Whenever someone calls me to get a quote for floor sanding and they have engineered wood flooring, they often ask me if it's even possible first.. To be fair, it's an understandable question, you only have some 4 to 8 millimetres of real hardwood to work with.
BEST ANSWER: I just made a cherry and walnut computer desk and used this finish generals satin, and I used the 0000 after very lightly sanding wth a 320 grit paper I didnt sand until the 2nd coat was dry then appkied 3rd coat and it turnd out great the colors are vibrant and the grains looks awsome and the smell went away after 8hrs it smells great after 24hrs.i used a foam brush too.
As I have said many times before sanding hardwood floors by hand can be a lot of hard work. Hard work that can be alleviated with the use of a floor sander.. With that said, I have now spoken to way too many people that will be sanding their floors by hand no matter what.
The two coats of Osmo Polyx satin have now been applied and here are the photos of the result below. Osmo was applied with their 220mm wide floor brush (looks like a broom) and I felt like I was playing part in an olympic sport called curling.
I'd say the cost of your knee's, back, time and many sanding discs would easily pay for a day of hire... I'd also question if the result would be more varied (ie. you're only sanding small areas at a time, vs. hire equipment you make full length passes).
