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.

Frequently Asked Questions about Polyurethane Brush

1. Are natural bristles better than synthetic ones?

The performance of different bristles varies upon the form of paints. Natural bristles work better with oil-based paints; while synthetic bristles are great for water-based ones.

2. How to get a neat finishing with polyurethane application?

To get the smoothest finishing with polyurethane application, you should start by applying a thin layer. Then, use sandpaper to remove any dust on it.

To give it an even shinier finishing, use automotive paste wax.

3. Why does my polyurethane leave brush marks? 

The remaining brush marks occur due to the lower quality of polyurethane brushes. If the brush is not soft enough, such marks will arrive.

It can also happen because of the polyurethane drying off too fast. So, you might check the consistency of your polyurethane before application.

If the consistency is fine, then switch to a soft and higher-quality brush for polyurethane application.

4. Are foam brushes bad? 

Foam brushes can be a much cheaper substitute for natural or synthetic brushes. With the right amount of experience, these brushes can give you excellent results.

The only bad effect of foam brushes is that they create bubbles. So there is a huge chance of your polyurethane becoming uneven after it dries.

5. Is rolling polyurethane better than brushing it?

Rolling polyurethane may seem better than brushing it because the application process is much simpler and it produces good results with minimum skills.

But rollers cannot cover edges and corners properly. For such areas, brushing polyurethane is a must.

6. How to achieve the best results by applying polyurethane? 

Use a good-quality bristle brush to apply the first thin coat on the surface you want to cover. Then wipe the excess with a clean piece of cloth. With the right brush, it is that easy!
