It has been torture waiting for plywood day! We put the upstairs floor joists up, and I thought the very next day I'd be getting a sun tan on a roof top deck.
Not so much the case ... we built stairs, backfilled, insulated ... just to name a few projects that had to get done as I tried not to glance up at those open floor joists ... and finally it's plywood day. (I'll be blogging about all the other projects we've been up to as well in the next coming bit).
Hooray for plywood day!
Every once in a while, I have been sneaking up to sit on the floor joist, just dreaming of this day! In my mind, there's even a waiter with a tray full of drinks with little umbrellas. We put the floor joists in in this post.
And this is how we lay the subfloor on top of those floor joists ...
On the tops of the floor joists, we measure and mark every 4 feet - this will be the plywood seams. Chalk lines are pulled all the way across all the joist tops at the 4 foot marks so we can check our accuracy with each sheet of plywood being attached to the joists. These chalk lines run the entire depth of the Momplex, perpendicular across each floor joist, every four feet.
The chalk lines serve as guides. When you are going 44 feet wide, if you get off 1/8" here, 1/4" there, a hair over there ... you'd be surprised at how fast that can add up to inches!
For subflooring, you use tongue and groove plywood. The tongue and groove are only along the 8 foot edges. On the four foot edges, your seams will fall on joist tops, so no need for tongue and groove.
But to start off, we will need to remove the tongue so the plywood is tight with the exterior ICF walls.
Pretty simple step here ... I just set my saw blade to the depth of the plywood and ran it down the edge, removing the tongue. Remember, you only do this for the first row of plywood.
Sheets of 3/4" plywood weigh as much as 90 pounds!!! I was so thankful our cousin Justin was here to pack plywood upstairs. We started first with a 1/2 sheet.
Tell me, does anyone else feel like they are getting stretched apart hauling a full sheet of anything? Here's wishing plywood was like 45" wide, or I was like three inches taller.
Then when we went to put the remaining piece in, everything keeps to the pattern, fitting just right, like a perfect puzzle, only the pieces are 48" x 96" and weigh 90 pounds. Not exactly a Melissa and Doug puzzle!
