Buyer’s Guide

What to consider when buying the best brush for polyurethane? Well, currently, there are many brands and models of brushes for polyurethane flooded in the market today, and picking the best for your projects might prove challenging. However, with the right information on what to look out for, you can easily get the right brush for a perfect finish! Below are some of the factors to consider when buying the best brush for polyurethane.

Type of Bristle

The type of bristles the brush comes with makes a big difference in applying polyurethane. These brushes come with either natural bristles or synthetic bristles.

Natural bristles that are made from animal hair tend to work well, especially with oil-based finishes. Synthetic bristles, on the other hand, are great for use on rough surfaces or when working with water-based finishes.

Width and Style

When it comes to deciding the kind of width and style of brush for polyurethane you want, you have to think about the kind of project you are handling. A wide width can be considered if your project is big while a narrow width can be considered for small projects. A two-inch angled brush works great for small application projects while a four-inch flat brush can be ideal for large-area applications.

Type of Handle

The type of handle a brush comes with matters a lot, and most painters, especially first-timers, downplay its role. Every handle type is designed for a particular task. A short and dense handle is best at working on small projects but if your task is a bit bigger, a big and well-contoured handle for a firm grip is best because it provides comfort when applying.

Ferrule

Before you commit your money to a brush for polyurethane, ensure the metal band that keeps the bristles in place is firm and secure. Tug the bristles gently to see whether the ferrule is securely placed.

Quality

When buying a brush for polyurethane, most people tend to compromise on quality in order to save money. However, you should keep in mind that cheap is expensive. We, therefore, recommend that you invest in a high-quality brush if you intend to make a perfect application.

How do you brush polyurethane? is there a difference in the application if its an oil or water based?

You can brush polyurethane in the same way you would brush paint. If there are any bubbles, gently brush back over the finish to burst them.

When possible, brush along the grain of the wood. Oil-based paints dry in around 8-12 hours, so they’re considerably better at leveling off and creating a smooth, brush-mark-free surface.
Most water-based paints dry in 30 minutes to an hour, which isn’t nearly enough time to completely level out. while applying water-based polyurethane you have to be extra careful.

How do you fix polyurethane brush marks?

Removing Polyurethane brush marks can be tedious. You can follow these simple steps to fix brush marks:

1. With the fine-grit sandpaper, softly sand down the brush markings while applying even pressure to the area.
2. To remove any traces of dirt and grit from the sanding, wipe it off with a soft cloth. These particles may become trapped beneath the finish.
3. Apply a light coat of polyurethane finish to the brush, wiping away any excess. This will prevent the area from getting too much finish.
4. Apply the finish with as few brush strokes as possible to the sanded surface. It may take many light applications to achieve the ideal look, but this is preferable to overdoing it. If the coating appears to be too thick, softly wipe the surface with the rag until it is even. Allow the polyurethane finish to cure before proceeding.
5. Look for brush strokes on the dry area. Re-sand the furnishings if any remain.

Is polyurethane easy to apply?

If you are applying polyurethane for the first time the task can be difficult. Polyurethane must be applied in long, even strokes. You must also keep a wet edge.

If you touch an area with your brush that is dry or drying, you’ll pull the finish, which could leave bumps when it finally dries. These bumps will need to be sanded. You’ll need to lightly sand cured layer to apply subsequent coats. This, once again, entails additional time and work.
