New York City Wood Floors


A wood floor will need to be sealed and protected. There are durable floor finishes available that will protect your indoor air quality and look great in the process.

In North America, polyurethane varnish is used almost exclusively as a wood floor finish, but floor oils are gaining in popularity. There are a lot of benefits to oiled floors, especially with softwood which are prone to damage.

Environmental impacts and indoor air quality (IAQ)

Whatever floor finish you choose, different products will have different impacts on your home air quality and the planet. Like paints, floor finishes will contain varying levels of VOCs (volatile organic compounds), or if you’re a really shrewd shopper, none at all.

While the smell may be gone in days or weeks, the effects won’t be. It will take years before VOCs in any surface finishes stop polluting your air, which can cause or aggravate a multitude of health problems. And the production and disposal of these chemicals have a similar effect on the health of our planet.

Water based vs oil based polyurethane varnish:

Water based:

  • There is an option of gloss or satin
  • It dries quicker than oil based
  • It isn’t flammable or explosive
  • It usually contains less than half the VOCs of oil based products.
  • In the past they were not nearly as durable, but product improvements have made that difference negligible.
  • Cleanup of applicators involves only soap and water

Expect around 200 grams of VOCs per can of water based polyurethane; compare that with a low VOC paint which will have about 50 grams, or Zero VOC paint which will have… wait for it…zero!

Oil based:

If there is a ‘pro’ to oil based varnishes, it is that they can bring out a bit more colour from woods, and leave your floor a bit warmer looking in colour. As mentioned above, oil  has a reputation as being far more durable than water based. But since that isn’t the case anymore, any additional durability hardly seems worth the added health, safety and environmental risks.

Downsides include longer drying times and about 450 grams of VOCs per can. Cleanup is less than pleasant and requires solvents, leading to more chemical production and disposal. And oil based varnish only comes in a glossy finish.

Natural oils (linseed or tung oil)

Natural oil finishes come from renewable resources, like flax seeds and tung tree nuts. Floor oils are not generally as durable as polyurethane finishes, but are much more natural looking as they age, and they are much easier to repair. Lacking the hardened coating of polyurethane, these floors can be less resistant to water and more prone to denting.

Whatever finish you choose, it is pretty much a given that a softwood floor will get damaged unless you rope it off and only look at it. Scuff marks and dents on an oiled floor are arguably not nearly as offensive as those on varnish, so I’d still score a point here for oil.

Most commercial brands contain and release far less VOCs than varnishes, so for both environmental and health reasons, natural floor oil is the winner. Aside from that, it could be argued that additional benefits include aesthetics and maintenance.

Rather than stripping your home of all furnishings then stripping the floor and re-applying a finish, you can do a quick sanding of damaged or high traffic areas, rub on a bit more oil and be done with it. As for aesthetics, in this writer’s opinion there is no comparison. An oiled floor looks and feels so much more natural.

Both consumer demand and government regulations have led to a heavy drop in the amount of VOCs found in both paints and floor finishes. So ask a lot of questions when you shop, and let us know if you find a great new product, like we just did –

The first Zero VOC floor oil

If we promote individual brands, it is because they offer something unique for either health or sustainability reasons. Regarding floor oils, we have found only one so far that contains no VOCs – Monocoat by Rubio. It has only been available in Canada for a few years, and so far we have found a couple of distributors in Toronto only, but you can have it shipped anywhere in the country.

While it may seem expensive when priced by the can, it’s called Monocoat for a reason – you only have to do one coat. In fact, attempting to apply a second coat is pointless as the oil bonds with the wood on a molecular level and once it cures the wood will reject any additional oil.

Monocoat comes in at around 30 cents per square foot, and by the time you purchase enough varnish for 3 coats you will be well over 40 cents a square foot. Ultimately this means less work and less money for a great looking, easily repairable non-toxic floor.

Since additional coats are not an option, for bringing it back to life in the future and repairing high traffic areas, a second product is available called ‘refresh’, which is again a quick and easy application that dries in 6 hours. Small dents can be repaired with any leftover oil, as freshly exposed wood will not have the existing product preventing the bond from happening.

There is an accelerator that can be purchased with the oil, which speeds up the curing process if you need to get on the floor sooner. Monocoat is the greenest floor finish we have found, being completely plant based. The customer reviews we have found are great, and we now have it on the floor at the Ecohome office. Everyone loves it, the air quality is great, and after 5 months, high traffic areas still have water beading up on top.

At present Rubio monocoat is only available for purchase from the following two locations, let us know if you find it somewhere else.
