How to choose the right paintbrush

Do you have a painting project in mind? Before you get started, make sure you have the right paintbrush for the job. Here’s what to consider.

1. THE BRISTLES

Paintbrushes can have either synthetic or natural bristles. The latter are especially resistant to solvents and are thus the better choice for applying oil-based or alkyd paint. If you plan on using water-based paint — acrylic or latex, for example — opt for a brush with synthetic bristles, which won’t expand when wet, to ensure an even application. Synthetic bristles are more durable and easier to clean than natural ones.

2. THE SHAPE

Paintbrushes come in different shapes, such as flat, angled and tapered. To make the right choice, consider the task at hand. For trim and other types of precision work, opt for an angled paintbrush designed for tracing fine lines. To cover larger surfaces, go with a flat-tipped brush, and use a paintbrush with tapered bristles to paint uneven surfaces (pipes, furniture, grills, etc.).

3. THE SIZE

As a general rule, the bigger the surface you intend to paint, the bigger your paintbrush should be. Choose a brush that’s at least 10 centimetres (4 inches) wide for painting walls, floors and ceilings. To paint doors, cabinets and wide mouldings, use a brush that’s around 7 centimetres (3 inches) wide. Finally, brushes that are 5 centimetres (2 inches) wide or less are perfect for trim and smaller mouldings.
