we have a very busy household, 4 teenagers, dog, etc and our floor guy very highly recommended oil over water - we have three coats in the kitchen and two thoughout the rest of the house - it looks and is holding up beautifully....a friend has three coats of water base that is showing wear and tear after two years (less busy household...only two teens!) - yes you have to be out of your home for several days - but there was very little if any odor when we returned...

This floor was put in by an actual flooring company. It is the company that is contracted with this GC to do all his flooring. When He told me that I should use them because I'd get the best price, yada, yada, yada, he also said because "their installer/finishers were second to none". Now I want to ask if he knows this from his experience with them or because they told him that their installers/finishers were second to none! I was billed for "dustless" sanding & the GC has said the word dustless but neither the GC or the flooring company approached us to discuss how actually dusty the dustless is. I'm beginning to understand that you can ask as many questions as you want but if you don't ask the right questions, because of your lack of knowledge you won't end up with the information you need. Am I understanding both of you all's recommended course of action? I insist they go back and sand the floors-back to no stain? I do not ask the holes to be puttied except maybe the one in the photo below or similar, this one being dime size? I feel like this knot will lift out eventually. Then I make sure to start they are sanded properly, then stained, sealed or sealed, stained? Then poly'ed with sanding between coats. Total 3 coats. The boards with the deep gauges? The first pic really is quite deep & in a spot that will not be covered with a rug. It would be very difficult for sanding to get rid of the 2 places in the wood in the first 2 photos. Do I insist they be replaced? When you say problems with the short ends do you mean the cracks that show opening up from the show ends? Is the area in the center of the last photo lippage? The 1/2" linear sort of dome-shaped rise in the wood? As far as the humidity ect. We had small leaf acacia engineered hardwood installed in the bonus room last month by same flooring company. When the wood was delivered they did not want to bring it upstairs. I told them it was to be installed upstairs & delivering the wood early so it could acclimate make zero sense if it was not put in the room where it was to be installed. The wood was vertical stacked & left downstairs in unopened boxes. I emailed the owner/acts as install supervisor to voice my concerns about lack of proper acclimation ect. He said we would check the meter readings together before the install, although he did snidely ask me if I had a meter. Anyway, morning of readings were fine, inline with what I had researched as well as what he told me. The downstairs wood acclimated for at least 3 weeks, was not in boxes but was vertical stacked. We heated & cooled downstairs as normal during this time. Nobody offered to share any meter readings the morning of this install & I missed the owner when he was here at the start before he left. Sophie, do you still feel the issues here are from possible humidity/moisture or more likely poor preparation (sanding) & lack of dust control/cleanup before applying the poly finish? You know if you "dustless" sand & leave all the dust on the walls next to the floor being finished, pretty unrealistic to not think it 's going to float down onto the floor all day. Thank you so much for your input Cancork Floors & Sophie.

You are correct in that using a drum sander is not at all DIY friendly. But it's the only way to correctly sand a floor down to smooth and ready to finish. You will take years trying to do the same thing with an orbital. The rental rate for the sander is going to be more than hiring the right pro with the right equipment.

Aboritec is a quality product. Use their 2k ceramic finish. It's comparable to Bona's Traffic HD.
