boards, framing the window, doors, and the entire new wall to hide the transition from stucco to the new wall. I used my nail gun to fasten the exterior trim. The brads held very well in the stucco and the concrete fiber board.
Next up I spackled in all the holes and gaps that I cared about. I used the “pink stuff” spackle. Then I called it a night.
The next day I spent an hour sanding the spackle smooth, and cleaning up the resulting dust. Then I prepped for painting – mostly by cleaning up dust and dirt so I wouldn’t kick it up while painting. Again, I called it a day – I waited to start painting so the dust would settle.
The next day I started using an interior / exterior latex paint for my new wall and trim. I used a white eggshell sheen. The white matches the exterior stucco, and the sheen allows for good light reflection inside the shop.
It took 3 coats of paint to cover the OSB. Parts of the OSB seemed to “seep through” the latex paint – probably due to the glue used to hold the plywood together. If I did it over again, I would either first seal the OSB, or use Kilz primer over it first. Something resistant to the materials used in the OSB. But still, 3 coats on the interior OSB seemed to do the trick.
The exterior concrete fiber board was already primed an ugly yellow-brown color. It took the paint willingly, and it only took two coats to give it a very acceptable appearance.
The primed pine trim started out white – and painting it white hardly seemed to make a difference except to change the sheen a little, and to hide imperfections.
Then finally I painted the wooden door sill a battleship grey, using paint that is designed to be walked on. After that paint dried, I sealed the door sill using a pure silicone grey-colored calk.
Tonight I’ve started the process of moving my bench up against the new wall, under the window. I’ll put my tool chests up there too, and sometime this week I’ll add some overhead cabinets.
Also, I’ve planned to add an outdoor garden shed for my lawn mower and other garden tools. It will go up against the new exterior wall, between my new window and the property fence. Then I’ll be able to evict the lawn mower and other outside tools from my woodshop! I’m looking forward to that! I’ll post images of that when I do it.
I’ve created a photo album of images that I have taken during this project. You can see this album here.
