plus we are kind of perfectionists when it comes to our house and we wanted to make sure we were taking our time and not cutting any corners.
we ended up using 4 bags of liquid leveler to help level out the existing floor and about 20 sheets of 1/2" osb as underlayment for the new floor.
we installed 18 out of the 19 boxes of hardwood floor that we purchased, approx. 720 square feet of solid hardwood flooring.
it took a lot of careful planning, but we were able to install the new floors so that they are at the same level throughout the house. standing at the front door and seeing the floor continue all the way to the back door makes me happy.
i am really happy with how the new floors look, i think that the color, width, and type are perfect for our house. i am amazed at how different the house feels now - it seems brighter, cleaner, and just more complete. it's hard to believe that we lived with the old floors for so long, with the stains, splinters, and all of the dirt stuck between the boards. it was so nice to finally really clean the first floor of our house on sunday, and to put away the air compressor and tools after 5 months of using our dining table as a work bench.
i think i'm ready to take a little break from house projects and just live in the house for awhile!
