Different Types of Brushes for Polyurethane Finish

There are various types of polyurethane brushes depending on their material, usage, and maintenance. Different types of brushes are suitable for different kinds of applications. Below are listed the types of polyurethane brushes and their details.

Natural Bristle Brushes

These brushes are made of animal furs- like a hog, boar, or badgers. Although they are quite more expensive than artificial bristles, their performance is also better.

These types of brushes are good for oil-based polyurethane. Natural bristle is extremely durable and they rarely leave loose strands behind, which makes polyurethane applying easier.

Synthetic Bristle Brushes

Synthetic brushes are more affordable and their durability is spot-on. These brushes are incredibly versatile, and therefore; they are used by most people. The texture of these brush too are even and they provide you with a smooth finishing.

There are also different types of synthetic bristle brushes. The most common two types are- polyester and nylon.

Polyester brushes are great for applying water-based paints; while nylon works fine with both water and oil-based paints.

Foam Brushes

Foam is a good option for those who are looking for cheap brushes. The flexibility of these brushes allows you to cover different areas of your piece effortlessly.

Using foam brushes is more like varnishing. They are great for small DIY projects.

These are so cheap that you can just throw out used ones and take a new one for every use. Thus, you wouldn’t have to spend time cleaning the brushes.

Things to Consider When Buying A Brush for Polyurethane Coating

Every brush will not be good enough for every type of polyurethane application. There are some crucial things to consider before buying a brush. Below are mentioned the things you should keep in mind.

Bristle Type:

The thing that makes the most difference with polyurethane application is the bristle type.

As mentioned before, there are various types of bristles, made of different materials and serving different purposes.

Whether you need a natural, synthetic, or foam brush depends much on the polyurethane form you are going to use. If you don’t use the suitable bristle according to your polyurethane form, you will not gain expected results.

In short, use natural bristles for oil-based polyurethane and synthetic ones for water-based paints. You may use foam brushes for any type of polyurethane, but the result will be not as fine as natural or synthetic brushes.

Brush Size:

There are different sized brushes available in the markets. Some are tiny, some are large enough to cover a wide area.

Generally, small brushes can be used for all purposes. Since these brushes are easy to use on edges and small holes, they produce precise results.

But applying polyurethane on floors or walls takes tons of time when using small brushes. For such purposes, larger brushes are preferable.

You may find comfort by using both types of brushes at once- large brushes for wider surfaces and small brushes for edges.

Bristle Shapes:

Bristles come in different shapes, such as square-cuts and angled-cuts. For different types of surfaces, the bristle shape varies.

If you are going to apply polyurethane on an even surface, square-cuts are perfect for you. But to neatly apply it on edges and corners, you may need angled cut bristles.

Bristle Tips:

The tip of bristles is usually flagged or tipped. The flagged bristles are of superior quality and provide smoother application results.

Tipped bristles, on the other hand, are more liked by professionals. These brushes ensure better control and are able to hold more paint, which makes polyurethane applying easier.

So it is up to you which results you prefer.

Why does my polyurethane leave brush marks?
