GLUING DOWN THE FLOOR
I used some gorilla glue to attach a layer of 1/4″ luan to the floor. The 1/2″ CDX alone made for a rather thin floor, it also had a seam running through the middle which was sealed only by the sheathing tape.
Here is the first floor piece in place. This will add a little more structure to the floor and give it a nicer surface. The CDX it’s covering is pretty rough.
Here I’m weighing down the luan to get it to glue in as flat as possible.
And now both halves of the floor are in place. More weight to hold things flat while the glue dries.
