Topix Underground

It was originally a covered breezeway between the house and garage, the POs poured a concrete floor and closed it in with big windows and short pony walls with doors center on either end but never used it for much but storage, I made a TV room out of it so I could see both the river and the front yard while watching the boob tube.

I have decided to spring a bit and cover the concrete floor with LVL but that will require molding on the two walls that used to be outside walls.

So if the walls are brick and the floor's concrete, you have to glue it. I suppose you will have to put weights on it while the adhesive sets-up.
Or you could glue and screw baseboard into the brick walls with a few tapcons and then nail the shoe to the base board.
