Hardwood floors add beauty and value to a home. They’re warm and cozy, providing a look like nothing else can. But they’re expensive, so treat them like the investment they are. Whether made of oak, bamboo, maple, or a variety of other species and materials, hardwood floors need protection—and that comes from the best water-based polyurethane.
With so many flooring finishes on the market, though, it can be difficult to decide which is the right one for your particular situation. Knowing what product will last the longest for a given situation is a challenge, but this guide will help. It covers the top considerations to keep in mind and reviews some of the best options available.
What to Consider When Choosing the Best Water-Based Polyurethane for Floors
Whether the job is finishing a new floor installation for the first time or refinishing existing floors, choosing the right water-based polyurethane is important. The following sections will point out some of the most important considerations to keep in mind when shopping for these products. Be sure to read each section carefully to make an informed decision.
One of the most important factors to consider is a polyurethane product’s durability, since it has a direct effect on its longevity. Typical water-based polyurethane will last about 3 to 5 years at its maximum shine and performance, compared to a varnish or oil-based polyurethane’s 7 to 10 years. But that depends on a few considerations:
Areas that don’t see much sunlight or traffic can last even longer than the typical 5 years.
The best water-based polyurethane for floors comes in a few different levels of shininess, also known as sheen. Floor refinishers have a choice between high gloss, gloss, satin, and even flat polyurethanes in some situations.
Going along with the durability aspect, satin polyurethanes are typically ideal for flooring applications. These polyurethanes offer just a bit of shine, but they’re less likely to dull in areas where people walk. Also, the traction they provide over a high-gloss finish makes the floor safer to walk on without feeling rough or unpleasant under bare feet or socks.
Water-based polyurethanes are simple to apply. DIYers can apply the product to their floors with a paint roller, a roller sleeve designed for floors, and a brush. Still, there are some tips to keep in mind:
Water-based polyurethanes also feature less intense odors than oil-based options. With that said, it’s still a good idea to open windows for plenty of ventilation and to wear a mask during application.
Most floor finishes require more than one coat (three is really the minimum), so drying time between coats is a major factor in choosing the best water-based polyurethane. Some of the most convenient products feature drying times between coats as short as 1 hour. Others might take much longer, crushing the workflow.
Final curing time differs among products. For example, polycrylic dries very quickly after applying but can take longer than polyurethane to cure. Typically, these finishes might take only a few hours for drying between coats, but curing usually takes days. Most products are suitable for light traffic after 24 hours, and furniture after 72 hours. The finish probably still won’t reach its total cure for another week or two.
One of the biggest benefits of finishing flooring surfaces with polyurethane is that they become very easy to clean. With a coat of poly, even wood floors can take a good mopping without damage. Just be sure not to use too much water or soap, and the floor will be fine. That also comes in handy when cleaning brushes between coats.
When it comes to maintenance, keeping the surface clean from dust and dirt that will scratch the poly underneath is paramount. Otherwise, those particles will dig into the poly and wear it down. A regular sweeping should be all it takes. Also, a bit of floor wax can help restore some shine on a surface that might look a little past its prime.

Three coats of water-based polyurethane is the bare minimum to apply, but four coats is typically best.
Many of the best polyurethanes require sanding between coats. This is best done with 220-grit sandpaper, and it requires thorough cleaning of the surface between coats.
Most water-based polyurethanes take between 2 and 4 hours to dry between coats. Full cure depends on the product, but it can take from 24 hours to up to 7 days.
Yes, but the roller cover has to be smooth to apply the polyurethane uniformly. Any hard-to-reach areas will still require brushing.
Both polyurethanes work well for flooring, but there are a few differences. Water-based polyurethanes dry quickly and exude lower fumes. However, oil-based polyurethanes last longer and require less maintenance.
