Unfinished Circular-Sawn Douglas Fir Flooring

Posted: May 13, 2019

rough sawn douglas fir floorsSustainable Lumber Company is the industry leader in prefinished hardwood flooring. Although not advertised on our website, we produce and sell just as much unfinished Douglas Fir flooring. Our unfinished tongue and groove flooring with a circular-sawn texture has a beautifully organic look and feel, is highly durable, and is extremely affordable.

Just like all our products, we kiln dry our flooring to 6-8% moisture content, cut out all significant defects, tongue and groove all 4 edges, and grade to our 99% usable tolerances.

We lightly sand the original circle saw marks, simply to reduce prep time by the installer.

Unlike smooth floor options, our unfinished Douglas Fir tongue and groove flooring features live-sawn wood grain and authentic circle saw kerfs making the inevitable scratch, ding, or dent virtually disappear. This is especially important with active pets.

Since our unfinished circular-sawn Douglas Fir flooring is a solid 3/4″ thick, it can be easily refinished numerous times. If maintained correctly it will last the lifetime of your home.

Refinishing, when necessary, is simple:

  1. Clean your floor
  2. Lightly abrade the surface with a 320-grit pad
  3. Clean again
  4. Recoat with the floor coating of your choice.
