A wooden staircase significantly increases the aesthetic value of a home. It has that sleek and modern feel that carpet flooring can’t provide. As a homeowner, ensuring that your stairs are well-protected is essential.

Different Types of Polyurethane

There are two types of polyurethane finishes, oil-based polyurethane and water-borne polyurethane.

Oil-based polyurethane uses mineral solvents as the base for carrying polyurethane solids. On the other hand, water-based polyurethane uses water as its base. 

A while back, oil-based polyurethane finishes were the industry standard for durability. However, in recent years, water-based polyurethanes have proved to be just as durable as oil-based polyurethane finishes. 

Let’s see how the two products compare.

1. Eco-Friendliness 

Oil-based polyurethane contains more volatile organic compounds than water-based polyurethane. Prolonged exposure to these VOCs can have severe effects on health. On the other hand, water-based polyurethane finishes contain fewer VOCs and are therefore safer. 

Oil-based finishes have a pungent smell, you and your pets should vacate the house during the application process.

On the other hand, water-based polyurethane has a non-offending odor and allows you to remain in your house during the application process. 

Verdict: Water-based polyurethane is safer and less toxic 

2. Drying Times 

Although oil-based polyurethane requires fewer coats than water-based polyurethane, it takes longer to dry. One coat of oil-based polyurethane can take up to 8 hours to dry. That means it can take up to 2 days to complete 3 coats of this finish. 

Water-based polyurethane is popular for its fast-drying times. With each coat drying in 2-3 hours, it is possible to complete your finishing project in a day. 

Oil-based polyurethane takes around 30 days to cure while water-based polyurethane cures in 7 days fully.  

Verdict: Water-based polyurethane dries and cures faster than oil-based polyurethane.

3. Ease of Application 

Water-based polyurethane dries faster than oil-based polyurethane. As a result, it is much harder to work with than oil-based polyurethane. The fast drying times mean you don’t get a window to repair any mistakes that arise during the application process. 

Since oil-based polyurethane takes longer to dry, it is easier to do repairs if you notice some mistakes. 

Additionally, water-based polyurethane has a thinner consistency than oil-based polyurethane. It, therefore, requires more coats than its oil-based counterpart.  

Verdict: Oil-based polyurethane is easier to apply than water-based polyurethane

4. Color 

Water-based polyurethane has a cloudy white color before application. After application, the polyurethane dries clear, a feature that allows the natural beauty of the wood to shine through. The finish remains clear and doesn’t darken or turn yellow over time.

Oil-based polyurethane has an amber hue to it. Its color tends to conceal the natural beauty of wood. Instead, it gives the wood a rich, golden glow that intensifies with time. In some cases, oil-based polyurethane darkens over time.

Verdict: Water-based polyurethane does an excellent job of highlighting the natural beauty of wooden stairs. 

Summary: The Best Water-Based Polyurethane for Stairs 

Polyurethane has all the features of an ideal finish for wooden stairs. Once cured, it acts as a plastic coat that protects wood from water and chemical damage. Some of the best water-based polyurethane for stairs include:
