Finished my new garage floor

I've been wanting to replace part of my floor in the garage for a while. It's about 75 years old. The tongue and groove was getting bad, as there were spots I already patched. One of the previous owners, applied used motor oil in an attemp to preserve the pine flooring.

So, a few weeks ago, I found somebody online that was selling decent used pressure treated 3/4 plywood for $5 a sheet. Although I didn't need all 15 sheets, I figured I'd use it elsewhere.They had been used in some racking and had some holes from anchor bolts and the sheets ended up being 8'5" long.
The extra length allowed me to cut some of the holes off at the ends but still had a few holes in the center. Since it wasn't T&G, I had to add some blocking, so I narrowed the sheets from 48" to 44", getting rid of more of the bolt holes.

This is the floor before I started, you can see a couple of patches.

The easiest way to remove old flooring

Out with the old.

In with the new

I actually started this the area infront of the windows. I pulled the OSB off the walls and reinsulated it, I also added some foam insulation on the front wall of the crawlspace foundation. I then caulked all the seams, being the place was bulit in '37, not alot of it is square.

About half way done.

Looking from the other side

Finished, then it was time to move everything back.

A nice little stack of wood to keep the garage warm.

In this pic, you can see how bad it was getting. I fixed this when we first bought the place and it got worse. If you notice the difference in the color of the floor, that's where they used motor oil to seal the floor. Everytime I sweep the sawdust up from working on house projects, it'd clean some of it off. That's 9 years of sweeping to get it that clean.

Looks better. Can you park a car in there? Well now anyway, not sure I would have tried it with the other floor.

My garage used to be a gas station, this side was the convience store side. The cars get parked on the other side, through the doorway, where the wood is stacked.

More pics of the ex-gas station please!

The new floor looks good. Not to rain on anyone's parade, but unless there is something I'm not seeing, and unless you were investigating joist condition, or added insulation or additional support piers under the floor as you went, would you not have had a much stronger floor leaving the tongue and groove in place as a subfloor, and applying the plywood over top of it? Was finished floor height an issue? I know the blocking provides some additional flex support, but the t&G subfloor would have been highly desirable to have to me, for strength.

Well done with the blocking. That is a stout floor, and tight. Sikkens deck stain would make that look nice, and seal it as well.

Finished height was the biggest reason. If you look inthis pic, you can see another concrete floor. They added on to this side of the garage at one time, pouring a concrete floor. I wanted to match up to that floor level.

I was also thinking that some of the joists were in bad shape from when I had fixed a couple of spots. I was wrong, luckily, it was nothing more than dirt/oil build up in the joints of the T&G flooring.
