Paint Brushes Fill Material

Many of our standard paint brushes use pure bristle fill because this soft, natural fiber has naturally split ends making it ideal for carrying and holding liquid. Pure bristle also has a tendency to maintain stiffness and shape over time. Bristle is soft and is perfect for use with thinner viscosity materials such as oil based paints, varnish or polyurethane. This natural bristle is not recommended for use with water or alcohol-based coatings as the bristle tends to absorb the heavier liquid, causing limpness.

Synthetic filament options such as polyester are an economical alternative that can be used with almost any paint or coating, but is most often recommended for water-based, latex and emulsion paints. One of our paint brush products, the Round Wire Chip Paint Brush, is available with stainless steel fill, as this is an effective brush for use in high temperature or corrosive environments.
