Just purchased a new home built in 1915 with what I believe is original flooring (photo below). I also have two dogs which I know will cause a good amount of scratching, so was planning to screen and do an oil-penetrating refinish. However, in the course of my research, I'm having second thoughts because based on the bits of information I could find, a sanded and refinished floor requires a lot of ongoing maintenance. If I'm going to have to clear the furniture and reapply the oil finish every few years, I believe that I might prefer just installing new flooring and get the benefit of the aluminum oxide coating that comes with new floor planks (which means not having to recoat for a very long time).
Can someone definitively tell me what type of periodic recoating I will have to do if I decide to go with the screening and refinishing route?
