My Best Rollers for Applying Polyurethane to Wood

By MWB-Team •  Updated: 12/31/23 • 

There are various methods to apply polyurethane, such as using a brush, sprayer, roller, or T-bars. Each method has its pros and cons, and in this article, I’ll discuss rolling polyurethane and share some of my best roller recommendations for this task. Additionally, if spraying is your preference, you can also check out our guide on the best sprayers for polyurethane.

My Polyurethane Roller Buying Guide

Types of Roller Cover Material for Polyurethane

There are different kinds of rollers you can use for polyurethane, including foam, microfiber, and lambswool rollers. Each of these types of foam materials comes with its pros and cons. Let’s look at each one below.

Lambswool or Mohair Rollers

Lambswool and mohair rollers are the two natural types of roller cover materials. These rollers are great for applying oil-based finishes, such as oil-based polyurethane. However, they can also be used with other finishes and still provide an excellent finish. Depending on the nap size, lambswool, and Mohair rollers can be used on smooth or rough surfaces.

Foam Rollers

As the name implies, a foam roller is made with a solid foam-like spongy material. This material is soft and porous, allowing it to absorb liquids easily. Foam rollers are great with thinner paints and finishes, making them suitable for water-based polyurethane or other thinner finishes.

Because of the smooth surface of the foam, they redistribute finishes evenly without leaving any surface marks. Foam rollers can be a problem when used on rougher surfaces due to their smooth nature. Compared to other types of roller materials, foam rollers don’t last as long and are usually considered ‘single-use’ covers.

Microfiber Rollers

Microfiber rollers are relatively new to the scene and can be identified by the diagonal stripes on their plush cover. They are great for different finishes, including oil-based finishes and oil-based polyurethane. They also leave a smooth finish but are best used on smoother surfaces for the best results.

Microfiber rollers are made from a combination of different synthetic materials such as nylon, polyester, kevlar, polyamide, Nomex, trogamide, and polypropylene.

Compared to other types of rollers, microfiber rollers pick up more paint but hold the paint until it is applied to the surface, minimizing splatter. They can also be reused on another project by washing them after applying a finish.

Oil-Based vs. Water-Based Polyurethane

Oil and water-based polyurethane both respond differently when applied using different roller cover materials. Oil-based polyurethane is thicker/more viscous, making it harder to spread. On the other hand, water-based polyurethane is thinner and also dries fast, which can make tracking your progress more difficult.

While you can use different rollers for both types of polyurethane, it is better to choose the best option for the polyurethane you’re applying. For oil-based polyurethane, a natural roller like lambswool or mohair is great. For water-based polyurethane, a foam or microfiber synthetic roller is great.

Roller Nap Size Explained

Different rollers come in different thicknesses of fibers, also known as the nap. A thicker/higher nap size will pick up and hold more finish, while a smaller nap size will pick up less paint. If you want a smooth, quality finish, a smaller nap size is the best choice.

Apart from holding more or less paint, the different nap sizes also determine the surface you apply a finish. A rough surface will require a higher nap size, while a smoother surface will require a lower nap size.

Rolling vs. Brushing Polyurethane

Using a roller or brush is a great way of applying polyurethane. Rollers are great for applying poly on larger areas; however, brushing will deliver better results, especially with clear finishes like polyurethane. When rolling polyurethane, you should also be careful not to introduce bubbles.

However, when properly rolled, you can be sure of a smooth and even surface free of brush marks. To avoid thick coats along the edges, use a brush to touch it up. You can also use a brush to back brush over rolled polyurethane for a smoother and even surface.
