Before the poly could be applied, we sanded down the raw washed surface. This will be done a lot! If you will notice, that sander Jim Bob is using is t-i-n-y!
After sanding, Jim Bob had to go back and wipe all the saw dust off the floor with a damp cloth.
The top/right side shows the first coat of polyurethane on the floor. The bottom/left side shows the raw floor. You can really tell how the poly makes the wood grain pop! Of course, this is wet and it won't look this shiny after it is dry but maybe it will look close after 4 or 5 coats.
One coat of polyurethane complete. Four more to go.
