Last night Cory and I finished up the flooring in the front bedroom (which is currently Amy's room), and pushed halfway into the back bedroom (which will be known as the office). In retrospect, Cory thought that we did too much. On waking up this morning, I would tend to agree. I didn't get much sleep, and my arms really hurt from pulling planks into place and "power taping" them (a technique that keeps the freshly glued planks from drifting away from one another). This is a technique that we discovered in the first few days of putting down wood flooring downstairs. Gaps were opening up before the glue had a chance to dry because of the shape of the sub floor. We also discovered scrap planks can be pressed up against the leading edge of the newly laid down floor and screwed into place, keeping any gaps from opening up as the glue drys.

Even after experiencing all of the hardships and cost of working with glue ($100 a bucket) I don't think that I would consider the use of nails, or installing a "floating floor". The sound that wood makes when an air gap exists between the planks and the sub floor is very loud and annoying. I'm very happy with the sound deadening work that was put into the sub floor upstairs. I am still considering adding acoustical cotton insulation between the floor joists to further increase the STC* and IIC* of the flooring as long as the insulation can be installed from below.

*STC (Sound Transmission Class) is a measurement that indicates how much noise is stopped (absorbed) by the wall or floor ceiling assembly. (airborne or voice noise)
*IIC (Impact Insulation Class) is a measurement that indicates how much impact noise is stopped in a floor/ceiling assembly.
Note: STC and IIC are logarithmic, like the Richter scale. Each 10 points represents a doubling of the noise reduction capacity of an assembly.
