COLOR: Oil based poly has an amber hue, whereas water based poly is clear. An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor. Water based poly dries much faster, and several coats (up to 4) can be applied in one day.

Similarly one may ask, is water based polyurethane as good as oil based?

Oil-based polyurethanes leave an amber glow and require fewer coats. Both water based and oil based poly offer good protection; the biggest difference is in appearance. It's actually the most durable hardwood floor finish. If you love the natural look of maple, apply a water-based (waterborne) polyurethane.

Furthermore, how long does water based polyurethane last? But, if you are using a mid grade water poly (or low grade), expect the durability to be significantly lower than oil based poly. When I say lower durability, I mean that it will scratch and peel more easily and it won't last last as long (often 2 to 4 years less, but everyone's wear and tear is different).

Similarly, you may ask, is oil based polyurethane more durable than water based?

Oil based polyurethane lasts longer than water based. There is no contest on the durability between the 2 options. Water based polyurethane has lower VOC's - which is a bit of an environmental benefit (more about that in a moment) - but because it has lower VOC's (Volatile Organic Compounds), it doesn't last as long.

Which is better oil based or water based varnish?

In the past, oil-based finishes were more durable than their water-based counterparts. Water-based varnish does not amber over time, and keeps the color of your wood truer than an oil-based finish would. However, it also “flattens out” the wood grain, and unlike oil-based finishes, does not enhance the grain.
