Synthetic Brushes versus Natural Hair
For many years, a synthetic or manmade brush was considered to be suitable for painting the exterior of a house or similar jobs, but never for creating fine works of art. Modern technology has come a long way, however. Synthetic brushes are now made using a variety of different synthetic fibers, making them a top choice for creating beautiful artwork. Most synthetic brushes are made using polyester, which may be trademarked under various names, like Taklon, for instance.
Synthetic brushes can have many advantages over natural hair brushes, including:
It is notable that when working with acrylic paints, the natural hair brush is not a good choice at all. Because the natural PH of the hair in a natural hair brush is the opposite of the PH of acrylic paint, using acrylic paint with a natural hair brush can be destructive to the hairs of the brush. And since acrylic dries quickly it tends to accumulate on the brush during painting, which necessitates submerging the brush frequently in liquid when working with acrylic. For these reasons, if you like to work with acrylic paint (and lots of folks do because acrylics are affordable and easy to clean up), always go for a synthetic brush!
For those who desire the best of both worlds, there are also synthetic/natural mix brushes. These brushes use a combination of natural hair and synthetic filament – resulting in a brush that has increased absorbency (because of the natural hair) while being affordable (due to the synthetic fibers used). These brushes are often the ideal choice when working with watercolors.
