I'm a renter and the hardwood floors in my apt. need to be refinished. My landlord wants a product that will stand up over time (hopefully as well as the high VOC oil polyurethanes she's used in the past). I have chemical sensitivities and need something non-toxic. What is the best-looking, longest-wearing, most non-toxic option?
