"...I need the floors chemically cleaned (no sand needed, but deep cleaning instead) and several coats of lofty gloss polyurethane or suitable alternative." Now my quiz is, what procedure should i take for cleaning chemically, and is it risk-free for my health?
Answers: Considering the robustness risks and the possibility of damage to the wood (I am assuming hardwood floors) you are far better sour sanding.
I recommend have someone else do this for you who is trained and experienced.
