When it comes to painting, a good brush can make all the difference. In this acrylic paint brush guide, we’re make things super simple and breaking down everything from size, brush type, and bristle hair so you can find the right acrylic paint brush for your next project.

Bristle hair

Depending on the medium you use, this will depend on the type of brush hair that you choose. Though synthetic or taklon brushes are best for acrylics, there are still alternatives if you’re wanting more control over your texture.

Natural hair bristles

Natural hair brushes are more expensive than synthetic brushes, although there are plenty of synthetic brushes that are made to replicate natural brush hairs, like sable hair brushes. From pony hair to sable, below are the natural bristle hair types.

Range of different Mont Marte acrylic paint brushes of different sizes and lengths.

Sable

Sable are often used for watercolours because of their delicate hairs, can be used for acrylics, particularly in thin detailed brushes or round brushes. A sable hair paint brush may be your preference over a synthetic, because it will hold its long, thin bristle shape. It will swell at the grip, then taper in finer at the end.

Hog bristle

The hog bristle is mainly used for oils but these brushes can still be used for acrylics, thanks to their stiff, dense hairs. Hog bristle hairs are split at the end, these splits are called ‘flags,’ and this is what lets them absorb a lot of paint. Apply impasto or thick layers with ease, with this type of coarse brush.

Goat hair

Goat hair is coarse but not as springy as a sable. Goat hair forms at a sharp point and is best used for blending or to create even glazes. Because of its sharp, fine bristle point, these brushes will be better for evening out surfaces instead of applying colour to canvases.

Pony

Pony hair is also used for brushes, this is because their bristles are soft and have a tapered tip, not to be confused with horsehair, which has a blunt tip and coarser fibres. Pony hair is better suited for thinner viscosities of acrylic and less detailed work, so try splaying the brush or using its side.

Badger hair

Badger hair, paint brushes have stiff bristles making them great for producing smooth, thick brush strokes. This type of brush is great for acrylics, and as a handy tip, can also be used to apply varnishes for a smooth finish.


Synthetic bristles

Synthetic bristle brushes are much easier for acrylic painting. This is because, they are simple to clean and can withstand the pressure and handling of acrylic paint.

Taklon

Taklon bristles mimic natural hair bristles like sable to spread paint evenly and smoothly. Acrylic paint dries quickly so pay attention to washing your brushes. Be sure to moisten the bristles with water first before going in with the acrylic paint, to protect your bristles.

Brush sizes

When it comes to paint brush size, all manufacturers are different. As a rough guide, the higher the number, the bigger the brush will be. Brushes above size 6 are perfect for broad, strokes and cover large surfaces. Brushes from size 4 to 6 are great for painting small areas and those brushes below size 4 are great for more detailed and intricate work. When it comes to flat brushes, these are measured by their width in inches, for example ½”.

Types of acrylic brushes

Round brushes
