I put down solid red oak floors (about 730sqft). I hired out the sanding because fo time crunch. Adrian drum sanded to 100 grit. I have never sanded a floor, but it looked pretty good to me.
I'm quite sure I over-did the prep after that. It took me about 4 hours to sweep the floors and prep them as I only wanted to do it once and get the best results.
I applied three coats of Waterlox Sealer/Finish on the wood with no additional sealers, stains, etc using a 1/4" foam roller. I wanted the tun oil look and the satin finish. The problem is that after 3 coats some areas still look "dry" after three coats. I'm not sure why. I hope the answer is that you just keep coating ti untill the entire floor "evens out" because Waterlox is expensive.
Any help would be appreciated.
