Things are coming together nicely on our Modern Farmhouse renovation/addition, including the floors which turned out beautifully! A nice good sand took out all that natural orange tone of the fir and we promptly stained it a warm, rich dark brown.
We tested a few custom stain combinations and this is where we ended up - not too light, not too dark. We were overjoyed watching it go on. Love the grain of the wood coming through the dark stain. Many people like fir in its natural state, but I think it is phenomenal stained dark. One guy applied it while the other followed him up to ensure even distribution.
We are so in love with these floors. Old-growth fir (and fir in general) is so seldom used these days, it really lends a massive dose of character and interest since the grain is so uncommon.
