Natural wood floor refinishing

We were happy to find hardwood floors in surprisingly good condition under the old carpet.  The floors needed sanding and a few repairs and we wanted new hardwood laid in the back main floor hallway to replace the original tiles.  We hired a local contractor to sand and install the new hardwood.

We love the rustic, natural hardwood floor look but were shocked to learn that almost all widely used floor finishing products are toxic and release large amounts of VOCs. We knew that we didn’t want to use any renovation product that could be harmful to our health. I searched extensively for a natural product and settled on unrefined Tung Oil, which is a natural wood finishing oil used on ships in China for centuries. It took a few conversations to persuade Misha that using natural oil on our floors was a great alternative to polyurethane.  We bought the Tung Oil and citrus solvent thinner from the friendly folks from Homestead House http://www.homesteadhouse.ca/ in Toronto.  Misha was concerned about the maintenance and durability of the oil, but became a convert quickly as the oil application began.

Once the floors were sanded, Tung Oil was surprisingly easy to apply. The first two applications were cut with 100% citrus solvent to increase penetration and applied with buffing machines by the contractor.

The citrus solvent smelled great, but is a natural irritant, so I had to stay out of the house for a week, while it gradually evaporated. Misha, with the help of a friend, applied an additional 3 layers of pure Tung oil (without it being cut). Each application took about 90 min. to complete.  The result was a rich, bronze, matte finish that astounded even the contractor.

The contractor was so smitten by the look that he was going to recommend it to his clients.  Any scratches from pets or heavy use can easily be eliminated with the wipe of oil on a rag. One year later our floors looks like the day we applied the oil. The oil brings out the natural grain of the wood and we love the feel of the natural wood under our bare feet. Using Tung Oil as a floor refinisher was, so far, the best green renovation decision we have made.  By Mia

  1. Wood floor refinishing means when a home is already lined with wooden floors that have seen a lot of wear and tear like deep marks, scratches, stains, chipped tiles etc then these floors need to be sanded over with heavy sand paper and the upper coat of earlier finish and wood must be taken off.
