need advice - floating floor using underlayment

I am not sure how to proceed. my drywall stops about 1" from the ground. Is that normal? and then there's about a one inch gap between where teh drywall ends and a wood worder. So, in theory, I could lay the wood under the drywall and even the wood underneath the drywall 1" before i hit the border.Is that normal? I didn't measure the roms for this extra inch of hidden space on either side and i'm worried that leaving the 1 inch gap may be too much space if i just measure my quarter inch expansion gap from the imaginary line if my drywall had continued to the floor.

I laid the underlayment but am not sure if I should just turn the underlayment up the wall where the drywall starts OR psuh the underlayment all the way underneath the drywall until it hits the wood?

This is important becuse it impacts where my quater inch expansion gap will go.

In short - I have 1" high by 1" deep gap from where my drywall ends. Do they intend that I run the wood under this gap and measure the quarter inch under the drywall or - am i supposed to measure my quarter inch expansion gap from the imagineary line if the drywall had run to the concrete.

this is thomasville engineered wood floors floating on concrete.

Yes, this is normal.

Yes you can do this, just keep your edge gap (usually 1/4"). This will actually look better with the baseboards on.

Just lay the underlayment to the edge of the wall.


Good luck with your project. Just adhere to the manufacturers instructions so you don't void their warranties.

On a slab, if it is below grade, it is sometimes required to run the pad and vapor barrier up the wall a couple inches. If your slab is above grade and has no current or potential moisture issues, you may be safe to not do this. As stated earlier, make sure you know what the manufacturer requires. As to the gap at the bottom of the wall, that is the way I install this stuff. I cut the sheet rock up if there is no gap and clean out the resulting void under the sheet rock, back to the plate. I then install the material so the edge of it is even with the outer edge of the sheet rock. This allows the material to move under the sheet rock, gives more expansion room than is required, and allows the base board to cover the floor the full thickness of the base. This way, there is normally no need of additional quarter round.
