My Crozy Shop Floor: Part II, The Floor Part
Before getting to the OSB, I fastened the XPS panels to prevent them from shifting. I secured each of the 2' x 8' XPS panels with two (2) Tapcons into the underlying concrete floor. That's not enough for permanent attachment, but since I'd be attaching the OSB through the XPS, it only needed to be attached enough to hold still while I installed it. I started every other row of XPS with a half sheet so that though there were many joints where three (3) panels met, there were no four (4) panel joints.

After the XPS, I installed the 3/4" tongue and groove OSB. I used a half sheet of OSB on every other row also to achieve the same 3 panel joints. Each sheet of OSB was fastened through the XPS into the concrete with 18 tapcons in a 4-3-4-3-4 patten, installed along the factory markings which are painted on the OSB to help identify where the framing is for typical installations. This left me with a floor fastened every 1.7’ on center. It shouldn’t be going anywhere.

With the XPS installed to 7-1/2” from the garage door and the OSB installed to 12” from the edge of the XPS I called it a day on installing the floor.

The next morning, after I picked up my new jointer, I began the long task of loading all of the tools into the shop by myself. By the time my wife got home in the early afternoon, the only thing left in the living room was my work bench.

Though I still need to build the threshold and tie it into the OSB I’ve spent the few weeks since the floor was installed painting the walls and setting the shop back up. In that time, I’ve already come to appreciate how nice working on the new floor is. When I step from the concrete at the door to the OSB I can immediately feel how firm and soft the new floor is.Though I’m far from finished, it’s absolutely delightful to be able to reach a
