WHEN to level a concrete floor

hunts318 | Posted in General Discussion on May 26, 2009 09:31am

Hello people.

Last week I was asking about leveling a concrete basement floor and got the product recommendations I needed.

Now the other thought:

Would you do it before or after you would plate out and or cut said floor for basement bathroom plumbing rough-ins?

Thank you in any regard,

Hunts318

    when, when the concrete still wet

      Or, at the very least, before you put the finished flooring down.

    Sorry, but I didn't read your earlier posts last week, so I don't know how bad your "future"  bathroom floor is. But, if you are planning on cutting thru your existing concrete floor to install your planned plumbing rough-ins, I don't think I would want to pour more concrete on top before I busted it out...more concrete = more work.

    As for "plating" I am assuming you are talking about framing for wall locations? There are a few things you can do.

    a). You can shoot your bottom plate tight to the existing floor, then add another bottom plate; shimed level. Then build your wall and erect in place. This method calls for 3 bottom plates and 1 top plate. It's wasteful and time consuming.

    b) You can shoot down your bottom plate tight to the floor, Install your top plate directly above, and  then stick build your wall one stud at a time, toe-nailing it in place. Each stud can be cut to the required length. It's time consuming.

    c) Use metal channel for your top and bottom plates, and wood studs for the studding. Shoot down bottom channel plate, Screw top channel plate overhead,  then gang cut studs so to fit in- between bottom and top channels; studs don't have to be  cut to exact lengths for this to work. You then build wall one stick at a time.

     Bottom channel should not rest directly on concrete...can later rust if in direct contact. Better to install "slip sheet" of felt paper or use foam termite shield wrap, or better yet, shoot down a wood bottom plate first then install metal channel plate . If using treated lumber for bottom plate, recommend using a "slip sheet" of felt paper between wood and metal to prevent corrosion from chemicals in treated lumber. This method is very fast and easy to install...but only as a remodel wall, not for bearing walls.

    If your project allows, I would rough-in first, plate second using method "c"and  then and only then, pour on floor leveler.
