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.

There is only one genuine Black Walnut. Its grown here in the United States. Lots of companies will import lesser quality species from other countries and generically call it "walnut" Sam Gentry cabinets are genuine Black Walnut.

It would show up right away, not over time. Look into Bona sealers and urethane. They have three sealers that achieve various levels of a raw wood look, ClassicSeal, NordicSeal and NaturalSeal. These can be coated over with a non-yellowing finish like Mega HD or Traffic. The key to avoiding tannin pull is quite easy, apply the first coat very thin and make sure there's no runs, puddles or drips. I've seen people here recommend a few other products that maintain the raw look but I haven't used them and can't recall the names but if you search under NordicSeal at the top the threads should pop up.

I love it! The cabinet pic definitely looks better than the samples shot. I bet the white will help keep it looking light over the long term too.
