OK I explain. It is a floating floor what we call in the UK engineered floor, so it is not solid throughout but a thickness of the wood mounted on a plywood base. It is a Malaysian wood, not so hard, so I suppose high heels could dent it perhaps, it is not the hardest. It is a click system not requiring glue, interesting. Now from Malaysia it says it has five factory coatings of which some contain aluminium oxide. It got worn out over the years. So a year ago I sanded the wood with the machines with the correct paper and vacuumed well. Then I applied one coat of Bona Traffic silk, you know the glossy one. I then noticed a number of parts were very coarse to the touch. So after some hours I sanded again with slightly finer paper but still coarse. Now I applied again Bona. Once again certain areas were coarse to the touch and you could see stains. So now I did a final very fine sanding but this was by hand with very fine paper particularly in the areas affected. It took me hours. Then I applied the third coat. I called the Bona representative who was at a loss!!! He gave me a bottle of Bona "refresh" it is a type of product to do another pass over. I applied it to the worse parts of the floor. Although one could see areas which were coarse to the touch and which did not look quite right the shine was sufficient to fool guests for Christmas. Now I am exactly one year on. In those area I mentioned there are now black marks. I attach some photos of the present situation with example of the black marks. (sorry I do not know how to create a new thread). I want to sand it and apply Bona again before New Year when my mother is visiting, my wife will just about tolerate me sanding on the 27th Dec. I had the suspicion it was the Bona product maybe the bottle I bought was old or had been exposed to low temperatures where I bought it from but the Bona representative told me it was very unlikely to be the case.

I've been using Mega HD Clear on most of my white/light jobs and on other jobs where I was using regular Mega with the Mega Booster. It's working well. I like the slightly higher sheen in the satin (25 to 35) compared to Traffic (15 to 20) and the lower cost. Mega spread rate is 500' to 600' per gallon where Traffic is 350' to 400' per gallon. I personally like the lower film build that maintains more of the grain texture on the surface where Traffic looks too smooth and plastic. The Traffic must wear better and it's nice to tailor the sheen level to customer desires (semi gloss, satin, extra matte and naturale) but I think it's overkill for most homes. Before Bona introduced Mega HD Clear and re-formulated Traffic, their only clear non-yellowing urethane was Novia which is pretty cheap stuff. Neither finish should require an extra coat when new unless you think you're going to neglect the floor and are worried it will wear out. Most homeowners (at least the ones we work for) will recoat the floor after it gets scuffed, scratched and somewhat worn, but well before it wears through. The floor will receive the same amount of wear and need a recoat when it looks unacceptable, whether you're applied 2 coats or 20 coats initially.

I know this is an old thread but I felt the need to reply. We used Bona Traffic 5 years ago using spice brown stain followed by the Satin poly HD 2 part system. I remember back then it stated the darker color allow 12 hour dry time which we did. Then we applied two coats of finish. I recall that it took longer then 2 weeks to fully set and get solid but eventually it did and worked out great. Fast forward we got a new house. Great wood floors. Again we refinished them using the Bona HD traffic 2 part system in semi gloss. We used a lighter finish this time which stated on the stain can stated to allow 2-3 hours drying time in normal humidity. So this time around we followed the instructions and allowed 3 hours for the stain to dry on a lovely 75 degree sunny day. I did not go heavy on the stain and I would use a dry cloth to buff out the excess as I went along. Everything looked great. We have experience with the sanding so we spent roughly 10 hours using the different grits down to the 100 grit as the final step as instructed. Floors were lovely and down to the bare unadultured wood. We then vacuumed them and got every last bit of dust off using special footies as to not contaminate the floor with our feet. We could not have followed the instructions more perfectly. In fact we researched for a week and spoke to a floor refinishing company just to insure we did things 100% correctly. Well here we are now, 12 days in and I can scratch this off with my nail in many places. I am not talking just a scratch in the wood, but a peeling of the top coat scraping down to and exposing bare wood. I am sick to my stomach. The floor will not last. It is supposed to be strong like for a gym. This would not hold up to a room of infants. We luckily were finishing in a vacant home so nothing was placed on the floor for 10 days. It's not even worth moving all of our heavy furniture and starting over so I am going to put laminate floors over top of this and be done with it. I called Bona and they told me that they suggest 8 hour stain drying time. Well then why the heck would you state on your product 2-3 hours? Human error on my part? I think not I did everything that Bona said. Disgusted with the product. I should have used a cheaper oil base from the big box store. Biggest regret of my life. Perhaps Bona stored the product in a cold warehouse? Maybe it was a faulty batch with bad hardener? I have no idea but it behaves like something that did not have hardener. However I checked the unused bottle the next day and it was solidifying in the jug. Something failed and I can't understand what because I followed Bona instructions to a T.

i just got the matte finish on plain old (new) white oak in my kitchen remodel. They used amber stain because they said it would match rest of house best (old white oak floors that have yellowed). Even though I might have preferred lighter I was OK with that. But decided to hold my ground and asked them to use the matte finish which the floor guys were sort of against. I love the finished product!! It's super smooth, no shine and makes a more modern clean look. It dried nearly instantaneously and they did the whole thing in a day from sanding to top finish. Amazing what new products and technology have done to transform floor finishing. (I last had floors done in around 2001 - big mess). I sure hope this stands up because I love the look. I recommend it. And no smell at all after it dries (same day!)
