I had water damage to my home from ice dams that formed in my gutters. One of the results was I had to pull up carpet and particle board from my bedroom floor exposing the old wide plank pine floor which I love. Though I like the old worn imperfect look, there are gaps, dents and some old stains. I need to protect it, finish it and fill in the gaps. There is no stain or finish on it. What is the best and easiest way I can do this myself. Any help out there would be so appreciated.
