Applying polyurethane using a paintbrush can be time-consuming, especially when handling extensive flat surfaces. While paint rollers are the obvious solution to this dilemma, can you roll polyurethane on wood floors without risking the material’s quality?

In this post, our resident woodworkers will discuss the perks of using a paint roller and the cases when it’s not the best option to consider.  

Is it Okay to Use a Roller to Apply Polyurethane?

Yes, using a roller to apply polyurethane to wooden furniture or hardwood floors is generally okay. Compared to brush strokes, spreading polyurethane with a roller allow the application to dry faster. Besides that, a paint roller doesn’t leave brush marks or lines. 

And because it has a faster drying time, paint rollers naturally produce a smooth polyurethane finish. It also ends up with a rounder finished surface than other alternatives. 

Types and Benefits of Polyurethane

You may not know, but polyurethane paint comes in two types: water-based and oil-based poly. These products offer different attributes, so the type of polyurethane roller you’ll use will affect the final finish on wooden surfaces.

The first thing you’ll notice when applying oil-based polyurethane on a hardwood floor or other wooden surfaces is its thick consistency. Because of this, it can be well-absorbed by the likes of microfiber, foam, and lambswool roller options. 

Meanwhile, water-based polyurethane has a lighter flow than oil-based alternatives. The foam paint roller is made of porous material, so it could absorb excess poly, which may result in an uneven final coat. 

If you want an even and beautiful solid coating, you can apply water-based polyurethane using lambswool and microfiber roller kits. 

Advantages and Disadvantages of Using a Roller for Poly Application

Applying polyurethane with a roller offer many perks, but it doesn’t mean this method has no downsides. Here are some things you should expect: 


Covers Large Surface Easily

Most woodworkers spend days applying multiple brush strokes to ensure you don’t miss any spots. But did you know that you can make the roller cover your wood floor perfectly in a shorter time frame?

And because applying polyurethane with a roller requires less time, you don’t have to worry about extensive paint fume exposure [1] that can irritate your nostrils.

Even Finish

Since paint rollers have rotating cylinder designs, you can expect flat wood surfaces like deck flooring to yield a perfectly smooth finish. Its cylindrical roller sleeve allows users to easily determine if they’re applying too many polyurethane coats on the material. 

Our team’s experience suggests that rolling poly will deliver the same results even if the material isn’t thoroughly prepared. However, we don’t recommend applying polyurethane with a roller if the workpieces aren’t sanded. 

No Marks of Brush

You must be an experienced woodworker to leave no brush marks or paint streaks when using paintbrushes to apply polyurethane products. So if you’re a beginner, the best option to buy is lambswool, microfiber, or foam rollers.

As long as you use it properly and spread the polyurethane along the grain pattern, you don’t need to worry about paint brush marks. 

Can Be Reused with Other Poly Types

A multi-functional roller works well with oil and water-based polyurethane products. However, as we said earlier, not all roller types will perform the same; whether you can roll on polyurethane still depends on a few factors.  

At the end of the day, it depends on where you intend to apply polyurethane. For example, oil polyurethane is best applied on wood floors. Because of this, you can’t expect it to have the same finish quality as water-based products.

Saves Times & Faster Dry Time

If you look closely, you’ll see that the paint roller frame operates in a free-spin movement. Thanks to this, the roller minimizes splatter during usage and saves you from the extensive cleaning process.

They can also come in handy when applying fast-drying water or oil-based polyurethane. 



Whether you want to buy a microfiber or foam roller, the truth is it’s an expensive material. After comparing the price range with brushes, it’s hard to ignore that the latter are generally affordable. 

Paint roller products don’t last as long as other alternatives, so we don’t suggest using the same roller in different projects if you want to ensure the application’s best quality. 

Hard to Prevent Bubbles

Some newbies may not know, but bubble formations are highly likely to happen when you apply polyurethane with a roller than with brushes. Since rollers aren’t the best for detail painting, you may need a brush for the final coating. 

Hard to Coat Edges and Joints

A paint roller can deliver a smooth finish in flat materials, but you’ll have difficulty using it for detailed work like painting edges and joints.

While you can opt for a mini roller, it’ll only work if the wood materials are small and uninstalled. Needless to say, brushes are still needed for the first coat. 

Applying Polyurethane Using a Roller: Step-by-Step Guide

Necessary Tools

Step #1: Get the Materials Ready

Get two cups each of mineral spirits and polyurethane. To be clear, they shouldn’t be in one paint pan because they should be stored separately. While prepping these chemicals, don’t forget to wear goggles and other safety gear to protect yourself. 

Step #2: Soak Your Roller in Mineral Spirits

The next step is to soak the paint roller with mineral spirits. Shake it off lightly to ensure no dripping, especially if using a high-absorbent foam roller. 

Step #3: Soak the Roller in Polyurethane

After the first coat on the foam cover, dip it into the polyurethane tray immediately. This method should mix the poly with mineral spirits, and it’s ready to go.

Step #4: Apply the First Poly Coating

Once the wet polyurethane and mineral spirits are mixed in the roller frame, it’s time to apply your first coat on the wood. Apply polyurethane fast and cover as much area as you can.

Step #5: Repeat the Application As Needed

Continue applying the coat in long strokes as long as it’s even. Check if you didn’t miss a spot on both ends of the surface. However, be careful in adding too many coats as it may result in bulging, so you need to know how many poly coatings you need to apply

Step #6: Sanding the Surface

After the application dries, you need to sand it with 250-grit sandpaper or higher. You can eliminate sanding dust produced during this step with a tack cloth soaked with mineral spirits. 

Step #7: Store the Roller in Between Coats

During the sanding process, your roller for polyurethane shouldn’t be lying around in random places. Make it damp again by soaking it in the mineral spirit’s pan. Place it inside a freezer bag as it dries to wipe on poly and remove the excess. 

Step #8: Paint on Extra Coats

You can apply additional coats of polyurethane with a roller, but don’t stir away from the recommended instructions. Let each coat sit according to the required drying time.

Step #9: Cleaning Up

Even the best roller for polyurethane application needs to be cleaned, so don’t store it when it’s still damp from chemical mixtures. You can also dispose of both the roller and pan if they’re in no condition to be reused. Otherwise, clean them with hot water.

Typically, your countertop paint kit includes instructions on the recommended number of coats. It’s often three for the best results, but you must know that a full coverage application requires more than that. 

Do I Still Need to Sand the Surface?

Yes, you must sand the surface for a smoother finish. If you don’t do this method, it could result in uneven surfaces and bubbling.

Lambswool Rollers

These rollers are designed with natural fibers, so it’s not surprising that they absorb polyurethane well. There’s also no shedding that leaves unwanted streaks or spots on the surface. 

Foam Rollers

You can count on a foam roller for applying oil-based poly because they are highly absorbent. The only problem is it can cause streaks when applied with water-based polys. 

Microfiber Rollers

If you want no signs of streaks or marks, microfiber rollers are your best option. These are made of multi-layered cloth, making them durable and long-lasting when maintained properly. 

Safety Measures to Consider

For your safety, you should apply polyurethane in a well-ventilated area. While you can roll polyurethane on easily, don’t forget to wear protective gear like gloves, masks, and goggles to avoid harmful fumes produced by these chemicals.
