Acrylic Painting Brush Techniques

There are various types of brushes and stroke techniques that artists use to create different effects with acrylic paint!

If you are the absolute beginner to acrylic painting, this post is meant to help you build some basic skills when it comes to selecting the right brush and its purpose.

Practice these techniques in your sketchbook! Use this as a reference when you are painting!

Brushes I Use: 

I like Royal & Langnickel brushes. This is the introductory set that I use and it has lasted me well through a lot of paintings that I do on this blog. There’s a few other brands in the mix but I tend to gravitate to my Royal brushes. I think if there is a brush that works well for you, stick to it! You may have different preferences and that is fine.

The above graphic is by no means a list of all the brushes that exist!  I left out the filbert brush which is like a flat but has a rounded tip. A palette knife can be used as a brush to apply thick “impasto” strokes.  There’s even odd shaped brushes like zig-zag edged and v-shaped!

Also note that these are all synthetic brushes! When I am shopping for brushes, I make sure the label says they are meant for acrylic paint but also that they are synthetic. Why? The bristles are soft but still firm, which make it ideal for painting with acrylic paint. Also, the synthetic material can withstand the acrylic paint and allow for easy cleaning.

How are brushes labeled? Sometimes it depends on the brand. Wouldn’t it be more interesting if brushes were called fun names like “Harry” and “Louie”? That way we’d all know exactly which one! Oh well.

Brushes are typically labeled with names like “flat” or “round” or “bright” and a number. Usually the smaller the number, the smaller the brush! Everyday objects like old toothbrushes can be used too!

Common Brushes

  • Basecoat: Basecoat brushes can be used for painting an entire canvas with gesso or varnish. It can also be used to paint an extremely large area or if you want to paint the entire canvas one color like black!
  • Flat or Bright: Flat brushes are used to get a sharp edge or if you want to paint a large area. They vary in sizes and usually are labeled with a number or  how many inches wide they are (1″, 3/4″, etc.). Often times we hear “bright” used. A bright is also a flat brush but the bristles are shorter.
  • Angle:  An angle brush has many uses! I like to use this when I want my paint strokes to come to a fine point (like tree branches).  It’s also perfect for “cutting in” sharp edges or creating zig-zag strokes and double loading for a blended look!
  • RoundRound brushes are typically labeled with a number. The smaller the number, the smaller the brush. Use round brushes for filling in small areas. Also use them for fine details and tiny stokes!
  • Fan BrushA fan brush is fun to experiment with! I don’t use it often but they are great for painting palm tree branches, pine trees, waterfalls, etc.
  • Filbert: Similar to a flat but has a rounded top. Great for blending and creating smooth edged strokes.
  • Everyday ObjectsUse an old tooth brush for a splatter paint effect! This is great for painting stars in a night sky. A lot of everyday objects can also be used as a brush: Q-Tips, sticks, feathers, fingers…

My Favorite Brush Techniques

This is not an inclusive list at all as there are many! These are just some of the ones that I love using in my paintings!

  • Dry Brush
  • Round Brush Techniques
  • Angle Brush Techniques 
  • Flat Brush Techniques 
  • Cross-hatching
  • Double And Triple Loading
  • Blending
  • Stippling
  • Using A Fan Brush
  • Splatter Painting

Dry Brush 

Dry brushing is a technique used by artists to make the paint look “feathery” or “dry”. Any brush can be used for this technique.

When you do a dry brush stroke, use a clean brush with no water on it. Dry it with a paper towel.

Load just the tip with a little bit of paint. You only need to get paint on the tip! If you load too much paint, wipe some off with a paper towel. 

Dry brush strokes are light and feathery and need no water on the brush

Then lightly apply the paint on the canvas! The strokes always remind me of a crayola marker that is running out of ink. It looks translucent and you can see the texture of the canvas or the color underneath.

Some examples of instances when a dry brush technique would look great are: sunset clouds, grass, waterfall, wood texture and more!

 

Round Brush

Typically, you use a round brush for small strokes and filling in smaller areas. Round brushes come in several different sizes and most brush brands label them with a number. The smaller the number, the smaller the brush.

Use a size 0 brush to paint tiny strokes. There are brushes that are smaller than size 0! You may see them labeled with a number like 5/0. In my tutorials, I usually refer to it as a “tiny detail brush”.

Use a larger number if you are filling in a medium to larger area (such as a silhouette). Or, use it to create medium rounded “free-style looking” strokes.

Angle Brush

 

An angle brush is a handy brush to grab if you are painting trees or want to achieve a nice zig-zag stroke! I like to grab it when I want to “cut in” when painting a large object.

When you use an angle brush, try experimenting with the pressure of how you are holding it. See what happens when you press hard verses if you press light!

Experiment with turning your hand at different angles. The line will get thicker and then thinner when you turn your hand.

Try using the very tip (highest corner point in the angle) to paint fine lines. When I painted the smaller tree branches above, I pressed lightly only using the highest bristles of the brush!

You can also use an angle brush for double loading! I will be demonstrating how to double and triple load next in this guide!

Double Load

When you double load a brush, you are essentially adding two different colors to the brush without them mixing together.

You can use a flat brush or an angle brush for a double load. Actually, I’ve even used round brushes for this!

First dip one corner of the bristles in one color. Then dip the other corner in the other color.

Dip each corner of the brush in a different color.

 

Double loaded one stroke with orange and yellow

When you paint a stroke, the two colors will naturally blend together!

Try experimenting with this a bit! I like to double load when I’m painting a sunset. The colors will mix together on the canvas!

See what happens when you use an angle brush for double load! One side will be thicker than the other.

Experiment with different lines, curves, zig-zags, etc.!

Triple Load

One of my favorite ways to blend acrylic paint is letting them just mesh together right on the canvas (or paper)!  Adding three colors to the tip of a flat brush is one way to do this.

When you triple load a brush, dip the entire tip in one color first. Then, like a double load, dip each corner in a different color!

White, Turquoise and Black triple loaded brush created this blended color mix!

Try experimenting with three colors you think will mesh well together! I like using a triple load for the base of a lot of my paintings! The above graphic is a triple loaded brush with black, white and turquoise painted with all up and down strokes.

Flat brushes

Flat brushes are such a versatile brush. Use one when you are filling up large spaces such as sky or water. I will demonstrate two of my favorite ways I use the flat brush!

Painting a sky

I like to use flat brushes for blending colors directly on the canvas when I’m painting a sky. In the graphic you see below, I used the flat brush two different ways. Horizontal  strokes and “X” strokes. Those “X” strokes are also called “cross-hatching”.

Horizontal strokes and “X” strokes made with a flat brush.

 

I added white on the paper to blend the blue with the same kind of stroke.
Painting Thick then Thin Strokes with a flat brush

First press firm on the bristles. Then twist the brush and stroke up to use just the side of the flat brush. The stroke starts out very thick and then gets thin.

Try doing the same thing but with a double load! In the graphic below, I double loaded a flat brush with white and green.

 

Flat Vs. Bright

Is there a difference between a flat and a bright? Kind of. I grab them interchangeably. Bright brushes have slightly shorter bristles which allow for better control. If you’re a beginner, then bright brushes are your best friend! Flat brushes have longer bristles which could hold more paint, making them great for painting skies and filling in large areas!

 

Cross-Hatching 

Cross hatching simply means that strokes are overlapping going in two different directions. There are many combinations you can do with cross hatching.

Vertical and horizontal cross hatching is one way. I don’t typically use this technique in my paintings but it is a unique way to blend colors or add interesting texture to a painting.

 

Cross hatching in “X” strokes is a technique I do love and use a lot! Any brush works for cross-hatching, I just happened to use a #3 round brush for this demonstration.  In the above graphic, I cross hatched phthalo red and yellow together to create a unique texture and blending style.

 

You can also play around with wet on wet, wet on dry, etc. In the above graphic, I experimented with using diagonal cross hatching strokes. I added multiple layers of the cross hatching pattern without waiting for the under-layer to dry (wet on wet).

 

Splatter Paint 

Call me a crazy former Elementary Art teacher but I LOVE splatter painting! If I could add splatters to all my paintings, I probably would.

The best tool, I think, to splatter with is an old toothbrush. I find that wetting it SLIGHTLY helps. If you put too much water on the toothbrush, you’ll get undesirable large drips everywhere. Try experimenting with the angle of the toothbrush or the amounts of paint. Also, it’s best to try on a separate paper first before throwing it on the canvas.

 

If you don’t want to use a toothbrush, using a regular brush works too! I sometimes grab a flat brush to splatter with because I want more control in where I want my splatters to go.

 

Stippling

I use the stippling technique sparingly in my paintings. I think this technique is more effective in other mediums like oil pastels so I don’t use it all too often with acrylic paint. Basically, you are painting little tiny dots using the tip of a round brush! It can be an effective, yet tedious, way to blend colors together.

Using A Fan Brush

A fan brush can be used to create a lot of different techniques. One of my favorite fan brush techniques is painting pine trees. To do this, I used a round tiny detail brush to paint the vertical trunk. Then I used the fan brush tips like a stamp and from the top to bottom I painted the branches. You can see my separate post “How To Paint Pine Trees With A Fan Brush” here. A fan brush can also be used for creating grass effects and other interesting ground and natural textures. You can even use your fan brush if you are painting a waterfall!

Use your fan brush like a stamp to create interesting ground textures. Experiment with different colors.
Paint grass textures with the fan brush by making short strokes going in different directions.
Create waterfall effects with fan brush by dragging it down and adding layers of blues and white.

Some Final Thoughts:

I think having a sketchbook is important to practicing brush and stroke techniques. I use a basic sketchbook with regular drawing paper and I don’t really worry about the paper crumbling from the paint because it’s just practice. Do basic exercises frequently in your sketchbook to help refine your skills. Acrylic painting takes practice and the more you train your hand and mind and spirit with the skills, the better you will get!
