When it comes to applying polyurethane, nothing beats the precision of a fine brush. But when you’ve got a large project like hardwood floors in front of you, it’s understandable to wonder if there is a quicker and better way to do it.
The good news is there is a quicker way (using polyurethane roller) but is it better?
You’ll have to read the article to find out. We’re going to cover the following topics;
- Can you roll on polyurethane?
- What type of paint roller for polyurethane
- Best roller for polyurethane
- Applying polyurethane with a roller
- The best applicator for polyurethane
Let’s dive right in…
Can You Apply Polyurethane With a roller?
Yes! When working on floors and large furniture, you can use a roller to apply polyurethane (and definitely should). Applying polyurethane using a roller is easier, and the drying time is short. The roller also removes brush marks and prevents over-application on the surface.
The first thing you must know is the importance of choosing the best polyurethane roller.
What is the Best Roller for Polyurethane?
One thing you’ll love about using a roller to apply polyurethane is the speed. You can apply the first coat in your living room in minutes instead of hours with a foam brush. However, you must be cautious of lint and dust attaching to the wet poly.
In order to avoid this and other catastrophic results, you need to use the right roller frame.
When doing our research on the absolute best roller to use, we came across many varying responses from seasoned professionals. As a result, there is no general consensus. However, we strongly recommend (and others do too) using a lambswool roller.

Why Use Lambswool Roller
Yes, some professionals swear by foam rollers, microfiber, and mohair for finishes using polyurethane, but lambswool absorbs oil-based finish properly, and it doesn’t shed when you prepare it well.
Lambswool applicators are arguably the best choice for applying oil-based finish on the hardwood floor, so it tracks that lambswool rollers are also dependable.
That also points out an essential aspect of choosing the right roller: select one according to the type of poly.
For example, while you might get away with using a lambswool roller with water-based poly, you should not try it with a foam roller.
Of course, I won’t be surprised if someone has a technique that makes it work. But, despite the different styles and devices being used, the only thing everybody agrees on is that you should never use a cheap roller to apply polyurethane.

What kind of roller should I use for polyurethane
If you use a $1 roller, you’re going to see a lot of lint on your hardwood floor no matter how well you prepare it. If you make this mistake, the money you spent on polyurethane and the time you took to sand, clean, and apply the finish would have been for nothing.
When you use a good-quality roller, lint won’t be a problem, and the final coat would most likely take care of any issues with bubbles. Remember always to clean the roller with mineral spirits.
But if applying with a roller is risky, should you still use it? Absolutely, and here is why.

Advantages of Applying Polyurethane With a Roller
– Cover a large surface area quickly
Instead of spending days or weeks trying to brush a floor, you can wrap it up swiftly with a roller. Every swipe of the roller makes sure a few feet are completely covered, plus your nostrils won’t be as close to the fumes.
This comes in very handy when you are using fast-drying poly which we sometimes advise against using because they’re more prone to bubbles and it may be the only option you have.
– Yields an even finish
Rollers are the preferred tools for painting, so it makes sense that they apply polyurethane smoother and more evenly than a brush.
Rollers also deliver a pristine finish on floors that were not even or adequately prepared. However, that is not an excuse to not prepare the wooden surfaces correctly.
– No brush marks
It takes a while to master applying polyurethane finish on floors or stairs without leaving brush strokes. Fortunately, rollers don’t leave smears and brush strokes. As long as you follow the grain and prepare the roller right, you won’t notice any apparent marks.
– Used with different types of polyurethane.
Unlike when using a brush, some rollers can be used for both water-based and oil-based polyurethane. Of course, some rollers will perform better, and oil-based poly is best for floors, but at least you have the option.
Disadvantages of Using a Roller for Polyurethane
– Relatively expensive
A good quality roller costs more than a brush. Given that rollers also don’t last as long as brushes, it makes them even more expensive on a per-project basis.
– They can’t handle joints and edges
At the end of the day, or rather at the beginning of the project, you will still need a brush. But, of course, you might be able to get away with it on smaller planks you haven’t installed yet.
– Much harder to prevent bubbles
Polyurethane is bubbly by nature. When you use a brush, it is easier to prevent bubbles. Rollers, on the other hand, create bubbles as they lift the polyurethane during the finishing process.
What then tends to happen is you might still need a brush to smooth over your work after using the roller. However, you only need to do this with the final coat.
Can You Put Too Many Coats of Polyurethane?
When it comes to the number of coats, it doesn’t matter whether you are using a brush or a roller. While some professionals will tell you that you can’t put in too many coats of poly, I am not one of them.
At some point, you would need to factor in if the additional coats are making a difference or if you are just wasting money.
What we typically recommend is using three coats of polyurethane. If your polyurethane is not adhering in three coats, you either didn’t sand the wood properly or are using the wrong type of poly.
It is also worth remembering that manufacturers tell you how many square feet the quantity you purchased can cover. This usually maxes out at the second coat.
Just in case you are curious, this is what applying 40 coats of polyurethane look like.
Do I Need to Sand Between Coats?
No matter what you use to apply polyurethane, whether a brush, lambswool applicator, or a roller, you should never apply a second coat of polyurethane without sanding.
The only exception is when you are using a water-based polyurethane that does not need sanding – you can apply two or three coats of these with minimal wait time.
You need to lightly sand between the first coat and the next coat so that the following coat will stick to the previous one easily. Unlike lacquer, coats of polyurethane finish do not ‘melt’ into each other. You also need to sand to get rid of dust nibbles and bubbles.
The worst thing you want is to spend days on a project, only to notice you have dust stuck in the lower coats of poly.

What Happens When Lint and Dust Get Trapped in my Coat of Polyurethane?
Unfortunately, no matter how hard you try to sand and clean the wooden surfaces properly, dust can still end up in your wet polyurethane.
When dust gets trapped in polyurethane, it makes it look dirty, and so it will remain until you do something about it. For example, you need to know what to do when polyurethane doesn’t dry and cure as expected.
Now, to get rid of the dust nibbles, pencil marks, or to make your roller lint-free, use mineral spirits or you sand that part of the wood and reapply the finish. If you don’t trust the roller, you can use a bristle brush or apply wipe-on poly.
It can be a hassle walking around your floor searching for lint and dust, so you must take every precaution to be lint free.

Can You Apply Polyurethane with a Rug?
Yes, you can apply polyurethane with a rag. But, there are some important considerations to keep in mind.
When using a rag, make sure not to saturate it with too much polyurethane. Leave some polyurethane on the surface to allow for better control and to prevent excessive buildup.
Apply thin coats to avoid drips and uneven application. Wait at least 2 minutes between each coat allowing the polyurethane to bond before adding more layers.
Continue adding coats as needed until you achieve the desired coverage and a smooth finish.

What is the Best Polyurethane Roller Applicator?
The best applicator for polyurethane on a small project is a brush. It gives you more control, and the application method reduces the number of bubbles that come up.
