Types of filament
Filament are the long strands or hairs on a brush. There are three types of filament to choose from
- Synthetic Filament: good for all paints, best with water based paints
- 100% Pure Bristle: best with oil based paints
- Polybristle Blend: best with oil based paints
Style of brushes
- PAINT/WALL BRUSHES: these are the most standard and
common type of brush. With a short handle in comparison to the cutter
bushes they come in various widths for various painting jobs.
- CUTTER BRUSHES: These are popular brushes for
cutting in before roller painting. Specially made for door and window
frames and ceiling/wall/corner sections. They generally have less
filament than wall brushes as paint holding capacity is not paramount
while the long handle helps to control the stroke. There are several
shapes in these long handle brushes.
- Sash Cutter: is a full bodied cutting in brush ideally suited for the application of water based paints.
- Oval Cutter is a compromise between the two other styles because of its oval shape. It gives greater control and accuracy on the edges of the brush and holds more paint in the centre
- Angle Cutter is basically the same as the sash cutter however the top of the brush is made at an angle rather than straight across. The head of the brush and the ferrule are both made at an angle so that the tips of the filament or bristle are retained. This angle assists the user to be able to cut to a sharper more accurate area.

Quality of brush
A good brush holds more paint, makes paint application smoother and reduces paint spattering. A quick way to check this is to feel the pack of filament. It should feel full and slightly resilient. Although cheaper brushes will not last as long as premium grade brushes they are quite suitable for the occasional job where finish, quality and brush life are not critical.
