First Coat of Polyurethane

Here are a few shots of the floor I just took. It dried pretty well overnight.

This one is with the flash

Same shot with just the natural light from the windows, no flash.

Also just the natural light...Looking in the door to the room.

It amazes me how well the polyurethane levels out and soaks in as it dries. It really seemed like the waxer was putting it on a little thick when I was applying it...But looking at it this morning it seems to be smooth and level with no puddles.

So the next step is to lightly sand this coat. When I did the living room floor I used the floor machine with a 100 grit screen for the poly sanding. Since I learn as I go along, this time I'll be using a 120 grit (or maybe even a 150) when I sand and I'll be doing it with my drywall pole sander (sanding by hand, not machine). The in-between poly sanding isn't like the previous floor sandings where I was removing the old finish and smoothing the floor, this one is just to help the next layer of polyurethane adhere to the one that's already on. So the hand sanding is better because it won't remove as much material as using the machine would. It will also make any sanding marks with the grain of the wood in stead of the swirls the big machine makes.

When I did the first floor, I actually broke the borrowed floor machine trying to sand the poly in-between coats (the plastic part that holds the screen on the machine cracked...Probably because the screen was sticking so much to the fresh poly). So this time I'll hand sand. Live and learn.
