Dennis you are wrong about pores are pores....You go too fine on that sandpaper and you close the pores up so tight that the stain won't take (ends up being way too light) Put the finish on too soon and you'll have another problem (no adhesion)I've stained floors after a 60 grit cut and I see no problem( what's this peak BS?) you get enough coats on that floor and it will hold up just fine...As for the 3 coats of finish in 3 hours,this guy is a hack (if his first coat has crap in it then he's gonna have it through to the last coat.Try screening between coats,they come out smoother(but can't be done in 3 hours) As far gloss and satin finish (I use gloss as my underneath coats and top off with satin).
Well I've been wrong before, but not about wood technology, at least not that has been proven to me.
Peak BS? Nope, go back to floor sanding 101 if you need an elementary level education about the physics of floor sanding.
I suppose if you flood the place with urethane you will fill in the valleys between the scratch lines that 60 grit will leave.
At any rate I am not going to entertain an on-going discussion with you about right or wrong processes. What works for you is fine, for you.
In concluding my side of this "argument" so to speak, I have successfully sanded all the way up to 120 grit paper for many years, followed by hardplating up to 150 on occasion. Never had a problem achieving the desired colour because of a too smooth surface.
