Not all brushes are created equal
A high-quality paint brush is made of several different components, that all combine to create the perfect tool for the perfect finish. Here Andrew Cummins, Senior Product Manager at Purdy, breaks down the different parts of a brush and what you should look out for in a high-quality product.
The bristles
The bristles of a paint brush are made up of thousands of individual filaments. High-quality filaments should be SRT (Solid Round Tapered) and made of durable synthetic nylon or polyester which simulate natural fibres but don’t damage as easily. Some brushes are also tipped and flagged to aid paint pick up and lay-off. Brushes with self-flagging filaments, such as Purdy's, will continue to perform over time, even as the bristles wear down.
The ferrule
The ferrule is the metal collar that connects the bristles to the handle. As ferrules can be prone to rust, it is important to select a brush with a ferule made from corrosion resistant stainless steel or copper. The ferrule is then connected to both the bristles and to the handle – brushes that are bonded with a strong epoxy are the best choice, to avoid loose filaments, while corrosion resistant nails will ensure the handle and ferrule stay together. With all Purdy brushes, an additional wooden plug is embedded within the bristles under the ferrule, creating a reservoir for better paint retention.
The handle
Many manufacturers recommend wooden handled brushes as these absorb moisture throughout the day: this reduces the amount of friction the user feels and also stops the handle becoming slippery. A brush with a handle made of a hardwood, such as Alderwood, will be lightweight and comfortable in the hand but strong and able to resist day-to-day wear.
