Starting my flooring project...
 
First post here!

I just pulled up the carpet in a room in our house, and I'm planning to put in a hardwood floors in part of the house, and tile in the other part.

The room is 33' long, and 9'8" wide.

The front 1/3 of the room is concrete, and the back 2/3 is some type of plywood (large sheets).

In a couple of places, the plywood sinks down a bit (there is some give in the floor), but we jumped up & down on it today, and overall it seems solid.

Questions:

1) Do I need to strengthen the plywood in order to lay hardwood floors on it?
2) What underlayment do I need for hardwood floors (on top of the plywood)?
3) What underlayment do I need for tile (on top of the concrete)?

Thanks!

sounds like you need a sub floor down before the wood

if your using 3/4" flooring you should be ok. Run the flooring in the opposite diection of your floor joists.

What is a sub-floor? Is this the same thing as hardiboard?

How do I know which direction my floor joists are running?

Also -- a floor joist is the thing holding the layer of plywood up, right?
