Acrylic Painting Studio Tips - Brushes 101

All About Brushes


Of all the things you spend money on in the studio, let brushes be at the top of the list.  This is a quick overview from an acrylic painter's perspective. 

  • Buy good brushes for the important stuff and cheap brushes for the rest. What does that mean? If you really need to get a good line over two feet of canvas, a cheap brush will not do the job. However, if all you need to do is slather soupy paint all over the background, any old brush will do.

  • Take good care of your brushes and they will last a long, long time.

  • Never leave your brushes standing in water or thinner.

  • After washing your brushes, lay them flat on a paper towel or cloth to dry. This will prevent water from getting into the ferrule and loosening the glue that holds the bristles.


The Anatomy of a Brush

A brush has three main components; the handle, the ferrule and the bristles.  

  • Watercolor brushes have short handles - apparently so the artist won't poke themselves in the eye because they tend to work closer to the paper than artists painting at an easel.

  • Easel brushes are so named because they have longer handles and are useful when working at an easel, giving the artist the option to work at arm's length.

Brush Shapes

There are many types of brushes, both in shape and type of hair or fiber used to create them.  The four main shapes that I use the most are: 


Although the last time I checked on there are at least eleven different shapes of brushes.  Check out the chart here.

Each shape has a particular use. Rounds are good for curvilinear lines, filigree types of marks and flourishes. Flats are useful for long straight lines.  A good flat brush can be loaded with paint and make a very long straight line, depending on how big the brush is. Brights are great for short, choppy paint strokes like you might see on an Impressionist painting. Filberts make rounded paint strokes and are very useful for filling in rounded shapes.

Brush Hair or Fiber

Brushes come in two main types of hair: natural and synthetic.  I like and use both.  The natural hair that I use the most is hog bristle. The Robert Simmons Signet hog bristle is my favorite brush line. These are durable workhorses and really take a beating in my studio. They clean up well and come back for more.  I can't live without them. 

Of the synthetic brushes that I use, I prefer the Robert Simmons White Sable brushes for softer washes and more delicate work. 

There is an excellent article here by Will Kemp about brushes. I highly recommend it! 

Brush Sizes

This gives me a headache! There is no standard sizing for artists' brushes.  Eeek! Imagine shopping for shoes and the manufacturer just randomly uses any old size they like.  Sigh.  About the only thing you can count on, is that a larger numbered brush (8) will be bigger than a smaller numbered brush (4) from the same manufacturer.

This is probably the reason I've been using Robert Simmons brushes for so long, I know what to expect from their sizes.

Caring For Brushes

If you're an acrylic painter, take care not to let the paint dry on the brushes.  That's deadly.  You can bring them back with some really strong cleaners, but the brushes will never be the same.  I like to clean my brushes with this soap from Masters. This is actually the hand soap that Masters makes but I like to hold the soap in my hand and then rub the brush on the soap to get it clean. This gets my brush clean and my hand at the same time. And the brush never touches my skin.

Do me a big favor. Never, ever, ever, wash your brush in the palm of your hand. Why? Because you are grinding the paint right into your skin.  Not a good idea. 

Although this is not a complete look at brushes by any means, this overview will get you started.  Send me your questions and comments and I'll be glad to answer them.
