I moved into this house about 10 years ago. It's now time to replace the carpet in the living room. I've decided to go with laminate. The kitchen had laminate when I moved in- looks pretty new. How do I go about matching the living room with the kitchen? Or do I need to? Thank you!

We finished an old (I suspect original) oak floor in the master bedroom of our 1910 house. It had carpeting and when we lifted a corner we found the hardwood floor. Turns out SOMEONE at some time in the past decided it would be a good idea to texture the ceiling and that they didn't need drop cloths. So when we exposed the floor it had white paint, texture, dirt, some kind of other smutch and all sorts of yuck. In addition it had been sanded at some point, and PARTS of the floor had a coat of varnish, while other areas didn't. We got all the stuff off the floor, cleaned it a couple times with denatured alcohol, scuffed it with 100 grit sandpaper and put our first coat of Minwax semi-gloss polyurethane. It looked UNBELIEVABLY good. We thought it would be so-so, but the varnish blended and covered and the floor looked amazingly good. So, NO problems with the wood, the floor, the old whatever, or anything else. Scuffed the whole thing with 220 on a pole sander, cleaned with denatured alcohol, and put the second coat on... And NO, we did NOT shake the can of varnish...... Looked even better. Any imperfections from the first coat blended, covered, and the floor looked fantastic. No runs, no drips, no bubbles, no problems. Let it dry again for 12 hours, scuffed it with the 220, cleaned with the alcohol. Our first 2 coats finished off the original gallon so we opened the second gallon for the third coat. And STIRRED it well. NO SHAKING... Applied the final coat... AND GOT BUBBLES. Tiny, little bubbles that you can see if you look just right. And once you SEE 'EM, you can't STOP seeing them. The only thing I can figure is the second gallon was slightly thicker or somehow different, even though it was exactly the same, bought at the same time, used within a reasonable amount of time... Followed all the instructions as far as drying, scuffing, and so on....... Bubbles. I can take a random orbit sander and use 80/100/150 paper to sand it down a little, and put on another coat, but what's to keep the bubbles from coming back? So, without doing anything DRASTIC, what do I do? Was the varnish too thick and didn't let whatever bubbles there were come out? If so, I can thin it, but how much and with what? Do I just scuff with 220 and put another coat on? Sand with 80/100/150 (or whatever I should use) and put another coat on? Help... I see bubbles! (which I may be able to ignore, but the domestic associate has commented on them, and she NEVER complains, so it's a problem).
