What is Polyurethane?

Polyurethane is a flexible, resilient, and highly durable material that serves various purposes. When applied to wood, it creates a sturdy and clear plastic protective cover making it an ideal finish for a heavily traveled area like stairs.

Stairs often have to accommodate a lot of human traffic daily, and quick wear and tear would be inevitable unless there is a hard, durable layer of protection.

So, using a polyurethane finish will not only add to the appearance of the stairs but will also help to protect the wood from damage such as stains, water, scuffs, and scratches.

Essentially, if your wood is covered in polyurethane, nothing can penetrate it as it offers a durable, hard coat.

Factors to Consider when Buying Poly for Stairs

Before choosing the best polyurethane for stairs, there are some essential factors to consider to help you make the right buying decisions. Some of them include: 


If you’re already considering applying polyurethane to your stairs, you’re probably wondering, how many tins of poly should I buy?

The short answer to that is, it depends on the type of polyurethane finishing you’ll be using and the level of traffic on your stairs.

Stairs with heavy traffic will require a lot more coating to adequately protect the wood from damage which may mean purchasing more tins.

Furthermore, if you decide to use a water-based finish, your wood stairs will require a lot more coating than oil-based ones, and that is something to keep in mind. 

Both oil and water-based polyurethane have their strengths and weaknesses, which we discuss in more detail below. 


When it comes to highlighting the figure and color of your wooden stairs, oil-based products will generally achieve more color and definition. 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.   

Drying time

If you plan to finish your hardwood stairs without staying away from your house for a long time, you should be leaning towards water-based poly.

Water-based poly takes about 6-24 hours after coating for the stairs to dry enough for use, unlike its oil-based counterpart. 


When choosing a fresh finish for your stairs, appearance is also something you must consider. Likewise, it is crucial in the flooring process because you need to be comfortable with how much light your floors absorb and diffuse.

Remember that glossier floors would show more dirt and imperfections than matte floors. However, if you prefer a shinier look on your floors, a semi-gloss coat is a good option since it has nearly 55% luster. 


Most polyurethane products cover between 300 and 600 square feet per gallon. For much larger staircases or hardwood floors, then you may have to purchase more than one tin to coat the entire surface properly. 

Types of Polyurethane

Polyurethane is regarded as the most practical yet easily-available hardwood finish. Polyurethane surface finishes have two main types: water-based and oil based polyurethanes.

Both protect hardwood floors from damage, and you should choose the one you prefer based on your preferences and the job at hand.

Oil-based Polyurethane

Oil-based or oil-modified polyurethane is created by reacting common finishing oils with a chemical that makes the oil molecules larger.

These polyurethane finishes are often chosen because they are more economical and easier to apply on wooden surfaces. It also offers more color, depth, and shine to wooden surfaces.

Furthermore, just like oil based stain, oil modified poly offers high chemical scratch resistance making it well-suited for use on tables, countertops, floors, and furniture that will see a lot of traffic. 

Oil-based poly is popular since it enhances the natural color of hardwood floors, is water-resistant, and is versatile. In addition to that, oil-based poly is more durable because it contains a significant amount of Volatile Organic Compounds (VOCs).

It immediately gives the surface a darker shade or an amber hue when applied to the hardwood floor. This can bring out the beauty of the grain and make any dull wood color come alive.

On the flip side, as the oil-based finish ages, it continues to grow slightly darker every year, and this may make it less suitable for certain stairs types.

In addition, it has strong fumes, which could be hazardous and take longer to dry. You should therefore be keen when choosing oil based polyurethane brands to get the best product.

Water-based Polyurethane

As the name implies, water-based polyurethane uses water as its base or primary agent instead of oil (solvents) to carry the polyurethane solids. In the past, water-based polyurethane was considered less durable than oil-based polyurethane.

However, its manufacture has improved recently, so flooring professionals now prefer water-based polyurethane over almost any other finish. In fact, good quality water-based poly will last just as long if it is well taken care of.

Apart from this, a water-based polyurethane is a non-yellowing clear coat thus preserving the natural color of your wood compared to the oil based ones.

This is especially useful for certain types of wood which you don’t want to alter their color like gray, white & lighter wood.

Overall, water-based polyurethanes have become popular because of their low odor, rapid drying time, and easy application.

Satin or Semi-gloss Polyurethane for Stairs?

Satin polyurethane keeps wood looking new for longer periods and hides normal wear and tear of regular use; that is why it’s the best polyurethane for stairs.

When choosing between a Satin finish or Semi-Gloss finish for your stairs, consider your color preference, wood transparency and the degree of durability your stairs require.

You must first realize that the glossier your floors are, the more they show off dirt and imperfections. Therefore, if you want a subtler and more formal look for your space, satin will make a better option.

Satin reflects less light, giving your wood a duller, low sheen appearance. This quality makes it relatively easy to hide all the imperfections and dirt, which makes it a plus for homes with pets and kids because it is easier to keep clean and smudge-free.

In addition, satin isn’t as smooth as Semi-Gloss, so it’s less slippery, making it a bit safer to use on stairs. On the other hand, Semi-Gloss finishes are perfect if you prefer a shinier glossier look for your floors.

Since it reflects more light, debris on the surface will be more visible. Ultimately, you can choose any of the two but remember, the glossier the finish, the more it will show any imperfections and wear and tear.

How to Apply Polyurethane on Stairs 

Material/Tools needed:

  • Polyurethane in a can 
  • Sandpaper
  • Painter’s Tape 
  • Paint Brush
  • Tack cloth 
  • Lint-free rags 
  • Lamb’s wool applicator

Step-by-step process

  1. Using 120-grit sandpaper, sand the steps so the surface is flat and smooth. Then, gently brush the steps with a brush attachment to remove sanding dust and use a tack cloth to smooth the steps further.
  2. Apply painter’s tape along the trim of the stairs to protect the walls from polyurethane. Cover the bottoms of any spindles or other objects on the stairs that you don’t wish to get the finish on.
  3. Invert the polyurethane can gently about ten times before use, and repeat this regularly as you work. Do not shake the can as this will cause bubbles in your finish.
  4. Take your polyfoam brush, and dip it halfway into the poly. Hold it there for a few seconds, so it really soaks in and fills up the brush. Let some excess drip off back into the can, and then bring it to the wood surface.
  5. Apply a thin coat of polyurethane onto the wood stairs. Start at the top stair and work your way toward the bottom. Run the brush along the stair using long, uniform strokes. Move the brush in one direction only, i.e. in the direction of the wood grain. Back brush over any drips or pools of polyurethane.
  6. Leave the stairs to dry for two to 12 hours, or the time recommended on the manufacturer’s label.
  7. Allow the first coat of finish to dry overnight. Sand the stairs smooth with 200-grit sandpaper. Vacuum the stairs, then clean with ph neutral cleaner and tack cloth. 
  8. Apply a second coat the next day in the same manner using a clean brush. Do not thin the polyurethane when applying the subsequent coats. Let the second coat dry overnight. Sand, clean, and apply a third coat, if necessary. A fourth or fifth coat may be required to achieve the desired appearance, but first confirm the number of polyurethane coats you will need. Be sure to sand and clean the wood in between each coat. Do not sand the final coat of finish.

Is Polyurethane Slippery?

Although polyurethane serves a good purpose by helping to keep surfaces protected, some types of polyurethane may cause people to slip and fall.

Already, the smooth polished surface of hardwoods makes them quite slippery on stairs and using the more shiny and glossy variety of polyurethane will make your floors even more slippery. 

Therefore, to prevent accidents and injuries, you could go for anti-slip or anti-skid polyurethane products like the Varathane 200041h, Fixall Skid Grip, or Bona Traffic Anti Slip that are specially formulated to turn any surface skid resistant. 

Alternatively, you could opt for transparent adhesive slip strips, anti-slip sprays, and floor finishes. They will add some grip to your stairs without detracting from their appearance.

Stair carpet strips, anti-slip tape, and stair runners are other options but these will take away from the beauty of your stairs by covering part of them.

Ultimately, hardwood floors are beautiful, but they can also cause accidents. However, using some of the tips above, you can have a beautiful, shiny floor without putting your life in danger.

Frequently Asked Questions

What is the best finish for an oak staircase?

A simple way to finish oak stairs is with two coats of clear polyurethane, which brings out both the grain and the reddish tinge of the wood. You can further enhance the warmth by staining the treads before applying polyurethane.

For this, we recommend you use the Minwax 63010444 Polyurethane 

Can you polyurethane over painted stairs?

Yes, you can. By applying polyurethane to already-painted stairs, you can provide them with extra protection against heavy foot traffic that can cause the paint to chip and crack over time.

It will also give the hardwood a glossy sheen that makes it easy to clean. 

Here is the best paint for stair treads to use in case you’d like to go that route.

How many coats of polyurethane do I need on stairs?

In general, two to three coats of oil-based polyurethane are enough to cover a set of wood stairs. However, water-based polyurethane does not coat as thickly as oil-based polyurethane, so you might need four or multiple coats for maximum protection.

Are polyurethane side effects free?

Unfortunately, they aren’t. Uncured polyurethane can irritate people with respiratory problems. However, that does not mean you are putting anybody at risk. As long as you apply polyurethane correctly, whether it is oil-based or water-based, you and everybody around the product will be safe. It is also important to note that these side effects are more likely during the production process, not the application process.

What is the best varnish for stairs?

If you wish to maintain the quality of the appearance of your stairs, a clear water-based polyurethane varnish is the best option. Apply it with a brush to coat your wood and then apply a second cag coat within 24 hours and let it dry to create a hard and durable surface finish.

Brands of polyurethane that I highly recommend. – Minwax, Bona, and Varathene.
