I am planning on raising a floor a floor on a current cement floor in a small room (100 sq.ft). This was a porch at some point and the cement floor has a pitch away from the house, so I plan on leveling the floor at the same time.
Assuming my plan makes sense, I would run the furring strips away from the house, one end would be about 1/2" thick and the other end, thick enought to achieve a level floor (I predict no more than about 1" 1/2. Each strip would be gun nailed in the cement every 16" or so and plywood (1/2" thick) would be screwed on top to receive whatever finish is decided (carpet or laminate).
My plan is to start by snapping a line around the room showing the height of the level floor and measuring the thickness of each strip from there.
I'm looking for general opinions on the project and tips to get it done right? How wide a piece of wood should be used to support the plywood floor? What's the best way to cut each piece on a angle on the full length of the piece (about 8')?
Any other gotchas or specifics I should be worried/concerned/carfull with?
