stick it to the floor and watch me roll

Below is the vapor barrier of 4 mil plastic that will act as the vapor barrier between the floor and the floor framing.  I just rolled it out and stapled it from front corner to back corner, being careful to pull the plastic taut at each bay.  It was kind of a pain, but just time wise.  Pretty easy, all things considered.  Also I added another 1″ of expanded polystyrene and used a hacksaw to cut this time.  Made things infinitely easier.  You sacrifice a bit of R value with the polystyrene but it has a plastic/foil layer to deflect moisture, and its way easier to push into corners as it is a bit softer and doesn’t snap if it bends.  It’s all a matter of how nice and square your framing is (mine wasn’t since I used some reused boards and some new) and how good you are at cutting straight lines 8 feet long with a hacksaw/utility knife.

Before I put the vapor barrier on, I bolted more bolts through the framing into the trailer.  This is the way to do it.  Even though the trailer had 10 or so 3/8″ diameter holes around the outside and some down the middle, these 1/2″ galvanized bolts are way beefier and better.  If I were to do this again, I’d just go ahead and skip using the holes as they are (3/8″), I’d buy a 12″ long 1/2″ diameter drill bit that can handle drilling through steel, and just make those holes a bit bigger and sink these bigger, badder-ass bolts through.  I feel OK though, I have about 20 bolts in all, around the outside, about 2 feet in on each side and then up the middle.  Be sure to measure and account for everything involved.  As you can see below, I didnt give myself much of a thread to work with, so I sunk the bolts into the wood a bit.  Once you get the ratchet on there, though, you can just crank em in.

I spent about 2.5 days straight doing the flooring.  Things I learned: use plywood no matter what, first.  Make sure if you use rough cut wood that you make your first laid board is your best 100% straight board and work everything to meet it.  Errors compound.  Use little slices of wood to fill out long cracks, and it can look OK.  Things I gained more skill in: using a circular saw to cut 1/2″ wide 12 foot long pieces of hemlock!!!!!!!

So the floor is on.  It’s rough cut hemlock, and it looks like the floor of a barn (I hope).  There are some pretty obvious “patches” where I had to fill in between cracks with slices of wood and I learned from it (and hopefully someone else out there will, too).  This is the first carpenter/lumber part that I did 100% solo.  It can get pretty frustrating.

Walls next, perhaps this weekend?
