I have a very old house on a slab that is a rental. I have a little
section of floor 4'x 4' in my entryway. Lifted up the tile and the
concrete underneath was crumbly. Took out the concrete and now I'm
down to wood planks. The wood floor is uneven - dips a good 2 inches
from corner to corner - and the planks need to be secured. The rest of
the room is carpeting. I'm sure I have some foundation problems but
I'm not ready to tackle that.
Do I screw down the planks, then level with cement, then use 1/2"
plywood before laying the tile? How do I get this even and create an
even surface for the tiles? What kind of leveling cement do I use? I
don't want it to crumble again.
