Best Roller for Polyurethane

When applying polyurethane, most people use a brush to spread the finish on a wooden surface. While using a brush may be the best option for certain projects, such as small projects with close edges, applying polyurethane on larger wooden surfaces may require using suitable rollers.

Rollers are considered in poly applications because they are more efficient than brushes for larger wooden projects. This article looks at the best rollers for the smoothest finish on your wooden surface with either water-based or oil-based polyurethane.

What to look for when buying roller for polyurethane

Oil vs. Water-Based Polyurethane

When choosing a roller for polyurethane, it is important to know the type of polyurethane you intend to apply to your wooden surface. Different rollers have a different affinity or the ability of the polyurethane to stick on the roller cover.

Oil-based polyurethane sticks differently to the roller than water-based polyurethane. For instance, for oil-based polyurethane, it is advised to use foam, microfiber, and lambswool rollers; this is due to the fact that oil-based polyurethane is thick and does not readily get absorbed by the roller. These rollers allow oil-based poly to be applied smoothly and evenly over the surface.

On the other hand, it is not advised to use foam rollers when it comes to water-based polyurethane. This is due to the fact that the thinner nature of water-based polyurethane gets absorbed inside the more porous foam roller covers. 

Surface

The type of roller used is also dependent on the type of surfaces you intend to apply the polyurethane. A rule of thumb is longer rollers are best suited for larger surfaces such as floors, or patios. These rollers require longer roller frames to be effective at covering larger surfaces in the shortest time. On the other hand, smaller surfaces such as those of furniture are best suited to shorter rollers that allow for more maneuverability. 

Sheen

When choosing a roller it is important to consider the sheen you want for the finish. This is due to the fact, that different rollers affect the sheen of polyurethane differently. Roller covers with porous surfaces are not ideal as they absorb the poly and result in a very thin layer of poly that is poor in sheen. To achieve a better sheen it is recommended to use high-density fiber rollers or lambswools which do not absorb the poly.
